MALE -Length 9-10 mm.; eyes convergent below; malar space nearly as long as broad; antennae brownish, median segments twice as long as broad; clypeus very closely and finely punctate beneath the dense pubescence; head and thorax pale ochraceous pubescent; lateral angles of pronotum not spined; metapleural protuberance not carinate; tegulae dark red; wings subhyaline, violaceous, veins and stigma ferruginous; punctures of scutum rather coarse, close laterally and anteriorly, somewhat separated in center posteriorly; punctures of scutellum slightly more coarse, slightly separated over most of disc; pleura dull, tessellate between the rather close, shallow, obscure punctures; legs somewhat reddened, spurs yellowish, abdominal terga shining, deeply and distinctly punctate, more coarse and well separated but not sparse on basal tergum, becoming closer and finer on the more apical terga; apical margins of terga reddish, hardly at all depressed, with entire whitish fasciate; discs of abdominal terga beyond the 2nd with some very short, inconspicuous, erect, dark pubescence.

DISTRIBUTION�Nova Scotia to Minnesota, south to Georgia; March to July, with occasional records in the fall.

FLOWER RECORDS�This is a pronouncedly polylectic visitor to a wide range of flowering plants. Personal collecting and records from Robertson (1929) and Stephen (1954) show the following list of genera as host plants: Aesculus, Amelanchier, Anemone, Anemonella, Arctostaphalus, Aronia, Cercis, Claytonia, Crataegus, Dendrium, Dentaria, Dirca, Erigenia, Erythronium, Hepatica, Heracleum, Isopyrum, Lomatium, Ploytaenia, Prunus, Ptelea, Pyrus, Rhamnus, Rhus, Ribes, Rubus, Salix, Spiraea, Staphylea, Stellaria, Taraxacum, Vaccinium, Viburnum, Zanthoxylum and Zizia.

Say says that his species flies in March and April. I have taken it from the 20th of March to the 28th of May, while the species which Cresson has doubtfully referred to C. in qualis I have taken only from the 30th of August to the 7th of October. This early species, which agrees wdth Say's description of G. in qualis, I have compared with the types of C. propinqua in the collection of the American Entomological Society. I have also examined the types of C. canadensis. A specimen which Mr. Cresson doubtfully referred to C. canadensis is nothing, I think, but C. in quali
