138 AMERICAN COLEOPTERA. 



The most notable variations from the typical form occur in 

 color, which is often paler, the larger eyes and the shorter 

 elytra, which may be more narrowed apically. The follow- 

 ing is a very distinct species. 



P. megalops n. sp. 



Reddish-brown, form strongly elongate, elytra nearly parallel, about 

 three and one-fourth times as long as wide ; pubescence very short ; 

 eyes very large and prominent, their width, viewed from the front, fully 

 two-fifths the interocular width. Length, 12-13 mm. ; width, 2.8-3 mm. 



Pomona, California. 



The above characteristics are sufficient and perfectly dis- 

 tinctive. The prothorax varies as usual in form, the sides 

 either straight or more or less dilated at middle ; the punc- 

 tuation variable but never very coarse or dense. The hind 

 angles are always strongly divergent. 



Numerous specimens have been taken in years past, and 

 have been sent to correspondents as Schaumii. I have never 

 seen it from any other locality, and suspect it to be very 

 local or restricted in distribution. 



BUPRESTID^. 

 POLYCESTA Sol. 

 P. obtusa Lee. 



The type has a dense brush of yellowish hair on the first 

 ventral segment, indicating that it is really atigulosa and not 

 velasco as recorded in synonymy. The first ventral segment 

 is scarcely or but slightly swollen and is as densely punctate 

 as the other segments. 



AGRILUS Steph. 

 A. knausii Schf. 



Typical specimens of this species were sent me by Mr. 

 Knaus several years ago. They were at first thought to be 

 new, but on comparison with the type of obolinus at Cambridge 

 I came to the conclusion that they were not specifically dif- 

 ferent. Since Mr. Schaeffer's description of the species under 

 the above name I have again compared my specimens with 

 the LeConte type, and see no reason to reverse my first deci- 

 sion. The diagnosis of obolinus as given by Horn in his
