 joints distinctly diluted, forming u club, the ninth und tenth strongly truns-

Prolhora.v quudrale, very neurly as long us wide; diac just visibly wider 

 at apical third than at base, evenly convex, externally, minutely, and sparsely 

 punctate; apcjc transverse, broadly und feebly bisinuate, equal in width to the 

 base; sides parallel, very feebly arcuate; base broudly and ruther strongly 

 arcuate; apical angles right, narrowly rounded; busal angles broudly obtuse 

 and not prominent nor at all rounded. 



Eliifra two and three-fourths times as long us the prothorux, und in the 

 middle neurly one-half wider, ubout twice as long as wide; base broadly emar- 

 ginate ; hmnvrl iMglit, not noticeably exi)osed ; .s/'/r.s- broadly arcuute; upex 

 acutely rounded; dhv obliquely declivous behind, having feebly marked, distant, 

 completely unimpressed series of extremely minute punctures; intervals mi- 

 nutely, sparsely, and more or less confusedly punctate, the punctures not 

 distinctly larger or denser laterally. 



Femora all slender and completely unarmed ; spurs of the anterior tibi;e 

 very unequal, the anterior slender, acutely pointed, and moderate in size; 

 posterior tarsi slightly compressed, nearly three-fourths as long tis the tibite. 



I'rosternum slightly prolonged but not at all reflexed, the apex vertical. 



Length, 18 mm. ; Avidth, G.7 mm. 



Habitat. — Arizona. 



Case3''s specimen was a unique and he compares it Avith loiiy'tcoJUs. 

 He Avrites that it ditl'ers from that si)ecies in its Hatter, rather shorter 

 prothorax, AAdiich is less roinided on the sides, and in its shorter, 

 Jn'oader elytra, broadly and rather strongly emarginate at the base 

 and liaA'ing widely distant roAvs of punctures, and in having a shorter, 

 stouter, and much more claA'ate antenna\ 



It is possible that the species described by me as dissimUis may be 

 nitidus. Dissitn'diii is A^ery A'ariable. (See ]). 398.) 



ELEODES REFLEXICOLLIS Mannerheim. 



I haA^e failed to satisfactorily place this species of Mannerheim's, 

 the type of Avhich AA^as taken at Ross, California. This locality is 

 undoubtedly Fort Ross, near the mouth of the Russian RiA'cr on the 

 coast. 



Maunerheim says that it is close to EUodcs phmata Eschscholtz, 

 and that the sides of the thorax are unusually reflexed, and the base 

 abru[)tly narrowed. Pecidiar and aberrant foi-nis are occasionally 

 met Avith. (See scahricula for remarks upon a unique specimen 

 taken in Napa County. California, and in tlie collection of A. 

 Koebele.) 



FATILY STAGFS OF TIIF Er^KODIINT. 



Comparatively little has been written upon the early stages of the 

 TenebrionidcT of the United States, and also little upon the tribe.
