Prosoaltus, gen. nov. 
Head strongly and obliquely produced ; eyes prominently 
elevated and globose. Vertex narrowed to half the breadth 
of one of the eyes, not advanced as far as the eyes ; frontal 
costa narrowly compressed between the antennae, scarcely 
protuberant; ^paired ocelli placed between the lower third 
of the eyes; antennae moderately long, filiform, articles 
distinctly elongate, inserted below the eyes. Pronotum 
deplanate, truncate anteriorly, posteriorly acuminate and 
extended beyond the hind femoral apices; prozonal carinae 
subobsolete; lateral carinae of process extended on the 
shoulders; lateral lobes slightly sublaminate expanded, and 
obliquely truncate; superior sinus very shallow, arcuately 
excavate for the reception of the minute elytra; wings 
fully explicate. Anterior and middle legs elongate, narrow, 
margins entire ; hind femora bearing acute antegenicular 
and genicular spines ; posterior tibial margins compressed, 
armed with minute spines; first articles of the posterior 
tarsi equal in length to the third. 
Resembling Systolederus , Bob, but having crassate 
stature, the head more produced, eyes more elevated, the 
superior sinus of lateral lobes obsolete, and the body 
provided with minute elytra. The type is P. oculatus 
described herewith. 
P. oculatus , sp. nov. 
Body somewhat crassate, granulate; colour dark ferru- 
gineous, variegated with pale ochre markings on the pro¬ 
notum and legs, hind femora bearing two light flavous 
bands, underneath parts black. Vertex not at all produced, 
depressed, and half the width of one of the eyes, middle 
carinate, longitudinally fossulate on each side between the 
eyes, frontal carinulse roundly elevated and convergent 
forward; eyes globose and strongly elevated above the 
dorsum, occiput largely exposed and sloping backward ; 
frontal costa very little protuberant between the antennae, 
divided below the paired ocelli, narrowly sulcate. Pro¬ 
notum granulate, median carina conspicuous but dis¬ 
appearing forward near the front border ; posterior process 
extended backward beyond the hind femoral apices and 
rather stout; posterior angles of the lateral lobes laminate 
expanded and obliquely truncate; elytra minute, narrow 
and acute at the bases and narrowly rounded at the apices ; 
wings dark, extended beyond the pronotai apex. Hind 
femora fuscous, bearing an oblique yellow band near the
