median carina traceable. On the type, which is almost cer- 

 tainly a male, two of the prothoracic, and five of the elytral, 

 fascicles are conspicuously dark in the middle. In favourable 

 lights the derm appears to be covered with similar minute 

 black scales to those of the preceding species. 



POROPTEEUS PLATYDERES, n. Sp. 



(j" . Densely, but in places sparsely, clothed with stout 

 ochreous or light-brown scales, usually closely applied to derm, 

 becoming fasciculate, and usually darker on tubercles; legs, 

 head, and rostrum to antennae densely clothed. 



Head somewhat depressed. Rostrum rather short and 

 stout, very feebly curved, parallel-sided to between antennae, 

 and slightly dilated in front of same; with numerous small 

 but clearly-defined punctures in front, elsewhere larger but 

 more or less concealed. Antennae rather thin, inserted one- 

 fourth from apex of rostrum ; second joint of funicle twice 

 the length of first. Prothorax wide and almost flat, basal 

 half almost parallel-sided, thence strongly narrowed to apex, 

 which is conspicuously produced and bifasciculate ; median 

 carina absent; subapical constriction feeble. Scutellum absent. 

 Elytra wide, closely applied to prothorax ; with rows of large 

 punctures, more regular but not larger on sides than along 

 middle ; base with six tubercles, of which the largest are 

 humeral, third interstice with three fairly large tubercles, one 

 just before and one just after middle, the other just below 

 summit of posterior declivity, fourth interstice with a sub- 

 basal tubercle, at first appearing to be on the third, seventh 

 interstice almost ridged from beyond the middle to near apex ; 

 apex obtusely bituberculate, several feeble tubercles elsewhere ; 

 about suture with some shining granules. Mesosiernal recej)- 

 facle large, emargination strongly transverse. Abdomen with 

 numerous more or less concealed punctures ; basal segment as 

 long as three following combined ; a deep curved groove near 

 base ; second segment slightly shorter than fifth, and distinctly 

 shorter than third and fourth combined ; sutures deep and 

 straight. Legs moderately long ; femora rather stout, each 

 with a feeble subapical ridge, culminating in a small but dis- 

 tinct tooth, posterior almost extending to apex of elytra ; third 

 tarsal joint wide and deeply bilobed. Length, 9-11 mm. 



9 . Differs in having the rostrum longer, thinner, more 

 noticeably dilated to apex, clothed only about extreme base 

 and with smaller but more clearly-defined punctures : antennae 

 inserted not quite so close to apex of rostrum, and legs slightly 

 shorter.
