5 Abdomen not impressed basally in the male. Body larger and notably 

 stouter, very convex, opaque, the pronotum with black hairs; head 

 very coarsely punctate, closely toward base; prothorax in form nearly 

 as in laxicollis but with the aciculate murication finer and less dense, 

 the sides more explanate; elytra ( 9 ) at least a fifth wider than the 

 prothorax and almost twice as long, evenly oval, widest at the middle 

 as usual, the rugose sculpture more unevenly disintegrated, resolvable 

 into three or four relatively finer and closer uneven ridges, the gran- 

 ules smaller. Length (9) 14.0 mm.; width 7.7 mm. Southern 

 California (vicinity of San Diego). [Microschatia incequalis Lee.]. 



insequalis Lee. 



A Nearly similar to the preceding, except that in the female the 

 prothorax is nearly as wide as the elytra and in the male only just 

 visibly narrower, the prothorax not quite so strongly narrowed 

 anteriorly, the apex being somewhat more than one-half the 

 maximum width, with a peculiar oblique impression at each side 

 near the apical margin more evident, and the hairs usually not 

 black but fulvous, the small asperities slightly larger and denser 

 and having shining summits; elytra similar, except that the sculp- 

 ture is coarser, being resolvable into two very large irregular 

 ridges on each, the granules larger. Length (o 71 , 9) 12.5-14.5 

 mm.; width 6.5-7.6 mm. Southern California (vicinity of San 



Diego) diversa n. subsp. 



Abdomen with a strong and broadly concave medial impression toward 

 base in the male. Body moderately stout, black, opaque, the elytra 

 slightly shining on the elevated parts; head very coarsely, loosely 

 but subevenly punctate, not more densely so basally; antennae as 

 usual; prothorax rather more than one-half wider than long, nearly 

 as in iiKcqualis but much more coarsely muricate, more impressed 

 on the median line centrally, more strongly explanate and concave 

 laterally and with a more broadly concave basal impression, the 

 apex slightly more than half the maximum width; elytra equal in 

 width to the prothorax and two-thirds longer, oval, the two ridges 

 lower than usual, very much broken, the sutural line smoother and 

 somewhat concave, the apical slope also smoother than in the 

 preceding species; granules very conspicuous laterally; abdomen 

 coarsely, moderately closely punctate throughout. Length (d 71 ) 

 13.0 mm.; width 6.4 mm. Southern California, Mr. Sanford. 



araneoides n. sp. 



6 Body narrower, more oblong-oval, or less constricted at the waist, 

 opaque; head coarsely, loosely punctate, more coarsely but scarcely 

 more closely basally; prothorax shorter, more parallel and with 

 less inflated sides than in any other form, of the usual convexity but 

 more narrowly declivo-subexplanate at the sides, the surface not 

 impressed medially, coarsely, densely and sharply nuiricato-punc- 

 tate, the basal impression as usual; elytra as wide as the prothorax 

 and about twice as long, nearly as in the preceding but with the 

 granules laterally smaller and sparser; abdomen very strongly, 

 rather closely, muricately punctate, the interspaces rather shining
