232 AEGUS CAPITATUS. 



and 4 th moreover coarsely punctured at the basal portion; 

 beyond the 5 th interstice as well as at the end the elytra 

 are rugose in consequence of a very dense and confluent 

 sculpture, with the exception of two narrow costae origi- 

 nating from the shoulder (the inner one much more dis- 

 tinct) and the apex of the sutural interstice which are 

 smoother; the shoulders are pointed, the outer margin of 

 the elytra minutely crenulate, and the striae and rugose 

 portion provided with short erect fulvous hairs. 



The under surface and legs sparsely covered with short 

 erect fulvous hairs; the jugulum and mentum shining and 

 covered with large and deep punctures which are wider 

 apart on the jugulum; on the basal portion of the latter 

 a narrow but deep transverse furrow occurs in the small- 

 est specimen (that from Serdang). The lateral portions of 

 the head are very shining and show a few large punctu- 

 res; the base is finely rugose as well as the middle of 

 the prosternum , the sides of which are , however , very 

 shining, nearly impunctate; the centre of the metaster- 

 num is finely and distantly punctate, the rest shows a 

 somewhat reticulate sculpture; the epipleural fold of the 

 elytra has an indistinct reticulate sculpture. The abdomen 

 is rather strongly and equally punctured ; the lateral mar- 

 gins of the 2 nd and following segments are thickened 

 and glossy, widened out on the last segment where this 

 margin is notched at the apex. The anterior tibiae are 

 serrated along the outer margin , the intermediate and 

 posterior ones armed with two spioes, one about the 

 middle, the other (the smaller one) between the middle 

 and the base. 



Aegus capitatus Westw. is as yet recorded as inhabiting 

 Malacca , Prince of Wales' Island , Sumatra , Banca and 

 Borneo , whereas the allied Aegus labilis Westw. (? paral- 

 lelus Hope) , a species known to me by description and 

 figure only, originates from Darjeeling.
