anterior coxae. Mesosternal receptacle feebly raised, strongly 

 transverse, emargination widely transverse; cavernous. Legs 

 rather short; femora edentate, distinctly grooved. Other char- 

 acters as in Ferissops. 



The eyes are more coarsely faceted than in any of the close 

 allies of Perisso2ys, the prothorax is more transverse and the 

 femora are edentate, so that the genus is a rather distinct one. 



Elytra with a circular patch of dark scales posteriorly posticalis. 



Elytra without dark scales posteriorly munchis. 



Queens LANDiCA posticalis, n.sp. 



Reddish-brown, antennae paler. Elytra with large, soft, dingy 

 whitish scales, a large and almost circular patch of chocolate- 

 brown scales on posterior declivity. Under surface with large, 

 soft, round, dingy white scales; legs densely squamose. Head and 

 base of rostrum with dingy scales. 



Head with dense concealed punctures. Rostrum the length of 

 prothorax and rather wide, sides feebly decreasing in width to 

 antennae, thence parallel to apex; basal third strongly punctate, 

 elsewhere shining and finely but distinctly punctate. Scape 

 inserted two-fifths from apex of rostrum and the length of funicle; 

 two basal joints of the latter moderately long and subequal, the 

 others transverse. Prothorax bisinuate at base; with dense, round, 

 not very large punctures becoming minute at apex. Elytra 

 scarcely wider than prothorax and twice and one-half as long; 

 with series of moderately large almost entirely concealed punc- 

 tures; interstices regular and feebly separately convex. Undtr 

 surface with moderately dense punctures, each of which is trace- 

 able although covered by a scale. Posterior fetnora terminated 

 considerably before apex of abdomen; tibiae compressed and 

 lightly curved. Length 5|-, rostrum IJ; width 2J mm. 



Hah. — Lizard Island (Mr. G. Masters). 



As this species is very distinct, I have described it, although 

 on the unique specimen under examination the prothoracic scales 

 are almost entirely abraded; they appear, however, to be much 

 the same as on the elytra.
