Hab. — Western Australia: Cue (H. W. Brown). Type, 

 I. 2555. 



At a glance appears to belong to Titinia, but the pro- 

 thorax is distinctly bisinuate at the base. In some respects 

 it seems close to midtimaculatas, but the rostrum is differently 

 shaped, and the antennae are much thinner. In my former 

 table would have been associated with trilineatus, but the 

 pro thorax is without a dark median line. In many respects 

 it is close to fuscomaculatus, but the antennae are somewhat 

 longer, the eyes are not quite so prominent, and the sides of 

 the rostrum are slightly different. The clothing as described 

 may be of the males only. The numerous specimens taken 

 by Mr. Brown appear to belong to but one species, as struc- 

 turally (except for slight differences that are almost certainly 

 sexual) they appear to be all alike. But by the clothing, 

 markings, and apex of prothorax they may be divided into 

 four sections, although there are a few specimens that are 

 intermediate between two sections : — 



1. Prothorax usually feebly incurved at middle of apex, 

 with an irregular dark vitta on each side. Elytra with 

 numerous small dark spots, and usually with a large irregular 

 one on each side beyond the middle (this spot may be entire, 

 or simply a closely-set cluster of small spots). Elytra with 

 numerous, more or less erect, blackish setae. 



2. Scales of upper-surface of an almost uniform pale 

 slaty-grey. Elytra with erect dark setae on basal half, but 

 absent posteriorly. Apex of prothorax straight, or feebly 

 projecting in middle. 



3. Upper-surface with sharply contrasted markings, and 

 apex of prothorax as in Section 1 ; but elytra entirely without 

 suberect setae. 



4. Scales and apex of prothorax as in Section 2, but 

 elytra entirely without suberect setae. 



In all sections the scales on the under-surface frequently 

 have a golden lustre in parts. In. Sections 2 and 4, which 

 probably consist of females, the others probably consisting of 

 males, there are usually three whitish spots at the base of the 

 elytra, and occasionally there are some feeble pale spots scat- 

 tered amongst the slaty-grey ones. In all sections there are 

 a few pale depressed setae on the elytra, but they are more 

 distinct on 2 and 4 than on 1 and 3. Of fourteen specimens 

 of 1 and 3, there are not two with the spots exactly alike in 

 size and distribution.
