218 ON COLEOPTERA FROM THE TIMOR-LAUT ISLANDS. [Apr. 1 , 



Lam 1 1 D^. 



Tmesisternus glaucus, Pascoe ? 



I am not sure of the identity of Mr. Forbes's specimen with the 

 species described by Mr. Pascoe. It has more yellow colour on the 

 abdomen. 



Hah. Maroe. 



Pelargoderus rugosus, n. sp. 



Nearly black; head coarsely rugose, with sandy yellow pubescence 

 round and beneath the eyes. Basal joint of the antennae very 

 rugose, not much narrowed at its base. Thorax rugose, rather dull, 

 with scarcely any trace of lateral spine, sparingly pubescent; the 

 pubescence forming a narrow sandy line on each side of the middle. 

 Elytra with the basal half rather strongly punctured, those at the 

 base generally marked by a shining granule ; the posterior half is 

 more closely and more rugosely punctured. The basal half and the 

 sides are rather closely marked with irregular small spots of sandy 

 pubescence, but at about one quarter from the base there is near 

 the suture an oblique bare patch. A little behind the middle there 

 is a rather large oblique bare patch, which extends from the side to 

 the suture ; and behind this there is a patch of pale sandy pu- 

 bescence, not quite touching tlie side, but reaching the suture and 

 the apex. The apex of each elytron is obliquely truncate, the outer 

 angle obtuse. 



Length 18 lines. 



Hab. Larat. 



This species is very close to P. arouensis, Th., but is more 

 robust, much more rugosely sculptured on the head and thorax; 

 and the basal joint of the antennae is less narrowed at the base and 

 more rugose. 



Nemophas roRBESi, n. sp. (Plate XVI. fig. 5.) 



Black, with the elytra bright steel-blue ; the thorax entirely 

 clothed with sandy yellow pile ; the elytra with numerous more or 

 less interrupted bands of reddish ochreous pubescence. 



Length 1 7-20 lines. 



This species is close to N. grayii, Pascoe, but has no trace of 

 blue colour in the head and antennae. The thorax is entirely 

 covered with the yellow pile, with no black at the base. The bands 

 of the elytra are more numerous, generally about seven, and these 

 are more irregular. And lastly, tlie sterna, epimera, and the basal 

 segments of the abdomen are more or less clothed with reddish 

 pubescence. 



Hab. Maroe and Larat. 



Batocera rubus, Fabr., var. ? 



The specimen from Larat is a little larger than B. rubus usually 

 is, and has the scutellum clothed with fulvous instead of white 

 pubescence.
