304 Mr. A. Murray's Monograph of the genus Catops. 



angles are obtuse, except at the very angle, where there is an 

 exceedingly minute rectangular starting-point. The surface is 

 qparsely granular. The scutellum is small. The elytra are gra- 

 nulated and have a distinct sutural stria, but apparently no 

 others — at least the traces, if any, are exceedingly indistinct. 

 The anterior tarsi and first joint of the middle tarsi are dilated 

 in the male. 



This species has some resemblance to C. chrijsomeloides, but it 

 is smaller, the thorax is narrower and more transverse, the an- 

 tennse are not so heavily clubbed, and the joints are differently 

 proportioned. It has also some resemblance to C. tristis, but 

 the form of the thorax as well as a difference in the pubescence 

 distinguish it. The pubescence is coarser and more dense than 

 in most other species. 



From the East Indies (Boys' collection). The above descrip- 

 tion is taken from a unique (male) example kindly presented to 

 me by my friend Mr. Westwood.

 " Oblongo-ovatus, fusco-piceus, tenue-pubescens; anten- i 



nis mediocribus, clavatis,basi ferrugineis; thorace brevi 

 transverso, basi parum latiore, angulis posticis obtusis ;

 "Long, lilin., lat. I lin.* '' 



Body black, covered with decumbent pale hairs. Head 

 minutely punctured; antennae shorter than the prothorax, the 

 two first joints ferruginous, the eighth shorter and smaller than 

 the rest ; mouth and palpi ferruginous ; prothorax not visibly 

 punctured, with all the angles rounded ; base with a slight sinus 

 on each side ; elytra acute, very minutely punctured, with a hair 

 emerging from each puncture, without furrows, except a single 

 one parallel with the suture, ferruginous, black at the tip ; ab- 

 domen piceous, rufous at the base ; legs ferruginous. 



Found in the Sitka Islands by Eschscholtz and Kuprianoff. 



A comparison of the authentic unique specimen of Kirby's 

 Choleva Spenciana preserved in the British Museum, with speci- 

 mens of Mannerheim's Catops cadaverinus, shows that they are 

 the same species.
