POROPTERUS PARVIDENS, n. Sp. 



(S . Black ; antennas tibial hooks and claws more or 

 less red. Rather sparsely clothed with large ashen-grey scales, 

 usually becoming much darker on tubercles ; under-surf ace 

 and legs with ashen scales irregularly mixed with sooty ones, 

 the legs with stout sooty setae as well ; apical half of head 

 and rostrum to antennae rather densely clothed. 



Head with minute punctures, and very finely shagreened ; 

 ocular fovea rather large but partly concealed. Rostrum 

 moderately long, sides very feebly incurved to middle, 

 •obsoletely carinated along middle to antennae, apical third 

 with fairly dense but rather shallow punctures. Antennae 

 inserted about two-fifths from apex of rostrum; scape rather 

 short; first joint of funicle stouter, but slightly shorter than 

 second. Prothorar slightly longer than wide; with two large 

 median tubercles; subapical constriction interrupted in 

 middle, deep and irregular on sides ; elsewhere deeply and 

 irregularly grooved. Scutelhim small. Elytra suddenly, but 

 not much, wider than prothorax, subparallel-sided to near 

 apex; with large distant punctures, larger on sides than 

 •elsewhere; with four large tubercles — two at basal fourth and 

 "two crowning the posterior declivity; between these four 

 smaller tubercles placed transversely, the inner ones much 

 larger than the outer ones, but considerably smaller than 

 "the four large ones; shoulders tuberculiform. Mesosternal 

 receptacle rather large and elevated at base, emargination 

 with thin widely-U-shaped walls, sloping down to front coxae. 

 .4 hdom en with basal segment as long as three following com- 

 bined, these with straight sutures, those of the third and 

 fourth deep. Legs long and thin: femora subclavate, very 

 feebly dentate, posterior passing elytra ; third tarsal joint 

 rather wide and deeply bilobed. Length, 8J-9 mm. 



9 . Differs in having somewhat shorter legs (but the 

 liind femora pass the elytra), rostrum longer, thinner, clothed 

 only near base and with smaller but more clearly-defined 

 punctures, and antennae inserted not quite so close to apex 

 of rostrum.

 (H. W. Cox and A. M. Lea). Type, I. 1297, in South Aus- 

 tralian Museum. 



In some respects an aberrant species and approaching 

 niidgea, but head not as in that genus, eyes larger and with 

 •smaller facets, abdomen with second segment distinctly longer 

 than third, etc. It is a narrow, deep species, with large 

 tubercles, some of which are sometimes obscurely diluted with 

 red. The teeth of the four hind femora are so small that 

 they could be readily overlooked ; those of the others are
