EUPOGONIUS Lee. 



Four species are known to inhabit our territory. 



Lateral spine of thorax acute, well marked 2. 



Lateral spine of thorax small, obtuse 3. 



2. — Elytra pale castaneous, the punctuation not strong, almost obliterated near the 

 apex, the pubescence cinereous or yellowish forming reticulations more or 



less transverse touientosus. 



Elytra piceous, the punctuation coarse gradually finer but not obliterated at 



tip, the pubescence luteous arranged in irregular small patches..vestitlis. 



'.\. — Elytra nearly black, the punctuation rather coarse, finer at apex but distinct, 



the pubescence cinereous, fine and verj' evenly disposed ; thorax sparsely 



evenly pubescent pubesceiis. 



Elytra black, coarsely punctured even to the apex, pubescence black and in- 

 conspicuous; thorax with a lateral broad line of yellowish pubescence. 



stibarniatus. 

 In addition to the recumbent pubescence mentioned in the above table 

 the entire bod}', antenna? and legs have short erect hair. E. suharmahm 

 has great resemblance in aspect to our spscies of Amphionycha.

DYSPHACA Lee. 



D. bicolor n. sp. — Pale reddish yellow, elytra, antennae and tarsi pieeous. 

 Head coarsely and rather closely punctate. Thorax as wide as long, sides slightly 

 arcuate, disc moderately coarsely punctate, the punctures indistinct, shallow. 

 Scutellum pale. Elytra a little wider at base than the thorax, extending to the 

 middle of the abdomen, dehiscent, gradually narrower to the apex which is very 

 obtuse, disc of each indistinctly bicostate the surface punctate-scabrous, but 

 smoother near the base. Length .30 inch: 7.5 mm. 



In the specimen before me the antenna; are about one and a third 

 times the length of the entire body and the last ventral segment deeply 

 incised, the incisure fimbriate with short hairs. The specimens with the 

 last ventral segment so found, or as Dr. LeConte expresses it " triangu- 

 larly excavated," were considered by him to be females, and probably 

 correctly, although the specimens of all the species known to me do not 

 exceed five, three in the cabinet of LeConte and two in mine, and give 

 but little ground for the expression of a positive opinion. 

 One specimen from Texas given me by Mr. F. G. Schaupp.
