under surface piceous; tarsi, palpi, and six apical joints of 

 antennae reddish, four basal joints of antennse piceous. 



Head large (2-5 mm. across eyes), strongly obliquely and everdy 

 narrowed behind eyes, subconvex between eyes, widely and feebly 

 impressed on each side between antennse; eyes large, hemi- 

 spherical, not inclosed at base, very close to buccal fissure beneath; 

 clypeus truncate; labrum long, almost covering mandibles, 

 roundly truncate and 6-setose at apex (the lateral setse long). 

 Mentum with a short, widely obtuse prominence in middle of 

 sinus. Labial palpi with apical joint elongate; penultimate 

 hardly shorter, bisetose in front. Antennse slender; basal condjde 

 exposed. Prothorax broader than long (1-8 [2'2 at sides] x 2-85 

 mm.), widest and subangulate just before middle; sides narrowed 

 to apex in an oblique curve, more lightly and subsinuately 

 narrowed to base; apex deeply and roundly emarginate; anterior 

 angles prominent, obtuse; base truncate; basal angles wide; disc 

 canaliculate, transversely striolate; margins explanate, widely 

 retlexed, widest at basal angles; a wide round depression near 

 each basal angle, these depressions connected by a rather wide 

 transverse impression; a setigerous puncture on edge of explanate 

 border at basal angle, and another at widest part of prothorax on 

 each side; a few fine setse on margin near each anterior an^le. 

 Elytra lightly convex, shortly ovate {Q 5 x 4-8 mm.), about twice as 

 wide at base as the base of the prothorax; humeral angles wideh^- 

 rounded; apical truncature of each elytron obliquely arcuate, a 

 short acute spine at outer angle; a long acute spine at apex of 

 second interstice; striae finely punctate; interstices convex or 

 subcostate, with a row of minute punctures down middle, third 

 with two distinct setigerous punctures about apical third, ninth 

 seriate-punctate, narrow and catenulate near shoulders; border 

 narrowly reflexed on sides, reaching peduncle; inflexed maroin 

 wide near base. Prosternum with intercoxal part narrow, 

 bordered on each side; mesosternum narrow between coxjb; meta- 

 sternum meeting mesosternum between middle cox^b in a sharp 

 point. Tarsi long, slender; three basal joints of anterior in male 

 slightly inflated; ungues finely pectinate near base. Length 11, 

 breadth 4*8 mm.
