 OLENECAMPTUS Q.UIETUS. 



O. luteus, supra pube flavescente dense tectas, infra niger, nitidus, 

 interrupte albido pubescens ; antennisfuscis. 



Luteous, with a closely set yellowish pile above, beneath glossy 

 black, the propectus, sides of the postpectus, and abdomen with a 

 whitish pile ; head nearly impunctate ; prothorax scarcely longer 

 than broad, not corrugated ; scutellum semicircular ; elytra with 

 the sides nearly parallel at the basal half, then slightly diverging until 

 towards the apex, where they are rounded off; the apex itself of each 

 slightly truncate, but scarcely mucronate ; legs glossy brown, the 

 tibiae and tarsi of the fore and intermediate legs luteous ; antennae 

 brown, not scabrous. Length 5 lines. 



Of this new and very distinct species there is only a single example 

 in the collection.

Atossa atomaria. (PI. XXVI. fig. 6.) 



A. fuscescens, nitida, pube sparsa tecta ; capite prothoraceque 

 Jiavo vittatis ; elytris seriatim albido maculatis ; lateribus infra 

 etfronte capitis albidis. 



Pale brown, with a thin pubescence ; head pale greyish in front, 

 forehead, behind the eye, and vertex brown, the latter impunctate, 

 with two yellowish longitudinal lines corresponding with two on 

 the prothorax, a similar line also on each side, disk of the prothorax 

 very slightly punctured ; scutellum transversely scutiform ; elytra 

 finely punctured, speckled with numerous clear greyish pubescent 

 points arranged to a certain extent in longitudinal lines ; body beneath 

 dark chestnut-brown, shining, with a sparse silvery pubescence, which 

 is dense along the sides of the breast ; legs and antennae with a pale 

 greyish pile, the latter about two-thirds the length of the body. 

 Length 6 lines. 



A. strenua, M. J. Thomson's type, is from Java. The present 

 species has the elytra finely but very distinctly speckled with greyish, 

 and the front uniformly greyish, except the space in a line with the 

 antennary tubers.

Nyctimene agriloides, J.Thomson, I. c. 



Not uncommon apparently in the Malayan region. M. J. Thom- 

 son has placed this genus in a " groupe" to itself, as it differs from

 the base. I do not think, however, that it would be natural to sepa-
