ASV0.4TES n. gen. 



This genus dirters but slightly from Trichochrous. but the 

 smull prothomx and broad subdepressed el^'tra, which are nar- 

 rowl}^ reflexed at the sides, give to the two species which at pres- 

 ent compose it, a facies which is quite peculiar and distinctive ; 

 the general habitus is in fact intermediate in some respects be- 

 tween Trichochrous and the genera allied to Allonyx. The epi- 

 pleuraj are broad and Hat, and this character distinguishes it at 

 once from Trichochrous, although in other structural features it 

 is virtually similar. The epipleur;\? are relatively altogether as 

 as wide as in Eudasytes, or even wider; the\' do not, however, 

 follow the apical curve of the elytra as in that genus, but become 

 abruptl}' obsolete at a greater distance from the apex. The spe- 

 cies are mutualh^ verA' distinct in appearance and ma}- be thus 

 distinguished : — 



Pubescence coarse aud rather dense, not intermingled AWtli erect hairs; abdomen 

 entirely red 1 ruflreiitris 



Pubescence fine and very sparse, intermixed with short but inconspicuous 

 erect hairs; abdomen red, blackish near the base 2 explaiiatiis 



It is probable that this genus is local and confined to the coast 

 regions of California near Santa Barbara and Los Angeles, a 

 faunal region which is known to support a considerable propor- 

 tion of endemic forms. 



1. A. ril fiTeiitriSi n. sp. — Oblong, sulioval, broad and subdepressed, 

 black, with a strong teneous lustre; elytral apices, abdomen and legs through- 

 out jjale rufous; antennae darker, testaceous, blackisli toward apex; integu- 

 ments strongly shining; pubescence rather coarse, long and somewhat dense, 

 closely decumbent, pale fulvous and \erj conspicuous, without trace of inter- 

 mixed erect setae; marginal cilia short, dense and fimbriform, longeron the 

 elytra. Head two-thirds as \\ ide as the prothorax, nearly smooth, a ery obso- 

 letely reticulate, finely, sparsely i)unctate; impressions feeble and widely 

 separated; epistoma very sliort and broad: hibrum short, subtruncate at apex; 

 eyes large but not prominent, nearly attaining the base; antenna; but little 

 longer than the prothorax, feebly serrate, slightly incrassjite, the penultimate 

 joints transverse. Prothorax three-fifths wider than long, widest just visibly 

 ])ehind the middle, the sides subparallel and stronglj' rounded ; apex arcuato- 

 truncate, slightly narrower than the base; all the angles very obtuse and more 

 or less rounded; disk finely, sparsely punctate, the intei-si«ices smooth, not 

 rugose laterally. Elytra scarcely two-fifths longer than wide and nearly one- 

 half wider than the prothorax, the sides subparallel and nearly straight: apex 

 almost evenly and not ol>tusely rounded; humeri broadly exposed at base;
