HOMALOSILPHA USTULATA Burmeister 



Periplaneta ustulata Burmeister, Handb. Ent., vol. 2, 1838, p. 503. 



One female, Soekaboemi, March 25; one nymph, Buitenzorg, 

 March; two nymphs, Mount Salak, March 7 (2,500 feet altitude). 



These characteristic appearing nymphs are large, the largest being 

 27 mm. in total length; the abdomen is wholly black except the 

 supra-anal plate and the median portion of the venter, which are 

 yellow; legs and basal part of antennae black; thorax yellowish, the 

 disk of the three sections posteriorly margined with black and their 

 disks with maculations of the same color, on the pronotal disk assum- 

 ing the shape of a roughly formed circle inclosing a median longitu- 

 dinal stripe with a spot on each side of it. The pronotal disk differs 

 from that of the adult by being decidedly broadest considerably 

 behind the middle, especially noticeable in the smaller nymph; the 

 maculation on the pronotal disk of the adult is much more reduced 

 than in the case of the nymphs, but there is perhaps considerable 

 variation in these markings.
