76 PROCEEDINGS OF THE NATIONAL MUSEUM vol, i04 



H. L. Parker; Giiemes, Salta, Martinez; Rio San Javier, Santa F6, 

 Bryant (type locality of D. nigrosuturalis Bryant); Maza, "F. C. S.," 

 Aravena, Buenos Aires. 



Remarks: In the Museum of Comparative Zoology is a drawer of 

 specimens with the note "16 types of Harold material collected by 

 Davis, sent by Hagen to Dohrn, sent by Dohrn to von Harold who 

 published in the Coleopterologische Hefte, 1875, pp. 95-1 OG." In 

 this are 8 specimens labeled D. caustica Harold. In the Bowditch 

 collection are two others, evidently of the same series, the 

 first labeled type, from C6rdoba, Davis (2nd Jacoby collection), 

 the second with the same label; also one from Bolivia (2nd Jacoby 

 collection), and another from Paraguay, Dr. Bolds. Two of those 

 in the Davis drawer have interrupted elytral vittae such as Bryant 

 described in D. nigrositturalis, in which the median elytral vittae are 

 interrupted with only traces. I have dissected both forms and found 

 the aedeagi alike.
