Hah. — Queensland : Cunnamulla, attracted to lights(H. Hard- 

 castle) — New South Wales : Tamworth(A. M. Lea), 



Close to the description of C. fcirvus, but base of prothorax 

 decidedly narrower than near apex. Very close to C. vernalis, 

 but smaller, eighth joint slightly longer and thinner, and spines on 

 undersurface of head much less distinct. The absence of an ab- 

 dominal fovea in the male distinguishes it from C. rivularis. 

 Ctenisophus longicornis, n.sp. (Plate xxi., fig.5). 



(J. Of a rather dark reddisli-castaneous, appendages somewhat 

 paler, abdomen darker, except at tip. Clothing much as in the 

 preceding species. 



Head with two round and rather shallow fovese between eyes. 

 Antennse decidedly longer than usual; first joint stouter than 

 second and slightly longer(but from some directions apparently 

 ■shorter), second stouter and slightly longer than third, thii-d to 

 seventh small and subequal; eighth to eleventh about two-thirds 

 the total length of antennae; eighth cylindrical, almost the length 

 of ninth and tentli combined, ninth and tenth subequal, eleventh 

 -elongate-subelliptic, distinctly longer than ninth and tenth com- 

 bined. Three apical joints of palpi each with a long thin append- 

 age. Prothorax moderately transverse, sides widest at apical 

 third, thence distinctly decreasing in width to base, which is not 

 much wider than apex; with a fairly large but rather shallow sub- 

 basal fovea. Elytra each with a strong sutural stria, and a 

 lightly curved discal one not quite so strongly impressed; with 

 numerous distinct punctures. Metasternum deeply sulcate. Ah- 

 ■domen with third segment large, its under surface feebly flattened 

 (not at all impressed) in middle. Legs long and thin. Length 

 l|mm. 



Q. Difi'ers in having shorter antennie, with the third to ninth 

 joints short and subaqnal, the tenth stouter and longer than 

 ninth(but much shorter than in male) and the eleventh shorter 

 and stouter than in tlie male, and as long as the four preceding 

 fiombined.
