pallida) but much smaller, and with a broad biaek fascia on the 

 hinder part of the elytra wliich is prolonged along the suture 

 towards the apex." The description of IS. pallida is a similar 

 comparison of that species with .V. Mastersi, and the description 

 of aS. Masiersl (as noted above) a similarly brief comparison with 

 aS^. posticalis. There is not much in the above to assist identi- 

 fication, but I remt-mber seeing the type of fasciata some years 

 ago at Sydney and recognise the present species as at any rate 

 considerably resembling it. The species that I therefore call 

 " E. faisGiaia^ Macl (?)" is entirely testaceous except some fuscous 

 colofiiig (not always present) along the front of the pronotum 

 and the sides of the abdomen, and on the elytra a dark sub- 

 basal spot on either side near the scutellum and a dark marking 

 behind the middle the form of which is difficult to describe; the 

 second interstice is dark from the middle tor about two thirds of 

 its distance thence towards the apex, the third and fourth in- 

 terstices are dark from about the beginning of the apical one- 

 third of their length to about the beginning of the apical one- 

 fourth, the fifth interstice is dark on a still smaller space, and 

 the sixth interstice is dark from about the middle of its length 

 for about one-half its distance thence to the apex; the first in- 

 terstice is slightly infuscate on the part corresponding to that 

 which is dark fuscous on the second interstice. Thus the dark 

 portions of the interstices form a kind of common fascia extend- 

 ing from the sixth interstice on one elytron to the same on the 

 other elytron, which fascia is strongly trifid on its front margin 

 and jaggedly arcuate on its hind margin. The above markings 

 scarcely vary in the dozen specimens that are before me. The 

 granulation of the eyes, insertion of antennae and coriaceous 

 subopacity of the pronotom do not seem to differ much from the 

 same in the preceding species. The prothorax is wider than in 

 the allied species, its width being to its length almost as one and 

 two-thirds to one. The striation and interstices of its elytra are 

 not noticeably difTerent from the same in grave. The tarsi very 

 closely resemble those of grave, with the exception that the 

 fourth joint of the hind pair is notably longer, being quite dis- 

 tinctly more than one-half the length of the preceding joint. 

 I possess besides the specimens described above two examples of 

 an Ectroma from South-west Australia (Eucla) which I take to 

 represent a variety of the same insect as I can find no difference 

 except in the markings of the elytra which are almost exactly 

 as in the species that I have (above) called " E. inquinata, 

 Er. (?)." Of the two forms this latter (from Eucla) seems to 

 agree more exactly than the other with Macleay's quasi-descrip- 

 tion. 



It is perhaps possible that the insect described above is that
