niiddle, the sides rounded in front, sinuate towards the base and finely mar- 

 gined throughout; disc evenly convex, with two deep oblique foveae before 

 the base ; the median area has very coarse punctures, with a group of smaller 

 ones on each side in front of the fovea ; towards the sides and the basal angles 

 the punctures become very minute and sparse. Elytra ovate, the piceous area 

 finely, almost obsoletely, punctulate, the pale spots free from punctures. Legs 

 piceous, the tarsi paler. 



Length 2|-5 mm. 



Hah. New Guinea, Dorey {Wallace). 



Closely allied to P. luallacei, from which it differs in colour and in 

 the longer rostrum. 



Flatysalpingus approximatus, sp. n. 



Closely resembling P. hngirodris and P. alhonotatns, but with the basal 

 spots of the elytra situated closer to the suture. Rostrum intermediate in 

 length between that of P. long'u-ostris and P. alhonotatus, the sides of tlie 

 thorax very obscurely denticulate, again intermediate between the two species 

 named. Puncturation of the thorax very coarse, covering a triangular area 

 from the middle of the base to near the anterior angles, the punctures being 

 largest towards the apex of the triangle and decreasing forwards and laterally. 



Length 3 mm.

The British Museum possesses a single specimen from Amboyna 

 ( Wallace) that I I'efer to this species, the type of which was from the 

 Kei Islands. 



In colom* and markings it closely resembles P. longirostris (supra), 

 but differs in the shorter, stouter rostrum, which is onl}^ about double as 

 long as its width at the points of insertion of the antennae. The sides 

 of the thorax are bluntly denticulate, each with four teeth bearing a 

 single stiff hair ; the last of these is much more developed than the 

 others and forms the posterior angle of the thorax. In this respect 

 P. albonotatus forms a transition stage between Platylissodema and 

 JPlatysalpingus ivallacei, in which the lateral teeth, with the exception 

 of that forming the posterior angle of the thorax, are obsolete, though 

 represented by their setae.

Remarkable for its antennal structure. Besides the two Central 

 American species placed here by Champion, Pic has added L. hrasillensis
