the third stria, the third puncture about the apical fifth near the 

 second stria. The ungues are strongly pectinate. 



Sarothrocrepis mucronatus, n.sp. 



Head large (2 mm. across eyes); prothorax transverse, base 

 wide, lobate; elytra wide, strongly striate, third interstice bi- 

 punctate near course of third stria, each elytron with a short 

 spiniform process at outer and inner angle of apical truncature; 

 legs as in Sarothrocrejns; tarsi with penultimate joint deeply 

 emarginate, ungues strongly pectinate. Dark piceous; prothorax 

 with explanate margins testaceous; elytra with reflexed border 

 and marginal channel ferruginous; under surface of prothorax, 

 mesothorax, metathorax, inflexed margins of elytra and femora 

 pale testaceous; abdomen piceous, lighter-coloured near posterior 

 COX80; tarsi, antennae, and palpi ferruginous. 



Head convex between eyes, not narrowed behind eyes; upper 

 surface distinctly punctate; front and clypeus rather rugulose; 

 eyes very large and prominent. Antennae slender, inserted close 

 to eyes, three basal joints glabrous. Prothorax transverse 

 (1'85 X 2*8 mm.); apex truncate, same width as neck; sides 

 roundly ampliate from apex without marked anterior angles, 

 attaining greatest width and rounded about middle, very little 

 (roundly) narrowed to base ; basal angles strongly marked, 

 rectangular but not acute, bearing a setigerous puncture; disc 

 convex; lateral margins explanate, very wide at base, becoming 

 narrow near apex; base truncate on each side of peduncle (behind 

 testaceous explanate margin), middle rather strongly produced 

 backwards and forming a well marked wide lobe; sinuosity on 

 each side of basal lobe wide but decidedly marked. Elytra wide 

 (6-5 X 4-5 mm.), widest behind middle, convex; base widely 

 rounded on each side of peduncle; striae strongly impressed, 

 finely crenulate at bottom, seventh ending near suture in an 

 ocellate setigerous puncture opposite apical extremity of third 

 interstice; interstices convex, four inner ones not convex — 

 except towards base, first narrow, ending at apex in a short 

 mucro, becoming wider and bearing an elongate strongly im-
