264 MR. c. o. WATERHOUSE ON [Feb. 15, 



Stenispa, but differ from them and from the species of CephaloUa 

 in having a small acute frontal tubercle, and in having a raised inner 

 margin to the eyes. 



17. HoMALispA CRiBRiPENNis, n. sp. (Plate XXX. fig. 1.) 



H. nigra; capite thoraceque Jlavis, elytris cyaneis,fortiter crebre 

 punetatis. 



Long. 3 lin. 



Head obscure yellow, dusky about the eyes. Thorax at the base 

 about two fifths broader than long, very obliquely narrowed an- 

 teriorly, impunctate, shining, convex on the disk, impressed at the 

 sides ; the anterior angles acute, but very slightly prominent ; the 

 sides very slightly arcuate, nearly straight ; the posterior angles 

 very acute ; the base widely sinuate on each side. Scutellum black, 

 smooth. Elytra deep blue, shining, moderately convex, a little 

 broader than the thorax, subparallel, obtusely rounded at the apex ; 

 very strongly and closely punctured, the punctures near the sutures 

 forming lines; the apical margins are very finely crenulate. Abdo- 

 men fulvous. The base of the anterior femora is yellow. 



A second specimen has the abdomen and the anterior legs entirely 

 black. The specimens are probably sexes. 



This species may be placed near H. javeti, Baly ; but the confused 

 punctuation of the elytra separates it from all the species known to me. 



18. HoMALisPA coLLARis, u. sp. (Plate XXX. fig. 2.) 



H. nigra, nitida ; thorace pallide flavo, elytris striato-punctatis, 

 vix cyaneo-tinctis. 



Long 3^ lin. 



Thorax about two fifths broader than long, slightly narrowed in 

 front, gently convex on the disk, a little impressed within the pos- 

 terior angles, shining and impunctate, pale yellow, with the anterior 

 margin black in the middle ; the base in the middle and the fine 

 iucrassated basal margin are also black ; the anterior angles are very 

 little prominent and are moderately obtuse ; the sides are gently 

 arcuate in front of the middle, straight (or only extremely gently 

 sinuate) behind ; the posterior angles slightly diverging and very 

 acute. Scutellum smooth. Elytra distinctly broader than the 

 thorax, elongate-oblong, moderately convex, a little narrowed at the 

 base, parallel at the sides, obtusely rounded at the apex ; black, with 

 an obscure tint of dark blue, with lines of rather fine but distinct 

 punctures, the interstices smooth ; the punctuation obscure and 

 irregular at the apex ; the margins are impressed below the shoulders 

 and a little reflexed ; the apical margins finely crenulate. Under- 

 side of the prothorax and the base of the anterior femora yellow.

The specimens brought by Mr. Buckley differ from that described 

 by Mr. Baly from Ega in having no black spot on the shoulder of 

 the elytra.
