ridges appear distinctly as such, rather than as supports for 

 fascicles, and the punctures and grooves are much more con- 

 spicuous, although really not larger. The prothoracic carina 

 is not transversely impressed at the apical third, and the 

 minute dermal scales are also greyish, so that the derm be- 

 tween the larger scales does not appear to be everywhere 

 jet-black. 



POROPTERUS BASIPENNIS, n. Sp. 



Densely clothed with small ashen - grey (almost 

 stramineous) scales, closely applied to derm; with numerous 

 stout, but similarly coloured, scales, scattered about and be- 

 coming fascicles on tubercles, but the fascicles usually with 

 a dark centre; legs, head, and rostrum (almost to tip) densely 

 squamose. 



Head somewhat depressed, punctures normally concealed. 

 Rostrum rather long, parallel-sided from base to antennae, 

 and then slightly dilated to apex ; punctures normally con- 

 cealed except at apex. Antennse inserted one-third from apex 

 of rostrum; second joint of funicle almost twice the length 

 of first. Prothorax longer than wide, sides rounded in middle, 

 apex produced and bif asciculate ; with two feeble median 

 tubercles supporting distinct fascicles; subapical constriction 

 deep on sides, but shallow across middle; sides near base, 

 deeply grooved. ScvteUum absent. Elytra long, narrow, 

 and deep; sides widest just beyond the middle, and strongly 

 arcuate near apex ; with rows of large round punctures, 

 larger and more distinct on the sides than elsewhere ; shoulders 

 produced; third interstice conspicuously produced at base, 

 fasciculate at basal fourth, and about the middle; fifth inter- 

 stice with a feeble fascicle about the middle, and another 

 posteriorly ; suture conspicuously fasciculate halfway down 

 the posterior declivity, and apex bif asciculate. Mesosternal 

 receptacle raised, basal portion large, emargination semi- 

 circular. Abdomen with numerous punctures; basal segment 

 as long as three following combined, intercoxal process con- 

 spicuously triangular, suture incurved to middle of apex, 

 second decidedly longer than third and fourth combined, and 

 much longer than fifth. Legs long and thin; hind femora 

 not extending to apex of abdomen ; third tarsal joint 

 moderately wide and deeply bilobed. Length, 11 mm. 



Hah. — Queensland: Mount Bellenden-Ker (A. Solari 

 from — Podenzana). 



A narrow species with peculiar clothing and otherwise 

 very distinct from all previously described species. The 

 fascicle on the suture is at the same position as on stenogaster, 

 but the two species have little else in common. The clothing 

 is so dense that no prothoracic punctures are visible, nor is a
