base of the elytra as in the species mentioned, also the discal and sub- 

 apical spots are constantly smaller and regularly circular, ventral sur- 

 face black except that portion of the reflexed margin of the elytra 

 occupied by the marginal vittae. Form regularly oval ; head very 

 sparsely and minutely punctured; pronotum a little more heavily and 

 thickly punctured; scutellum large with a few coarse punctures; elytra 

 more thickly punctured than head, but less thickly than pronotum ; 

 ventral surface with mesosternum smooth, episternum of mesothorax 

 very coarsely punctured. Head of $ chrome yellow, the anterior bor- 

 der of the pronotum narrowly, and the lateral borders heavily mar- 

 gined with the same color, the lateral margin not quite reaching the 

 base, anterior pair of legs and tarsi of all yellowish. 



$ . Entirely black except elytral markings, tarsi dark fuscous. 



Length. $ 2.5 mm., $ 3.1 mm. 



Width. $ 1.7 mm., $ 2.1 mm. 



Type $ $ and five cotypes, one $ and four $ $ , in my 

 collection. 



Type locality Goldfield, Esmeralda Co., Nevada, vi. 27. 07 

 (Nunenmacher). 



In general form and markings the specimens are remark- 

 ably constant. I have many times bred lateralis and the larva 

 of wellmani is strikingly different from that species. The fol- 

 lowing table will aid in separating the adults : 



1. (2) Marginal vittae broad, not increasing posteriorly, episternum of 



mesothorax mediumly punctured, foveae for reception of 

 hind tibiae rather shallow, size large and form more convex 

 than the following species lateralis 



2. (i) Marginal vittae narrow, distinctly increasing posteriorly, epi- 



sternum of mesothorax very coarsely punctured, foveae for 

 reception of hind tibiae deep, size smaller and less convex 

 than preceding species wellmani 



Hyperaspis wolcotti n. sp. 



9- Color: Head, pronotum and scutellum black, the pronotum with 

 rather wide stramineous lateral margins, elytra piceous with stramine- 

 ous markings arranged as follows : A wide marginal, strongly sinuous 

 vitta extending from the humeral angle of each elytron to a point near 

 the suturoapical angle ; for about its posterior third, this vitta does not 

 entirely reach the margin of the elytron ; a narrow edging of the elytral 

 ground color appearing outside of the vitta ; the apical end of the vitta 

 is constricted near the extremity tending to form an apical spot ; a sec- 

 ond straight juxta-sutural oblique vitta extends from the base of the 

 elytron to about two-thirds its length, the obliquity being from near
