566 NEW SPECIES OF AUSTRALIAN COLEOPTERA, xiii., 



(the remarkable sculptui-e may be sexual, but, as the type is a 

 female, this is unlikely); the prothorax is also very much shorter, 

 and without the conspicuous medio-basal impression bounded 

 posteriorly by oblique ridges, being even shorter than in P. 

 ivallacei. The semi-doubhng of the apical joint of the antennje 

 is so conspicuous, that that joint appears to be really two; and 

 these regularly decrease in length, with the others, from the 

 eighth. On the type, the elytra are not entirely red, as the 

 suture, for a short distance, is black; and there is a slight infus- 

 cation on the disc of each at about the basal fourth; the latero- 

 basal margins (concealed from above) are also black; the legs 

 (except for the claws and tibial spines) and anteiniai are entirely 

 black. 



PSEUDOLYCUS BIVITTICOLLIS, n.Sp. 



9. Black, opaque; elytra and two prothoracic vitttie of a bright 

 brick-red; antenna3 with most of the eighth and ninth joints, and 

 the bases of the tenth and eleventh, obscurely red. Densely 

 clothed with pubescence, similar in colour to the derm on which 

 it rests. 



Head strongly convex between eyes. Antennae with third to 

 seventh joints wide. Hat, and subtiiangularly dilated to near 

 apex, eighth to eleventh much narrower and cylindrical, eleventh 

 conspicuously semi-double. Prothorax widest near apex, where 

 the width is slightly more than the length, but base less than 

 the length; with a shallow, median line from apex to base, and 

 somewhat dilated posteriorly: a shallow depression on each side 

 in front. Elytra much wider than prothorax; each with four, 

 conspicuous, costal elevations on disc; surface finely granulate. 

 Length, 14 mm. 



//«6.— N.S.W.: Galston (D. Dumbrell). 



In general appearance (except for the prothoracic vittfe) much 

 like the var. rujipennis of P. hceinori'hoidalis, and with antennjv 

 of very similar shape (but not colour); but diifers in having the 

 depressed median line of the prothorax commencing almost at 

 the extreme apex, and gradually dilating to the base, so that 

 there is not a medio-basal tiiangle. The eighth joint of antennae
