 BY JOSEPH S. BALT, F.L.S. 



Sub-Fam. HALTICIN^. 



ACBOCETPTA PALLIDA. 



JRotundata, postice vice attenuata, valde convexa,Jlavo-fulva, nitida, 

 teniiiter punctata, punctis in elytris irrequlariter suhstriatim dispositis ; 

 oculis antennisque extrorsum nigris. Long. 2| lilies. 



Hab. : Sumatra ; collected by Mr. Wallace. 



Head very short, transverse, vertex finely punctured ; encarpse distinct, quadran- 

 gular, nearly contiguous at the apex ; eyes elongate, their inner border slightly 

 sinuate ; antennae rather longer than the thorax, slightly thickened towards the 

 apex, four outer johits pitchy-black. Thorax nearly three times as broad as long, 

 obliquely bisinuate on either side at the base, medial lobe moderately produced, 

 broadly rounded ; sides obliquely converging from the base towards the apex, all the 

 angles broadly rounded. Scutellum elongate-trigonate. Elytra rather broader at the 

 base than the thorax, shoulders distinct, but abruptly rounded, inflexed limb broadly 

 dilated ; surface more distinctly punctured than the thorax. Legs short, robust. 



ACKOCEYPTA PUEPUREA. 



Rotundata, convexa, metallico-putpurea, capite corporeque suhtus 

 piceo tincfis, antennis incrassatis, nigris {articulus ultimus caret); thorace 

 sub-remote punctato ; elytris fortiter punctatis. Long. 2\, lin. 



Hab.: Borneo (Sarawak). 



Head similarly sculptui-ed to A. coccinelloides ; antennae more robust than in 

 that species, the second and third joints slender, ten lower joints black;* base of 

 jaws and anterior border of labrimi rufo-fulvous. Thorax three times as broad as 

 long; basal margin rounded, slightly oblique and faintly bisinuate on either side; 

 sides obliquely converging and slightly rounded from base to apex, hinder angles 

 obtuse, the anterior produced, thickened, very obtuse ; disc sub-remotely punctured. 

 Scutellum broad, trigonate. Elytra broader than the thorax, shoulders obsolete, 

 surface rather coarsely punctured ; inflexed limb horizontal, sliglitly concave, its 

 outer edge scarcely produced. 



ACROCEYPTA COCCINELLOIDES. 



Rotundata, convexa, piceo-nigra, nitida, ahdoonine ftisco-fulvo, piceo 

 tinctOjfemorihus anticis dorso, tihiisque anticis quatuor intus, piceis ; 

 antennis modice incrassatis, nigris, articulo ultimo albido, thorace 

 nigro, tenuiter punctato, laterihus anguste piceis; scutello elytrisque 

 rufis, his distincte punctatis, singulatim maculis nigris, 5, 2, 2, 1 dis- 

 positis, ornatis. Long. 2\ lin. 



Hab. : Borneo (Sarawak). 



• I possess three specimens of this species, but in rach th« antennae are imperfect. — J. S. B.
