THE CANADIAN ENTOMOLOGIST 273 



ON SOME CENTRAL AMERICAN DERMAPTERA IN 

 THE UNITED STATES NATIONAL MUSEUM. 



BY MALCOLM BURR, D. SC, LONDON, ENGLAND. 



The following notes form a list of a number of Central 

 American Dermaptera submitted to me for study. Although 

 there are no species new to science among them, some of the 

 records of scarce and little known species are of considerable 

 interest. 



Diplatys jansoni, Kirby. 



Panama — Canal Zone, Paraiso, 5. ii. and 7-10. v., 1911, 2 o 71 ; 

 8-9. ii. and 22. iv., 1911, 4 9 9 ; 5. ii. and 1. v.. 1911, 2 larvae 

 (Schwarz) . 



It was formerly suggested that D. sever a Borm. was a mere 

 melanic form of this species, but the two are undoubtedly dis- 

 tinct. It is desirable that the genital armature of the American 

 Diplatyinae be examined, for which purpose material in alcohol is 

 urgently needed. New genera will probably be required for this 

 and the following species. 



Diplatys jansoni superficially resembles a staphylinid beetle. 



Diplatys gracilis Sta.1. 



Panama — Canal Zone, Porto Bello, 20. ii., 1913. o 71 . (Schwarz.) 

 This species has not hitherto been recorded from Central 

 America, but only from Peru and Brazil. It is a rare insect in 

 collections. I consider D. sahlbergi a mere variant. 



Pyragra fuscata Serv. 



Mexico — Omealca, V. C. 16. iv., 1908. 9 and larva. (Knab.) 

 Guatemala— Dept. Solola, Olas de Moka, 3000 feet., ix., 1908. 

 2 larvae. (Engelhardt.) 



Echinopsalis guttata Bonn. 



Panama — Porto Bello, 25. ii., 1911, and Paraiso, 17. i., 1911, 

 both larvae. (Schwarz.) 



Recorded from Nicaragua, Costa Rica and Colombia. It is 

 a rare species. 



August, 1914.
