apical central fovea, the medial line apparent on front half.. 

 Scutellum wide, curvilinear triangular, minutely punctate. 

 Elytra 15 x 11^ mm., less wide than prothorax at base, humeral 

 angles obtuse ; sides subparallel on basal half, widening behind, 

 and not at all sinuate at apex ; explanate margins narrow 

 throughout with narrowly-reflexed border ; each elytron with 

 four equidistant costse, the last on the sides, besides the sub- 

 costate alternate intervals, and seventeen rows (besides a short 

 scutellary row) of large squarely-cut punctures, separated by 

 raised subreticulate intervals ; the punctures larger and 

 rounder on sides, smaller and subobsolete at extreme apex. 

 Abdomen with basal segments coarsely, the two apical segments. 

 minutely punctate, the larger punctures of the former bearing 

 short erect reddish hairs; meso- and metasternum similarly 

 clothed, the prosternum, episterna, and epipleurge quite smcoth, 

 posterior intercoxal process acutely triangular. Tibiae, punctate, 

 their interior edge pilose, the front and intermediate tarsi with 

 three, the posterior with two basal joints greatly enlarged, 

 and padded beneath with red tomentum. Dimensions— 

 23 xllj mm.

A single specimen, male, in the National Museum, Mel- 

 bourne, presented by Captain Sumter, is the finest and most 

 easily identified of the group to which it belongs, sect, ii., sub- 

 sect. i./ 1 ) by the following characters: — (1) Strongly dentate 

 anterior angles of prothorax (even more so than the very 

 different in other respects acuticollis, Macl., or spinicollis, 

 Macl.) ; (2) coarsely punctate elytra (the series contain larger 

 punctures than in any Pterohelams known to me, and these 

 so closely packed as to be contiguous except for the raised 

 intervals) ; (3) the abnormally-enlarged basal- joints of the tarsi 

 (it is a pity that a female specimen is not at hand to see how 

 far this is merely sexual ; I have seen nothing like it in the 

 whole genus). 



Pterohel^eus rubescens, n. sp. 



Ovate, more than usually convex; dark reddish-brown 

 above, with a primrose bloom ; palpi and tarsi a shade lighter ; 

 underside a shade darker. 



Head closely and clearly punctate; labrum prominent; 

 epistoma straight in front, sides oblique, raised and continuous 

 with canthus ; tumid and convex anteriorly, depressed on fore- 

 head ; the separating suture arcuate and distinct ; eyes close 

 (separated by a distance equal to the length of the first anten- 

 na! joint); antennae not reaching base of prothorax, 3 not as 

 long as 4-5 combined, 8-10 oval not transverse, 11 twice as
