ACJEtOCRYPTA.

punctate, the punctuation being less distinct than that of the 

 elytra. Smtellum triangular, with apex pointed and surface 

 im punctate. Elytra very convex, slightly widened behind the 

 middle, more distinctly punctate than the prothorax, the punc- 

 tures very closely and evenly placed throughout. Underside very 

 thinly covered with fine hairs; epi pleura broad at base and much 

 narrowed towards apex ; other structures as under the descrip- 

 tion of the genus. 



Length, 5-6| mm. 



Burma: Palon, viii-ix (Feci). 



Type probably in the Genoa Museum. There are two examples 

 in the British Museum from the same locality, with Fea's labels, 

 one being also marked "type." On the libels bearing the name 

 of the insect Jacoby indicates the genus as Sphazroderma, but his 

 published description is under the genus Sphcerometopa. This 

 species, however, cannot be placed in either of these genera, 

 because it has its anterior coxal cavities closed behind, while 

 in the genera Sjnhceroderma and Sphcerometopa they are open. 



123. Acrocrypta momeita*, sp. nov. 



Body broadly ovate and convex. Colour dark reddish-brown, 

 with the antennae and legs black, and the head and pronotum 

 bearing obsolescent black patches in the middle. 



Head finely punctate, frontal elevations flat. Antennae short, 

 passing a little distance beyond the base of the pronotum, much 

 thickened and slightly flattened gradually from the fourth segment 

 onwards; first segment elongate, club-shaped, second small, 

 shorter than third ; the six apical segments covered with bristles, 

 the last small and pointed. Prothorax much broader than long, 

 front margin straight, front angles thickened, sides short and 

 rounded, hind angles drawn forward, as is typical in this genus, 

 and slightly thickened, basal margin gently sinuate on either side, 

 the thickened angles having pores bearing setae; surface convex 

 from side to side, very finely punctate throughout. Scutellum 

 large, triangular, with apex rounded and surface smooth and im- 

 punctate. Elytra broader at ba>e than prothorax ; humerus 

 convex, rounded ; surface confusedly and finely punctale through- 

 out ; in this species the elvtral pun -lures are finer than in 

 A. assameasis, Jac. ; along the marginal area on each elytron the 

 punctures are arranged in three rows: oae lies along the extreme 

 margin, while within this is an interspace, I roader near the base 

 and narrower towards the apex ; internal to the interspace are 

 two parallel rows, placed closed to each other; this interspace 

 and another, arising rather indistinctly behind the humerus, 



* Although the modern spelling of the place in Burma from which this 

 species takes its name is Momeik, the name momeita has been formed from 

 the old spelling Moineit, by which the locality was known in the days of the 

 collector Doherty.
