528 Mr. Friincls P. Pascoe's Notes on 



prothorax irregular, tuberous on each side the disc, with a smooth 

 elevated black line in the centre, which shortly bifurcates poste- 

 riori}'^ ; scutellum transverse, rounded behind ; elytra strongly 

 punctured, two obscure costae on each, the inner near the base 

 with a small tuft of hair ; beyond this the costae, including two 

 given off from the shoulder, are nearly obsolete, until at the de- 

 clivity towards the apex the inner two become prominent ; body 

 beneath and legs greyish-fulvous, speckled with brown ; antennae 

 fulvous, slender, slightly ciliated beneath. 



Length C lines. 



The pile on this insect under a lens seems of a golden hue, but 

 seen in conjunction with the dull brown derm beneath it, the tone 

 is very much sobered down. It is a very distinct species. 



3. Hehecerus covfertus. 



H. niger, pube griseo-cinerea, nigro-setosus; prothoracis disco 

 bicalloso ; elytris irregularibus, plaga magna nigra albo-lim- 

 bata pone medium ; antennarum articulis septem ultimis 

 duobus prascedentibus brevioribus, 



Sydney. 



Black, covered with a fine greyish-ashy pile, and with slender 

 black setose hairs ; head without an impressed line in front ; an- 

 tenuce brownish, the last seven joints together shorter than the 

 preceding two ; prothorax remotely punctured, a small but very 

 distinct callosity on each side of the disc, behind and between 

 these the prothorax is minutely corrugated : scutellum rounded 

 behind, covered with a dense whitish tomentum ; elytra coarsely 

 punctured, somewhat hollowed out inside the shoulder and round 

 the scutellar region, and again hollowed out in a longitudinal form 

 posteriorly midway between the side and the suture, the edges of 

 the hollow forming a kind of costa on each side, the outer of 

 which is continued back to the shoulder ; behind the middle a 

 large, nearly transverse black patch, indistinctly bordered with 

 white ; body beneath and legs with a rough, greyish pile. 



Length 4 lines. 



Also very distinct : tlie surface of the elytra more irregular than 

 in any other species ; and the terminal joints of the antennae more 

 crowded than usual. It serves to show, once more, how uncertain 

 are technical characters, and that in the descriptions of genera it 

 is necessary to take into consideration details which it is scarcely 

 possible to record, that in Hehecerus plumula the third antennal 

 joint is scarcely longer than, or at most about half as long again 

 as, the second, while it is about ten times longer in the species
