Both sexes of this species have rather restricted yellow maculations. The males are distinguished from other species except atripes and palmarum by the combination of the prominent black setal brush and the shape of sternum VI (fig. 20) which has the
median and lateral lobes broader than long. The apical lobe of sternum VIII provides a key character for the males of A. collectum since it is entire and reflexed (fig. 21). Tergum VII (fig. 19) is about the same as in A. atripes, whereas the lateral lobe of the tergum is much broader than in palmarum. A. collec¬tum females are most easily confused with pallidic-lypeum and utahense. The females of collectum have a wide posterior marginal band (fig. 83) that is curved near the dorsolateral extension and the basi-tarsus with dense white pile. These features, together with the nearly all yellow clypeus, which has the apical margin nearly transverse although wavy, will distinguish this sex. A. collectum is the second most abundantly col-lected species of this survey (386 3, 360 2 ). It is a fairly widespread species in California and has a similar distributional pattern to edwardsii except that collectum is much less frequent in the Central Valley. It is found in the Sierra Nevada Mountains, especially in foothill areas, and along the Coast Range into southern California. Three specimens have been col¬lected near Lone Pine, Inyo Co., which represent the only known records from the east side of the Sierra Nevada. A. collectum is the only species of Anthi-dium, except for palliventre, which is known from the Channel Islands. Collections show this species to be associated with nine plant families, but the majority of the records were in the Leguminosae, Hydrophyllaceae, and Boraginaceae, in that order. Preferred genera of these families were Lotus, Phacelia, and Cryptantha. Hicks (1929c) reported on the nesting habits of collectum at Pasadena and Sierra Madre, California, from March 31 to April 15, 1929. The females selected a deserted tunnel of some other insect or spider nests in the soil. The cells were constructed from down from the leaves and along the stem of Artemisia tridentata. One to two cells were con¬structed, depending on the cavity, and each cell was provisioned with pollen and honey. The bees filled the nest from the down to the surface with small pebbles, and at times pieces of leaves and stems, averaging 10 pebbles each minute. Copulation on the ground was observed, and resting and sleeping sites are discussed. Ferguson (1962) reported on the habits of col¬lectum in conjunction with a study of mutillids at Antioch, California. The females used other ground bee nests, lined the cells with down, and made over¬lays of pebbles and sand. Mutillid parasitoids included Sphaeropthalma (Photopsis) unicolor (Cresson). S. (P.) orestes (Fox), and S. (P.) blakeii (Fox). Other parasitic insects associated with collectum by Fer¬guson were the chalcid Monodontomerus montivagus Ashmead and the megachilid Dioxys productus cis-tnontanicus Hurd. Also a species of chrysidid, Chrysis coloradica Bohart (= C. pulcherrima Cresson), was reared from collectum by Ferguson. This species be¬longs to the lauta group as recently defined by Bohart (1964); and according to records made available to us by Bohart, Chrysis tripartita is also a parasitoid of collectum. At least one other member of the lauta group, C. florissanticola, is a parasitoid of the Anthi-dium as it was reared from A. banningense nest in Utah by Jaycox (in litt).
