238 Mr. F. P. Pascoe's Descriptions of New Genera 



dilated, the first, third and fourth slender, and nearly equal ; pro- 

 thorax uneven, attenuated anteriorly ; elytra subulate, shorter than 

 the abdomen ; anterior legs short, the posterior very long, its 

 femora clavate, tibiae serrated and spurred, the tarsi short. 



Allied to Necydalis, L,, but abundantly distinct in its antennae, 

 elytra, &c. Molorchus Indicus (Hope), Heiiomanes nigriceps, 

 (White), and other undescribed species, belong to this genus. 



Merionceda puella. 

 M. atra ; prothorace luteo ; femoribus basi testaceis. Macassar. 



Black, coarsely puunctured ; prothorax and scutellum reddish 

 yellow ; elytra two-thirds the length of the abdomen, each with a 

 raised longitudinal line near the apex; the shoulders prominent. 



Length 3g lines. 



MerioncBda sc'ilella. (PI. XXV. fig. 3.) 



M. atra ; prothorace luteo ; elytris maculd basali, antennis 

 articulis duobus ultimis, femoribusque posticis basi testaceis. 

 Borneo. 



Black ; prothorax yellow ; elytra along the inner margin, two 

 last joints of the antennae and posterior thighs, at the base, tes- 

 taceous ; in other respects closely resembles the last, but the 

 elytra are more elongate. 



Length 2| to 3| lines. 



Psilomerus ? niacilentus. 



P. elongatus, obscure testaceus ; prothorace elytrisque obso- 

 lete fusco-marginatis, Ceylon. 



Elongate, dull testaceous ; prothorax and elytra with an indis- 

 tinct brown or pitchy stripe externally, and across the base of the 

 latter ; antennae very long. 



Length 5 lines. 



As this genus has never been published, and I have only seen 

 an imperfect specimen of the original species in the British 

 Museum, it is not -without a doubt that I refer this insect to 

 Piilomerus; it is, however, certainly very near it. 



Hemilissa. 



Head broad, very short ; the eyes large, slightly emarginate; 

 aniennffi moderate, the joints subcqiial, compressed, carinate ; 

 tliorax uneven, narrower than the head, longer than broad ; elytra
