Lea — On Australian Coleoptera 389 



thorax at Ijasc about once and one half as wide as the median length, at apex 

 less than the median length, sides obliquely narrowed from base to apex; with 

 dense and sharply defined punctures of moderate size, becoming denser and 

 larger on sides. Elytra ( for the genus) rather long, sides obliquely decreasing to 

 apex ; with rows of moderately large punctures, at the sides and apex set in 

 rather deep striae ; interstices with sparse and small punctures. Front legs slightly 

 longer than the hind ones, basal joint of front tarsi somewhat produced on one 

 side. Length ( 6 ^ ), -'5-3 mm. 



9 Differs in being more robust, eyes slightly more distant, antennae thinner, 

 elytra less narrowed posteriorly, abdomen more convex and with a large apical 

 fovea, and front legs no longer than the hind ones, with the basal joint of tarsi 

 smaller and not lop-sided. 



Hab. Western Australia; Cue (H. W. Brown). Type, L 4421. 



.An elongate species, with longer prothorax than usual, but the five-jointed 

 club, incurved end of prosternal process, and minute scutellum indicate that it 

 should be referred to Ditropidus; the scutellar lobe is notched, but the notch is 

 very feeble. The elytral markings are somewhat suggestive of D. tarsatus, but 

 the prothorax and tarsi do not agree with the description of that species. The 

 flavous portion of the elytra, and the legs, are slightly paler than the pale parts 

 of the prothorax and under-surface. On the males the spots on the prothorax 

 are placed at the apical third, are rounded and each is scarcely "bigger than an 

 eye; on the females they are much larger and transverse, almost touching the 

 sides, and on one are connected across part of the middle ; the dark markings at 

 the base of the elytra are irregular, Init little more than a basal edging; the post- 

 median fascia is not exactly alike on any two of the eight specimens under 

 examination, on one it touc'.ies the sides, on another it consists of hardly more 

 than a rather narrow transverse infuscation. crossing the suture for a short 

 distance, with a spot between each end and the margin; on one specimen the 

 median portion is connected with the left spot, but not with the right ; but it 

 usually has a zigzag appearance; the infuscations of the abdomen (including the 

 pygidium) are more pronounced on the males than on the females. The front 

 and hind angles of the prothorax, as viewed from the sides, are seen to be rectan- 

 gular, but from above the front ones seem to be rounded ofl:, and the hind ones 

 acute, and even to slightly embrace the shoulders. Owing to "waterlogging" the 

 >eriate punctures on the elytra, when viewed from above, appear to be of great 

 size, even wider than the interstices, but from oblique directions they are seen to 

 be only about one-third, or one-fourth, the width of the interstices.
