of the joints from the third to the tenth is gradually widened from the base to within 

 a short distance of the apex, being a little more prominent in front with the apical 

 angle rounded off ; the upper face of each of these joints is sparsely punctate, the 

 lower furnished with an elongated fossa, which is very densely and minutely punctulate. 

 The prothorax has on each side a strong submedian tooth, behind which it is obliquely 

 and sinuately cut away towards the basal margin, the latter being much narrower 

 than in other species of the genus ; the proiiotum is smooth and almost impunctate 

 except in two depressed spaces near each side— one broader close to the lateral margin 

 in front of the submedian tooth, the other narrower close to the oblique lateral margin 

 behind the tooth." 



I am now able to supplement the above description by stating the differences that 

 characterise the female : — xlntennse less than half the length of the body, not extending 

 beyond the basal fourth of the elytra. Mandibles shorter and stouter than in the 

 male and less strongly curved, the space circumscribed by them when closed being sub- 

 circular, and not transversely oval. Pronotum with its sides converging slightly from 

 the submedian tooth to the apex, the surface punctate, the punctures large, but not 

 close except on the anterior part. The sides of the pronotum behind the submedian 

 tooth are not depressed nor densely punctate as in the male, but are merely marked 

 with a few large sparse punctures.

Clytus (Perissds) wollastoni, sp. n. (Plate VI. fig. 7.) 



Head densely covered with luteous-white pubescence, prothorax similarly covered 

 with luteous-white pubescence except along the middle, which is marked with a 

 blackish-brown velvety band ; this band is ovately dilated behind the middle, gradually 

 narrowed in front and abruptly constricted near the base. Elytra dark brown, with a 

 broad submarginal luteous-white band extending from base to apex, and a subsutural 

 luteous-grey band which widens out towards the base and is also widened in the 

 posterior third of its length. Body beneath grey. Legs dark brown. Antenna;
