what ill a transversely sinuous excavation. Last joint of the 

 maxillary palpi rather small, right-angled, of the labial unusually- 

 large, strongly transverse, with the deeply concave oval apex 

 pilose. A.ntennffi filiform, moderate in length. Middle coxa3 nar- 

 rowl>^, the posterior rather widely, separated. Basal segment of 

 the abdomen larger than the remainder, with scarcely a trace of 

 the dividing suture. Legs slender, the hind femora not dilated, 

 simple beneath, the tarsi short, with the basal joint abbreviated 

 and much shorter than the remainder. 



Our single species of this distinct geuus, erected by Mr. Cham- 

 l)ion (Biol. Cent.-Amer., lY, 2, p. 460) for the minute Mexican 

 G. Jlohri is the following : — 



1. C. iiupressu!;! Lee. — Trans. Am. Ent. Soc, 1875, p. 175 (Xylopbiliis). 



Piceous, shining, sparsely pubescent. Head polished, convex, 

 finelv, not densely- and indistinctly punctate ; antennae one-half 

 as long as the body. Prothorax transverse, with two deep sub- 

 basal impressions which are feebl}^ connected transversely, finely, 

 rather strongly and moderately closely punctate. Scutellum short 

 and wide, small, in the form of a perfect parallelogram. Elytra 

 oblong-oval, scarcely one-half longer than wide, nearl}^ twice as 

 wide as the prothorax, finely but strongly, not very densely punc- 

 tate. Abdomen alutaceous. Length 1.] mm.; width 0.4.5 mm. 



Texas, — Cab LeConte ; Florida. This species differs from Jiohri 

 in its much shorter antenna^, which, in the latter, are said to be 

 three-fourths as long as the body. Excepting AxylopMlus yuccae, 

 this is by far the most minute xylophilide thus far discovered in 

 the United States ; it probably occurs on maritime plants along 

 the shore line of the Gulf of Mexico.

The complete lack of a basal cephalic constriction, which ren- 

 ders this and the following two genera so aberrant, is somewhat 

 suggested in Cnopus, where the constriction is carried forward, 

 leaving the basal part of the head on a level with the pronotura. 

 The body is very obese and convex, clothed with a short coarse 

 decumbent and matted i)ubescence, variegated in color and inter- 

 mixed with sparser, semi-erect hairs arising from the larger punc- 

 tures. Head vertical or slightly inflexed, broadly arcuate at base,
