The females of mormonum have a distinctive ter-gum VI which consists of a prominent truncate pos¬terior marginal band that is posterior to, and v-idely separated from, the dorsolateral border (rU. 80 . There is no single character for identifying the rr.ale-:-: but the combination of a reddish setal brush pronounced lateral lobe of sternum VI (fig. 44) and tergum VII (fig. 43), which has the mean width of the lateral lobe subequal to the distance separating it from the center spine, will serve to distinguish this sex. Although many varieties have been described as "species" on the basis of coloration within mormonum, the variation that exists is not extreme within Cali¬fornia. The females usually have more yellow than the males. In extreme northern California, mor¬monum individuals are noticeably darker with less yellow on the thorax, abdomen, and pronotal lobe. This color pattern decreases even more in Washing¬ton and Montana. The darkest specimen was from northwestern Montana; it had a completely dark clypeus and mandible. This is the second most common species in Cali¬fornia as indicated by an examination of 491 males and 290 females. It is found in all the major moun¬tain ranges of California. Map 17. Distribution of Anthidium pallidictypeum Jaycox Hicks (1929a) has published relatively extensive notes on the biology of mormonum in a study of populations from southern California. Females were found nesting in deserted beetle burrows in old yucca flower stalks and oak stumps. The cells (numbering from 1 to 4, average 1.4) were lined with down with an overlay of pebbles and fine soil. The down was gathered from the hairy leaves and stems of Lepido-spartum squamatum. The nest was plugged with down. Hicks listed the megachilid Chelynia leucotri-cha Cockerell as a probable parasitoid. Examples of the nests of mormonum reared in studies by E. Jay-cox and F. Parker are presented in figures 218 to 220. The survey of mormonum showed an association with eight plant families, but records were predomi¬nantly from the Leguminosae (Lotus) and Hydro-phyllaceae (Phacelia).
