Lanata was described by Horn as related \o pubiventris, but differ- 

 ing in abdominal sculpture and vestiture. On careful comparison I 

 am unable to discover any material difference in the ventral punctua- 

 tion of the two species, which is substantially as described of laiiafa. 

 The first segment is sparsely finely punctate at middle, and quite 

 densely at sides as is almost universally the case ; the following seg- 

 ments are finely rather densely nearly evenly punctate throughout. 

 The contrast between the punctuation of the first and second segments 

 at middle is striking, and peculiar in this group. All the specimens 

 of puhiventris in collections, so far as I know, were taken in Owen's 

 Valley, Cal. They were apparently long immersed in alcohol, and 

 the vestiture is almost entirely removed from the upper surface, and 

 from the abdomen except at the sides. I have no doubt that fresh 

 specimens would agree perfectly with laiiaia in this respect, as they 

 certainly do in abdominal sculpture. The markings of puhiventris 

 consist of rather large yellow (darkened by alcohol) spots, and are 

 quite constant as described by Horn. Lanata is typically vittate, but 

 a series from Utah and the desert regions of Southern California shows 

 forms varying from regularly through irregularly vittate to confusedly 

 maculate. In none of these are the size and disposition of the spots, 

 nor is there present the well-defined bluish surface lustre of the latter 

 (one example of lanata is very faintly bluish), but it may well be 

 doubted li puhiventris is anything more than a local race of the more 

 widely diffused Az/w/rt;. Length, 7.5-10.5 mm., .30-.42 inch. 



Habitat: Utah and desert regions of Southern California.

 A. fenyesi, sp. nov. 



Moderately stout, somewhat depressed, piceous, feebly bronzed, clothed with 

 long, fine erect hair, which is usually fuscous (sometimes paler) above, and grayish- 

 white beneath. Head feebly impressed, vertical carina indistinct. Thorax twice as 

 wide as long, sides usually straight for a short distance before the base, then gradu- 

 ally rounded to apex ; occasionally a little dilated before the base ; lateral margin 

 not visible from above except near the front angles ; surface moderately strongly 

 punctate, densely at sides, the punctures well separated at middle. Elytra with striae 

 of rather coarse punctures, intervals uniseriately punctulate, the fifth sometimes 

 slightly elevated as far as, or even beyond the middle ; maculation consisting of small
