XXXV.—Descriptions of a new Genus and of new Species of 
Halticine. By Josep S. Baty, F.L.S. 
Genus Hypuasis, v. Harold, 
Deutsch, ent. Zeit., Dec. 1877, p/ 433. 
Corpus rotundato-ovatum, modice convexum. Caput in thoracem 
insertum, facie perpendiculari; encarpis distinctis, contiguis : 
carina lineariformi, elevata; antennis filiformibus. Thorax 
transversus, lateribus reflexo-marginatis. Scutellum trigonatum. 
Elytra thorace latiora, reflexo-marginata, modice convexa, con- 
fuse punctata ; limbo inflexo concayo, margine externo deorsum 
producto. Pedes mediocres, femoribus posticis valde incrassatis ; 
tibiis dorso canaliculatis, posticis extus ante apicem emarginatis, 
apice spina acuta armatis; t2bizs anticis quatuor apice inermibus; 
tarsis posticis articulo basali duobus sequentibus conjunctis lon- 
gitudine zequali vellongiore; unguidus posticis inflatis; wnguiculis 
appendiculatis. Prosternwm oblongum aut anguste oblongum, 
apice obtusum aut truncatum, disco plano aut longitudinaliter 
concavo ; acetabulis anticis apertis. Mesosternum obliquum aut 
subhorizontale, apice emarginatum. 
The short, plane or longitudinally concave prosternum, the 
concave ipflexed limb of the elytron, together with the general 
form of the body, will, combined, separate this genus from 
Homophoeta; the form of the prosternum, together with the 
difference in the length of the basal metatarsal joint, will sepa- 
rate it from Gdionychis. 
Hyphasis coccinelloides. 
H., rotundato-ovata, modice convexa, pallide flava, nitida, antennis 
(basi excepta) fuscis ; oculis nigris ; thorace levi, obsolete punctu- 
lato; elytris subcrebre punctatis, utrinque maculis subrotundatis 
quinque nigris ornatis, harum prima communi circa scutellum, 
secunda vix infra basin supra callum humerale, rotundato-ovata, 
duabus prope medium transversim positis, quintaque ante api- 
cem, prope limbum externum sita. 
Long. 22 lin. 
Hab. Borneo, Sarawak. Collected by Mr. Wallace. 
Vertex shining, impunctate ; encarpe transversely quadrate ; 
carina elongate, its upper end thickened; antenne with the 
four lower joints flavous, stained with piceous, the rest fus- 
cous. Thorax more than three times as broad as long; 
sides broadly margined, strongly reflexed, rounded and con- 
verging from base to apex, parallel at the extreme base, the 
anterior angles thickened, armed with a small excurved, acute 
tooth ; surface nitidous, faintly impressed here and there with 
fine punctures ; lateral margin longitudinally excavated. Apex
