34 PELARGODERUS NIGROPLAGIATUS. 



The prothorax has a small but very distinct tooth on 

 each side; on the bare streaks, especially on their basal 

 portion, very distinct transverse wrinkles are present, and 

 the surface of the thorax is sprinkled with a few black 

 points ; a bare longitudinal line divides partially the median 

 pubescent streak. 



The elytra have a large depressed space on the middle 

 of their basal fourth ; they are granulate at the base, especially 

 towards and on the shoulder region , and each granule is 

 generally followed by an impressed puncture ; further on 

 the elytra are covered with punctures which become smaller 

 towards the end; the apices are obliquely truncated, the 

 sutural angle is rounded, the outer one distinctly spined. 



Body beneath and legs sparingly punctured. The inter- 

 coxal part of the mesosternum is slightly raised along the 

 middle and minutely protruding. 



Hah. The eastern part of the Malay Archipelago, — The 

 Leyden Museum has received the here described female 

 specimen, without indication of a more precise locality, 

 from Dr. H. J. Veth. 



The distinctly spined outer angles of the apex of the 

 elytra and the ringed antennae together with the large 

 velvet-black patch about the middle of the elytra make 

 this species easily recognizable from the allied P. arouensis 

 Thoms. 



Leyden Museum, December 1897. 



P.S. The above description was already printed when 

 Dr. Veth communicated to me a male specimen of this 

 species received by him together with the described female. 

 The male agrees with the female except in the sexual 

 characters, viz. less robust shape, longer antennae, elongate 

 anterior legs etc., but the tooth on the sides of the 

 prothorax, which is very distinct in the female, is almost 

 entirely wanting in the male specimen.
