240 MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. [May 8 



cent, scarcely fimbriated ; scape obconic, third joint much longer 

 than the fourth, the rest very short. Prothorax a little broader 

 than the head, subcylindrical, toothed anteriorly. Elytra elongate, 

 cylindrical, callous at the base. Legs short, equal ; anterior tibiae 

 not toothed internally. Prosternum elevated. Mesosternum toothed 

 anteriorly. 



The presence of a prothoracic tooth, as well as the style of sculp- 

 ture, places this genus in the neighbourhood of Synelasma, from 

 which, however, it abundantly differs in the characters of the head, 

 antennae, and in its elongate cylindrical form. 



Cyardium cribrostjm. (PI. XXVI. fig. 5.) 



C. pallide ferrngineum, sparse griseo pubescens ; elytris post me- 

 dium fascia albida ornatis ; antennis articulis tertio et quarto, 

 apice excepto, albis. 



Pale rusty brown, rather sparingly clothed with a greyish pubes- 

 cence ; head deeply impressed on the vertex between the upper 

 lobes of the eyes, the front coarsely punctured, each puncture with 

 a stiff whitish hair at the base ; prothorax with deep crowded irre- 

 gular impressions having apparently a deciduous greyish pubescence, 

 the raised intermediate portions tuberculiform or granular ; scutel- 

 lum very transverse ; elytra with a slight callus near the base, and 

 numerous large foveolate punctures, and little patches of ochreous 

 pubescence between them, behind the middle a broad whitish band ; 

 body beneath pale buff, spotted with yellowish brown ; legs buff, 

 varied with brownish ; antennas dark brown, the scape reddish brown, 

 third and fourth joints white except at their tips. Length 8 lines.

Sesiosa stjbfasciata, Pascoe, I. c. p. 154, pi. 8. f. 2. 



The Wallacean specimen is from Singapore. The genus is allied 

 to Apomecyna. 



Praonetha. 



Prioneta (ab errore), Blanchard, Voy. au Pole Sud, iv. p. 292. 



Praonetha obducta, Pascoe, Long. Malay, p. 1G5. 



The puncturation is a little coarser than on the typical specimens 

 from Ceram and Bouru, on which I have based my description. 



Praonetha illicita, Pascoe, I. c. p. 169. 



It is possible that this is only a subspecies or variety of a widely 

 distributed species, and it will then be found to extend from Penang 

 to Java on the one hand, and to Aru on the other. Other localities 

 are Goram, Batchian, and Mysol. 



Praonetha consularis. 



P. fusca, pube densa Jtavida vestita; vertice maculis duabvs,
