first much stouter than the second and clothed with stiff sparse seta; 

 throughout, this being a very remarkable feature.

Additional Notes and Synonymy. 



Ftinodes cristatus Csy. (Col. Not. II, p. 323) should be referred 

 to the genus Trichodesma ; it is much stouter than the eastern species. 



Comonfellus suhglaher Csy. (1. c, p. 389), should be united with 

 obe.ms Lee. 



Eleodes taisalis Csy. (1. c, p. 399), is without doubt the species 

 intended by Mannerheim as quadricoUis; the female is frequently 

 altogether devoid of the series of coarse punctures, and the original 

 type of tarsalis has a singular bilaterally symmetric deformity of 

 the posterior tarsi. I have before me a large series. The single 

 specimen referred to quadricoUis (1. c. p. 395)' is either a closely 

 allied species with coarser pronotal sculpture, or a simple aberration. 

 Estriatus is a widely distinct species, also represented by a large 

 series. 



Argoporis nitida Csy. (1. c, p 405), has been erroneously referred 

 by Mr. Champion (Biol. Cent.-Amer., Coleop., lY, i, p. 518), to 

 rvjipcs Chmp. A male of the latter species kindly sent me by the 

 author, shows that rvfipes is a stouter and much duller species, with 

 smaller punctures of the elytral series, and differs greatly in the 

 structure of the anterior legs in the male. In the male of rvfipes 

 the anterior femora are stouter, with a much less developed internal 

 subbasal dentiform lamina, and the corresponding tibiae have onl}' 

 five or six widely spaced granuliform serrules internally, while in 

 nitida the internal cariniform elevation of the femur is very pro- 

 nounced, and the tibiae are finely and closely serrulate within through- 

 out the length ; the last joint of the anterior tarsi in nitida is rela- 

 tively longer, nearly equalling the three preceding combined. 



The reference made (Col. Not. Ill, p. 21, footnote), to a single 

 mandibular tooth in Ergates neomexicanvs is not exactly correct, 

 as I find by prying the mandibles further apart ; the basal tooth is 

 hewever more feeble than in i^jncKlatus. The proper status of 

 neomexica,nus is probably tliat of a well-marked variety of spiculatiis. 

 All the specimens which I have seen have large pallid blotches on 

 the elytra; whatever may be the cause of these blotches, they are 

 completely wanting in my two specimens of s2jirulafus.
