1 larva, Kandy, Ceylon (coli. K. Seyd 1908). 



Genus Pelmatosilpha, Dohrn. 

 Pelmatosilpha sinhalensis, sp. n. 



cf. Piceous, nitid. Ocelli and labial palpi testaceous; antennae, 

 maxillary palpi and labrum castaneous. Eyes and antennal sockets 

 equidistant. Pronotum without impressions, posteriorly truncate. Tegmina 

 quadrate, extending lo middle of second abdominal tergite, slightly 

 scabrous, anal vein impressed, tbe other veins obsolete, outer angles 

 rounded. Wings minute. coriaceous. Seventh abdominal tergite slightly 

 produeed in tbe middle. Supra-anal lamina sub-quadrate, posterior angles 

 rounded, posterior border slightly emarginate, rufo-fimbriate, a central 

 carina. Abdomen dark castaneous beneath, sub-genital lamina narrow, 

 a pair of long slender styles. [Cerci missing]. Coxae and femora 

 castaneous, femora strongly spined. Pulvilli large, covering the whole 

 of the distal joints, posterior metatarsus biseriately spined beneath. 

 Total length 20 mm; length of tegmina 6,1 mm; pronotum 7 X 9,8 mm. 

 Ceylon (coli. Freudenberg). 



The relative distances apart of the eyes and antennal sockets is 

 a most unreliable character on which to separate the New World genera 

 of Blattidae with large pulvilli from the Old World genera; I hope to 

 publish shortly a revision of the subfamily Blattinae in which it will 

 be shown that the geographical boundaries of the genera Pelmatosilpha 

 and Eurycotis must be considerably extended. 



Sublam. Corydiiuae.
