The O. U. M. has several specimens each from Java, from Sarawak 

 (Shelford), from Kalim Bungo, Nias (R. MlTSCHKE, 1896), and one example 

 from the Philippines (WALLACE). I took this species once only on the Malay 

 Peninsula (Bukit Kutu, Selangor, April 1915). 



Distribution: Malay Peninsula, Sumatra, Nias, Java, Borneo, Philippines.

The place of origin of the type (cf ) was given by BRUNNER doubtfully 

 as "Java?" Both cfc/ and î^ gave since repeatedly been recorded from Java, 

 and also from the Malay Peninsula, Singapore, Sumatra and Borneo. The 

 O. U. M. has a long series from Sarawak. 



BRUNNER gave the following dimensions: d": body 15 mm; tegmina 

 22 mm; pronotum 3.7X5 rnrn« This is exceeded by the largest cf in the O. U. 

 M., from Sarawak: body 19 mm; tegmina 27 mm; pronotum 7 5X8 mm. 



The 2 shows similar variation in size, Saussure ') who described this 

 species under the name of Archiblatta valvularia, from Java, gave the 

 following dimensions: body 20 mm; pronotum 4.7X7.3 mm. The largest 

 $ in the O. U. M., from Sarawak, measures: body 23.5 mm; pronotum 

 8X12 mm; and this is exceeded by the largest +, from Borneo, in the 

 present collection, viz. body 25.5 mm, pronotum 9X12 mm. 



The two sexes show a striking difference, the o^ being slender, deli- 

 cate and long-winged, the + short, stout and entirely apterous. The c;^ was 

 sufficiently described by BRUNNER. The 9 may be characterised as follows: 



$. Entirely apterous. Dull black, with the exception of the eyes which 

 are light brown. Head covered. Pronotum parabolic, lateral margins 

 raised and posteriorly produced into heavy spines, its surface corrugated, 

 deeply pitted with dots. Mesonotum and metanotum also deeply pitted, but 

 less corrugated. Abdominal tergites uneven, not pitted, their posterior 

 margins granulated. All femora entirely unarmed. Anterior tibiae along their 

 iiuier aspect covered with a dense brush-like mass of russed-coloured 

 hair; beyond this brush, towards the upper aspect of the tibiae, a few 

 (about 5) spines; median and posterior tibiae with two rows of about 4 

 spines each. 



In smaller, i.e. probably younger, specimens we find distinct spines 

 instead of the granulation along the posterior margins of the abdominal
