ides is somewhat allied, but differs in its much more oval form and 

 smaller prothorax. 



32 H. inquilimis n. sp. — Oblong-oval, moderately convex, rufo-testa- 

 ceous, the elytra still paler and more fiavate ; upper surface polished, the 

 pronotum feebly alataceous ; pubescence rather sparse, semi-erect, coarse, 

 tlavate in color. Head decidedly large, strongly, longitudinally convex, 

 minutely, excessively sparsely punctate, the epistoma abruptly flat and more 

 closely but still sparsely punctate ; eyes small, separated by distinctly more 

 than their own width ; antennae stout, cylindrical, nearly one-half as long as 

 the body, distinctly attenuate, the joints obconical, third and fourth equal. 

 Prothorax short, twice as wide as long, the apex subtruncate, just visibly 

 arcuate, three-fourths as wide as the base, the latter broadly arcuate in the 

 middle, the lobe extending posteriorly fully as far as the angles; sinuations 

 extremely feeble ; basal angles right ; sides broadly arcuate throughout, a 

 little more convergent anteriorly ; disk slightly wider behind the middle than 

 at base, feebly explanate near the sides toward base, not distinctly impressed 

 or foveate, very finely ; densely punctate, the punctures distinctly separated. 

 Elytra fully three times as long as the prothorax, and, throughout, slightly 

 narrower than the disk of the latter, distinctly dehiscent in apical third, the 

 two bases exactly equal ; sides parallel and nearly straight, the apex some- 

 what obtusely ogival ; disk rather finely, moderately closely punctate, with- 

 out trace of impressed lines except the sutural, which is very feeble, without 

 trace of punctured series except extremely indefinitely toward base. Abdo- 

 men finely, moderately closely punctate, the fifth segment almost completely 

 impunctate. Legs short and very robust, the tarsi short ; basal joint of the 

 posterior as long as the remainder. Length 4.5 mm. ; width 1.8 mm. 



California. 



The single specimen before me is a male, and differs so greatly 

 from the usual forms in general appearance, that for a long time I 

 thought that it would have to be considered the type of a distinct 

 genus; but, on close examination, no character of any kind can be 

 discerned by which to distinguish it from Hymenorus. 



The maxillary palpi are of the usual form, and the lateral sub- 

 apical emarginations of the fifth ventral segment are deep and dis- 

 tinct. The claws are rather short and stout and finely, closely 

 pectinate nearly throughout the length. This species is said to be 

 myrmecophilous. 



33 H. flisicornis n. sp. — Oblong, parallel, rather robust and feebly 

 convex, piceous above, the elytra black ; under surface and antennae dark 

 piceo-castaneous, the legs paler and more flavate ; lustre rather shining, the 

 pubescence somewhat dark, fine and sparse, rather long, subrecumbent. Head 

 rather large and convex, the epistoma abruptly fiat, very finely, sparsely 

 punctate throughout ; eyes moderate, separated by their own width ; antennae
