 toward the sides of the prothorax ; elytra coarsely, rather sparsely punctured ; 

 male antennal club more than twice as long as wide, the joints very unequal, the

 the first as long as the entire preceding parts, the funicle fully as long as the two 

 basal joints combined ; club of the female much smaller but with the joints un- 

 equal. I.ength 1.65-2.2 mm.; width 0.9-I.28 mm. Arizona (Benson).

Pubescence dark fulvo- or piceo-cinereous and less distinct 17 



17 — Pronotal punctures moderately close-set but very fine, not dense and very incon-

18 — Pubescence fulvo-cinereous, coarser and distinct, moderately dense ; body oval, 

 black or piceous-black, less elongate ; sides of the male pronotum strongly con- 

 vergent and almost evenly arcuate throughout ; antennal club rather dark brown- 

 ish-ferruginous in color, narrowly oval and two and one-half times as long as 

 wide in the male, with the second joint three-fourths as long as the first ; hind 

 tarsi distinctly shorter than the tibiiX. Length 1. 9-2. 25 mm.; width 1.I-1.3 

 mm. Texas (Brownsville) modestum, sp. nov. 



Pubescence finer, piceous and much less distinct ; body black, narrower, more paral- 

 lel ; sides of the pronotum in the male strongly convergent anteriorh-, subangu- 

 larly rounded behind the middle and thence parallel and straight to the base, the 

 edges more widely subexplanate ; antennal club black or blackish, nearlv similar 

 in form in the male but with the joints less unei|ual, the second four tiftlis as long 

 as the first. Length I.7-I.8 mm.; width 1.05-I.15 mm. Texas and Utah

There are a few other apparent species indicated by inadequate or 

 poorly preserved material, and the genus is evidently a large one. In 

 striking contrast to Trogoderma, individuals are abundant when dis- 

 covered, and most of the species are represented by good series. The 

 species fi/sculiim of LeConte, which is entirely valid, is said by Dr. 

 Jayne to inhabit the Atlantic regions ; it is however Sonoran, and was
