614 Mr. J. S. Baly's Descriptions 



remotely punctured ; antennae shorter than half the length of the 

 body, subincrassate, outer joints slightly compressed and subper- 

 foliate, eyes notched. Thorax subquadrate, scarcely broader 

 than long ; sides constricted in the middle, above subcylindrical ; 

 punctured as is C. impressa, the single longitudinal row of punc- 

 tures down the middle of the disc being also present as in that 

 species. Elytra oblong, much broader than the thorax, slightly 

 dilated behind, their apex broadly rounded ; above convex, indis- 

 tinctly flattened along the back, transverse depression below the 

 basilar space usually obsolete, at other times present, although 

 indistinct ; punctures arranged in eleven longitudinal rows, the 

 first of which is very short, the punctures are large, deeply im- 

 pressed, and placed at irregular intervals on the anterior half of 

 the rows, on the hinder half they become much smaller and indis- 

 tinct, the rows themselves being frequently entirely obsolete ; the 

 inner row next the suture is however always sulcate on the hinder 

 portion of its course, and, together with one or two of the outer 

 striae, remains always entire ; interspaces smooth, impunctate. 

 The amount of fulvous colour on the surface varies greatly ; in 

 some specimens, the black ground occupies almost entirely the 

 posterior three-fourths of the surface, the basal fourth, and a nar- 

 row line extending round the outer limb, alone being fulvous ; in 

 others the fulvous colour is extended inwards so greatly in all 

 directions (more especially however at the base and apex) as to 

 leave only a common central black patch. Under surface as in 

 C, impressa. 



4. Crioceris Pfeifferi. 



Oblongo-elongata, subcylindrica, sanguinea, nitida ; antennis 

 (basi excepta) elytrorumque dimidio antico, tibiis tarsisque 

 nigro-piceis ; elytris punctato-striatis, punctis infra basin sat 

 profunde, prope apicem tenuiter impressis.

Hab. Amboyna. First brought home by Madame PfeifFer, and 

 since then by Mr. Wallace. 



Head deeply constricted behind the eyes ; face forming a some- 

 what elongated triangle ; front smooth, without longitudinal im- 

 pression ; antennae scarcely half the length of the body, somewhat 

 slender, filiform, fifth joint shorter than the two preceding united, 

 basal three joints rufous, the rest black ; eyes broadly notched. 

 Thorax subquadrate, subcylindrical, sides deeply constricted in the 

 middle, surface smooth, nearly impunctate, a few remote punc-
