sculpture. The elytral granules in P. assimilis are rather 

 coarser, in single series (except on the third interstice), and with 

 only the alternate interstices represented (by two or three 

 granules each) on the declivity; the humeral angles are also more 

 prominent. 



PSALIDURA PERLATA, n.Sp. 



^. Of a short, ampliate form, convex. Prothorax finely granu- 

 late; elytra striate, interstices granulate, apical excavation 

 shallow, no fascicles present; forceps hidden, apices not meeting. 

 Black, legs reddish; densely clothed with grey and yellow scales, 

 giving elytra a maculate appearance; apical tergite clothed with 

 yellow hair; legs with yellow setae and short white scales inter- 

 mingled; setae yellow. 



Head wide, convex, rather sparingly setigero-punctate. Ros- 

 trum well marked off from head, external ridges wide, feebly 

 convex, internal ridges depressed, lateral sulci and median basal 

 notch represented by three small isolated impressions along trans- 

 verse sulcus; median area narrow, depressed in front behind 

 marginal plate. Mandibles simple, the outer portion thickly 

 covered with stout yellow setse. Mentum sparsely bearded, 

 dentate anteriorly. Prothorax(6 x 7 mm.) roundly dilated, widest 

 in front of middle, apical lobe feebly produced, no collar- constric- 

 tion nor median line. Closely covered with round, black, shining 

 discrete granules, closer together and finer in the centre. Elytra 

 (13x8 mm.) evenly rounded on sides, very wide; apex strongly 

 flanged, not mucronate; base feeble excavate, humeral angles 

 marked but not prominent; disc with rather shallow longitudinal 

 striae, the sculpture of which is obscured by the thick clothing 

 but not foveate; interstices rather broad, irregularly granulate 

 in double series, the granules unequal in size, the larger ones 

 slightly flattened, shining, each bearing a long decumbent yellow 

 seta. Sides somewhat irregularly granulate, rather more coarsely 

 than on disc. Metasternum transversely concave, the lateral 

 margins raised on each side in the form of a prominent tubercle 

 beyond the level of the middle coxae. Third and fourth ventral
