E. tscliivavensis, Hald., Stansb. Rep. Salt Lake, 371, PI. x, Fig. 3. 



Robust, dull-brown, beneath yellowish; head rough; antennse deep set, 

 filiform, shorter than the pronotum, inserted opposite the lower canthus of 

 the eyes, upon each side of a double vertical frontal carina ; labrum transverse, 

 and with the palpi flavous. Pronotum ample, coarsely scabrous, blackish, 

 changing to yellowish posteriorly. Elytra and wings rudimentary, the former 

 gray, mottled with black. Inside of the posterior femora and tibiae black, the 

 former interrupted near the apex. The posterior tibiae have a row of spines 

 upon each side above. 



9 Length, 1.25 inche.s; antennae, 0.5 inch ; pronotum, 0.58 inch; elytra, 

 0.33 inch; posterior femora, 0.58 inch; posterior tibiae, 0.58 inch. 



Chihuahua (Plaldeman). 



Remarks. — The shape of the pronotum is that common to the pupae of 

 that subdivision of Q^dipoda to which CE. corallipes belongs; the color as de- 

 scribed is also very much the same ; the inside of the posterior femora, it is 

 true, is black, but this is not rare ; at least, the pupae, in this respect, seldom 

 correspond with the perfect insects. Haldeman's figure shows his specimen 

 was an immature female; the posterior femora show plainly the Qildipodoid 

 type. 



Note to O. PUNCTiPENNis, 'page 64. — My Opsomala punctipennis, (Trans. 

 111. State Agl. Soc, vol. 5, p. 447), I am now satisfied, is a misnomer. I have 

 no specimens remaining, all having been destroyed several years ago; but, 

 from my description and memory, I am now inclined to believe they belonged 

 to Pyrgomorpha punctipennis, Thos. 



Page lb. — Add as a synonym to C. viridis the following: Opsomala 

 brevipennis, Thos., Trans. 111. State Agl. Soc, vol. 5, p. 451. 



Pages 195-196. — O. varipes, O. puncfijMnnis, and O. marginicoUis 

 have been inadvertently inserted here as well as in Part I (see pages 64, 

 65 and 66) ; they are given as belonging to the United States fauna on the 

 authority of De Haan, which I consider as doubtful. 



Page 200. — Hippiscus ought probably to be placed in the vicinity of 

 Stauronotus.

Has been uninteuti'onally omitted. It is very similar to B. magmis, a 

 little smaller and uniform green. Mexico (Charpentier)..
