92 Mr. D. Sharp ow some 



doubt I am correct in considering them to be of the 

 male sex. 



Greymouth ; No. 227, Helms. 



Didymocautha robusta, n. s. 



Fuscula, capite thoraceque rufis, antennis pedibusque 

 rufo-testaceis ; elytris nitidis, fortiter punctatis, pube- 

 scentia sparsa erecta vestitis, ex parte majore testaceis, 

 argute-fusco signatis. Long. V2j mm. 



Head red, coarsely punctate and much pubescent. 

 Antennae pale red, their basal portion much pubescent ; 

 towards the apex the pubescence becomes gradually' less, 

 and is wanting on the apical joint. Thorax red, about 

 as long as broad, the surface very uneven, with a smooth 

 longitudinal space on the middle, on each side of which 

 are coarse punctures ; this smooth space does not 

 extend to the front part, which is coarsely punctate ; on 

 each side of the middle towards the front there is a very 

 distinct shining tubercle, and externall}'' to this a less 

 distinct sublateral tubercle ; the angle at the side behind 

 the middle is very prominent ; the surface bears much 

 pale pubescence. Elytra shining, definitely and coarsely 

 punctate, and from each puncture there rises a pallid 

 suberect hair ; the punctuation is distant and regular ; 

 along the side of the wing-case, from the shoulder to the 

 apex, extends a dark mark, and across the surface stretch 

 two transverse irregular fasciae of dark colour, the 

 anterior one is angulate, and, as it proceeds from the 

 side to the suture extends forwards, and along the 

 suture extends to the scutellum ; the posterior transverse 

 fascia is broad and angulate, and sends a narrow pro- 

 longation backwards along the suture to the apex. The 

 femora are red, and stout for this genus ; the tibiae and 

 tarsi yellow ; under surface fuscous-red, with very scanty 

 fine white pubescence. The individual before me is of 

 uncertain sex. 



The shorter and stouter femora distinguish this insect 

 strongly from 1). sithlineata ; probably it is allied to 

 D. picta, Bates, a species I liave not seen.
