is evenly distributed and not at all inclined to linear arrange- 

 ment, although the elj'-tra present some obscure indications of 

 longitudinal striation ; the transverse wrinkles on the same are 

 very noticeable. The tibiae are very like those o£ Hypoplilcsus, 

 but the anterior pair are a little more dilated towards the apex, 

 with the margins a little more sinnated, and the inner apex of 

 all the tibicT is briefly spined as in Alphitohius. 



A few sj^eciineus have occurred to me under bark of 

 JEucalt/2)tus, near Port Lincoln. 



TOxicrM. 

 T. curvicorne, sp. nov. Nigrum opacum ; cornibus capitis sat 

 elongatis ; prothoracis apice leviter lobato ; antennarum 

 clava quadri-articulata. Long. 5 1. 



The thorax is about one-fifth wider at the base than long ; it 

 is distinctly though not strongly lobed in front ; the sides are 

 nearly straight, and are parallel to each other ; the posterior 

 angles are sharply rectangular, the anterior roundly obtuse 

 and little prominent ; just within the posterior angles on either 

 side is a rather short and ill-defined longitudinal fovea ; the 

 surface is feebly and sparingly, but distinctly, punctured. The 

 elytra are striated, the stride becoming better defined as they 

 recede from the base and the suture. Each stria is set with 

 moderately large and strong punctures, about 50 punctures in 

 each of the striae near the suture, a smaller number in the 

 external ones. In the male the entire upper surface of the 

 head is flattened, or rather very slightly concave, and is 

 punctured somewhat similarly to the thorax, except that the 

 punctures are quite sparse in front and become gradually 

 closer backwards. The anterior pair of horns are about as 

 long as the apical joint of the maxillary palpi and are inclined 

 outward and forward. The length of the posterior horns is 

 about the same as the length of the head. They are strongly 

 compressed, their wide faces turned towards each other. They 

 are strongly arcuate (their cojivexity on the outside) and 

 nearly meet at their apices, which are clothed with yellow hair. 

 In the female the upper surface of the head is flattened, some- 

 what uneven, and rather closely punctured, with two slight 

 ridges where the posterior horns take their rise in the male. 



I have a single pair of this insect, which were sent to me 

 from Victoria.
