Hob. — Queensland: Cairns district (A. M. Lea). T}^pe 

 (unique), I. 5726. 



A jet-black species, very close in general appearance to 

 howensis, but legs partly darker, antennae mucli more con- 

 spicuously serrated, and head with paler clothing. To see 

 the blackish pubescence clearly the insect must be viewed 

 from the sides. 



MlCRORHAGUS TENUICORNIS, n. sp. 



Black; base (including hind angles) of prothorax, 

 scutellum, basal third (or fourth) of etytra, and the suture 

 more or less conspicuously diluted with red, legs bright-red, 

 antennae piceous-brown, two basal joints, or second only, 

 somewhat paler. Moderately clothed with stramineous 

 pubescence about base of prothorax and of elytra, elsewhere 

 with black or ashen pubescence. 



Head with a fine transverse subbasal carina ; with very 

 dense punctures, clearly denned behind carina, partially con- 

 cealed in front of same. Antennae long and thin, very feebly 

 serrated ; second joint very short, third almost as long as fourth 

 and fifth combined, eleventh distinctly longer than tenth. 

 Prothorax strongly transverse, front angles rounded, sides 

 slightly dilated at posterior angles, these strongly produced 

 and acutely carinated, with a short medio-basal carina, con- 

 tinued as a depressed median line to apex, front margin with 

 a fine carina, which on each side has a short spur projecting 

 obliquely backwards; with crowded punctures of moderate 

 size. Elytra lightly but regularly decreasing in width 

 posteriorly ; with crowded and rather coarse asperate punc- 

 tures about base, becoming smaller posteriorly ; with a distinct 

 sutural stria beyond the middle on each elytron, elsewhere 

 with but feeble remnants of striation. Prosternal sulci deep, 

 narrow, and parallel-sided almost throughout; propleural 

 parallelograms about thrice as long as wide. Length, 

 2|-3f mm.

There are four specimens under examination and they 

 •differ but little, inter se, except in size. 



The species known to me may be tabulated as follows : — 



Antennae* flabellate ... ... ... ... ... cairnsensis 



Antennae not flabellate. 

 Prothorax bright-red ... *... ... ... rufi colli s 



Prothorax (base sometimes excepted) black or 

 blackish. 

 Third joint of antennae longer than fourth 



and fifth combined ... ... ... variegatus
