Ph. zabroides 81., differs from all others by its compact, convex 

 form, the striole at base of second interstice of elytra long and 

 deep, etc. 



Phorticosomus crassus, n.sp. 



Robust, convex. Eyes not prominent; prothorax transverse, 

 finely punctate on each side of base, basal angles not marked, 

 base biimpressed; elytra truncate-oval, strongly striate, inter- 

 stices convex, third impunctate; anterior tibiae wide at apex, and 

 with a strong, internal spur; intermediate tibiae wide at apex, 

 and with outer angle produced into a prominent, triangular pro- 

 cess. Black, legs reddish-piceous. 



Head convex (2*7 mm. across eyes); eyes round, lightly convex, 

 not prominent; front shortly impressed on each side at ends of 

 clypeal suture, Prothorax convex, wide (3 x 4*2 mm.), wider 

 across base (3-7 mm.) than apex (3 mm.); sides very lightly 

 rounded; anterior angles widely obtuse, not prominent; posterior 

 angles widely rounded, not marked; lateral margins a little wider 

 and punctate near basal angles; lateral basal impressions deep, 

 short, narrow, punctate; median line faintly impressed. Elytra 

 short (7 X 4-75 mm.), convex, rounded at humeral angles; lateral 

 apical sinuosities obsolete; striae deep; interstices light, convex 

 on disc; lateral interstices less convex than inner ones, these 

 narrower and more convex on apical declivity; punctures of ninth 

 interstice widely interrupted in middle. Tntercoxal part of pro. 

 sternum setose Metasternum punctate on each side. Ventral 

 segments 3-5 setigero-punctate on each side; third segment punc- 

 tate between coxai; fourth and fifth with a row of punctures 

 along anterior margin. Anterior cox«; not punctate; interme- 

 diate coxae closely punctate; posterior trochanters reniform, 

 smooth (two or three punctures near base); posterior femoia 

 punctate along lower external margin. Anterior tibiae with two, 

 small but decided teeth on outer side, above the larger apical 

 tooth. Length, 11-4; breadth, 4*75 mm.
