 Territory: Daly River (H. Wesselman), Melville Island (G. F. Hill, No. 3461). 

 Type, L 12008. 



Allied to E. erichsoni and E. austraUac, but with very ditiferent elvtral 

 markings; these, from directly above, appear to be in alternating red and black 

 bands ; of the red ones the first occupies the basal two-fifths, except for a large spot 

 (varying from semicircular to transversely oblong) about the scutellum, and a 

 narrow space (invisible from above) on each side, it usually has a short extension 

 on the suture ; the second is median, somewhat oblique, rather narrow, and extends 

 neither to suture nor sides ; the third is at the apical fourth, slightly longer than 

 the second, is usually, but not always, interrupted at the suture, and terminates 

 before the sides ; the scutellum is usually obscurely diluted with red. The Daly 

 River specimen has the middle of the apex of prothorax obscurely reddish, and 

 the red still more ()l)scurely traeealile along the middle to base.

Plate iv, fig. 6. 



Black; sides of prothorax, elytra (four black spots excepted), most of 

 abdomen, tarsi, middle coxae and palpi more or less red. Moderately densely 

 clothed with rusty-red pubescence. 



Head with sharply defined punctures of moderate size. Antennae with third 

 joint about once and one-half the length of fourth, joints of the club not twice the 

 width of the others. Prothorax about twice as wide as its shortest length, sides 

 obtusely serrated, apex truncated in middle and notched near each side, the 

 commencement of each notch marked by a slight tubercular swelling ; punctures 

 more irregular than on head, and leaving a shining median line. Elytra parallel- 

 sided to near apex ; with regular rows of fairly large punctures, becoming smaller 

 posteriorly, the interstices earh with a row of small ones. Intercoxal process of 

 prosternum rather wide, posterior end obtuse. Coxal lines of abdomen traceable 

 to beyond middle of first segment. Length, 5-.")-6-.l mm.
