DARALA SCHLEGELII. 83 



yellowish sericeous pubescence , on the mandibles however 

 at the base only; the rest of the head with the exception 

 of the highly polished lower angles of the face dull, be- 

 hind the eyes sericeous, which is also the case (although 

 more inconspicuously) on the pronotum, on the sides of 

 the thorax and on the legs ; the meso- and metanotum are 

 dull black, with a trace of a sericeous gloss; the postscu- 

 tellum is divided by a central impression, the metanotum 

 provided with an impressed longitudinal central line which 

 ends in an indistinct circular impression and with more or 

 less longitudinal wrinkles which at the base only are well 

 visible; the careenlike lateral edges are slightly curved and 

 divergent towards the apex; the truncation of the meta- 

 notum shows an impressed central line and is clothed with 

 a dense and brilliant pale golden yellow pile which in- 

 vades also the base of the first abdominal segment. The 

 abdomen is clothed with a dull black pile, with the ex- 

 ception however of the three apical segments where the 

 pile is of an ashy colour; beneath a small patch of seri- 

 ceous pile may be observed on the middle of the segments ; 

 the tip of the apical segment , above as well as beneath , 

 is truncate with rounded angles, and emarginate in the 

 middle. The anterior tarsi , and the tibiae and tarsi of the 

 intermediate and posterior legs are sparingly provided with 

 pale coloured bristles; the apical spines of the tibiae are 

 black. 



A single male specimen from Koetoer (Sumatra), which 

 has been captured in June by Mr. A. L. van Hasselt. 



I have dedicated this interesting insect to the memory 

 of the esteemed Director of the Leyden Museum of Natural 

 History, Prof. Hermann Schlegel , to whom Natural Sciences , 

 and especially Zoology, owe so much.
