thickened towards the apex, which is notched, the 2nd a little shorter than 

 the 3rd, the 4th and 5th scarcely longer than broad, the 6th to the 10th trans- 

 verse, gradually increasing in width, the 11th elongate, oval, as long as the 

 two preceding joints together. Thorax strongly transverse, a little broader 

 than the head (including the eyes), the anterior margin sinuate on either side, 

 the sides rounded and contracted from the anterior angles to the base, in which 

 they merge evenly ; the disc with a deep narrow groove extending from the 

 anterior margin in the middle line to just in front of the posterior margin; 

 puncturation crateriform, moderately coarse and rather close ; pubescence stiff, 

 yellowish ; the sides viewed from above present posteriorly one or two crenu- 

 latious. Scutellum impunctate. Elytra broader than and about twice as long 

 as the thorax, square, closely covered with puncturation and pubescence of a 

 similar character to that of the thorax. Abdomen finel}'^, evenly, and sparingly 

 punctured throughout (excepting the last segment, which is very sparingly 

 punctured), the punctures being of the same character as those on the head 

 and prothorax, but much finer ; pubescence as on the fore-parts.

Philoiitlius onifiventris, n. sp. 



Black, shining, the thorax, base, suture, and apex of the elytra, and abdomen 

 (except the 7th and 8th segments), red ; thorax with a dorsal row of 5 punc- 

 tures (Erichson's notation) on either side of the middle line ; the first three 

 and last two joints of the antennae and the legs reddish-testacecus. Length 

 5*5 mm. Of the build of P. crassicornis Fauv., to which group it belongs, but 

 at once distinguished by the coloration. Head black or pitchy-black, quadrate ; 

 the eyes rather small, their diameter about the length of the temples, which 

 are very slightly convergent to the rounded posterior angles ; the median intra- 

 ocular punctures widely separated from each other and close to the lateral 

 ones ; the disc with two punctures posteriorly, one on either side of the middle 

 line, and two or three near the posterior margin of each eye. Antennae short 

 and stout, the penultimate joints less transverse than in P. crassicornis ; the 

 3rd joint a little shorter than the 2nd, the 4th a little longer than broad, 

 the oth square, the 6th to the 10th transverse, but not increasing in width, the 

 11th short-oval. Palpi reddish-testaceous. Thorax red, a little longer than 

 broad, the sides nearly parallel, the disc on either side with a row of five 

 medium-sized punctures, the sides with three or four others ; no visible 

 ground-sculpture present, as on the head. Scutellum triangular, pitchy, with 

 about a dozen rather large punctures. Elytra about as long as the thorax, 

 quadrate, the base broadly rufous, the suture and apex narrowly reddish- 

 testaceous ; very finely and sparingly punctured ; pubescence rather long and 

 sparing. Abdomen, with the exception of the greater part of the 7th and the 

 whole of the 8th dorsal segments (which are pitchy), red, with a very few fine 

 punctures ; pubescence rather long, stift', and scanty. First joint of the 

 posterior tarsi as long as the last. 



S . Head broader, anterior tarsi more dilated ; sixth ventral segment 

 with an acute triangular impression, the sides of which are bounded by a fine 

 raised line, and the base (which corresponds to the posterior margin of the 

 segment) obtusely emarginate.
