Notes on Derobrachus and Acanthocinus. 

 By C. Schaeffer, New York. 

 The description of Z>^w(5rar///^^ybrr<?r/ Bates, Biol. Cent. Am., 

 vol. V, p. 230, fits well the examples seen from lower California, 

 which pass very likely in many collections as D, gevmiatus Lee. 

 My attention was called to this species by a specimen in the 

 Edwards collection, Am. Mus. Nat. History, which came from 

 Dr. Horn and was labelled D. geminatus. Although a very 

 small specimen, the distinctness of this species on comparison 

 with the true geminatus was quite obvious. Forreri differs 

 ixo\\\ geminatus in the more approximate eyes, narrower neck, 

 antennal joints longer and more slender, especially the first 

 three or four joints, the bispinose ^ elytra and the tibiae 

 longitudinally sulcate on the upper as well as on the outer 

 side. The characters mentioned are all constant in the very 

 large series I have seen, and which were mostly all collected 

 by Mr. G. Beyer last year.
