84 REVISION OP SYMPETES AND HEL^US, ETC., 



humei'al callus prominent and a lens prominent convexity half 

 way, closely dotted with shallow punctures : disc with suture 

 strongly carinate throughout, and five fairly definite smooth 

 costse on each elytron; of these the first is a short postscutellary 

 costa parallel to the sides of the scutellum, the next three, parallel 

 and equidistant, extend from the humeral region, obliquely 

 approach the suture, becoming obsolete on apical declivity, the 

 fifth subobsolete, half-way between the fourth and the outside 

 of disc; junction of disc and margins marked by a line of large 

 punctui'es in a depressed line, these most evident towards cipex, 

 the extreme border of disc itself a little raised and crenulate; the 

 intervals between costse faintly rugose, coarsely and irregularly 

 punctured. Abdomen finely and closely, underside of foliate 

 margins coarsely punctulate, tibiae armed at apex with two spines, 

 one very long, under surface of legs rugose, tarsi and lower parts 

 of tibiaj clothed with yellow hairs. Dimensions— 19 x 16 5 mm. 



//«6. — Shark Bay, West Australia; sent by Mr. C. French. 



I have two specimens, both, I think, ^, generously presented 

 by Mr. French. While evidently very close to S. acutifrons Lea 

 (from Geraldton), the dimensions, especially the proportion of 

 length to width, diff'er sufficiently to make a clear distinction; 

 moreover, in Lea's species the margins are testaceous, while in 

 S. hicolor they are a distinct cream-yellow in both specimens; .S'. 

 acutifrons Lea, is described as having elytral interstices "irregular, 

 feebly raised," in S. hicolor the costal are evident. Type in 

 author's coll. 



I have since compared it with liea's type, and find it evidently 

 distinct in (1) the much stronger contrast of colours in disc and 

 margins; (2) the much wider form, especially of explanate 

 margins; (3) wider head with more truncate epistoma. 



Sympetes quadratus, n.sp. 



Widely and squarely oval, dull brownish-black, tarsi and upper 

 surface of antennae red. 



Head wide, a little convex, with epistoma squarely truncjile and 

 overlapping the labrum, front angles squarely rounded and a
