14. Holocorynus longiceps, sp.n. 



Depressed, black, shining, the posterior angles and base of the thorax 

 narrowly reddish-testaceous. Antennae ferriigineous. Mandibles prominent, 

 black. Legs testaceous. Length 8*5 mm. 



Head oblong, much longer than broad, broader and almost as long as the 

 thorax, the sides exactly parallel, the posterior angles briefly rounded. Eyes 

 very small. Median frontal grooves superficial, parallel, rather long, posteriorly 

 with an umbihcate setiferous punctm*e ; lateral grooves short, oblique, com- 

 mencing at a large umbilicate puncture near the eye, and ending at the umbili- 

 cate puncture at the end of the median groove ; from the base nearly to the 

 apex with a narrow deep sulcus in the middle line ; on either side, for about the 

 anterior two-thirds, with a few elongate umbilicate punctures, the basal region 

 impunctate, the long temples with three or four punctures, the disc with a few 

 small punctures and with a fine, interrupted, longitudinal ground sculpture. 

 Antennae with the 2nd joint shorter than the 3rd, 3rd clavate, 4th shorter, 

 clavate, 5th to 10th sHghtly transverse. Thorax much longer than broad, 

 widest at the rounded anterior angles, the sides strongly narrowed to the 

 rounded posterior angles, the disc with four quadrately placed punctures and 

 with two others near the anterior angles, before the middle of the base with a 

 short impressed line, the whole surface covered with a vermiform ground sculp- 

 ture more or less transverse on the disc and longitudinal at the sides. Scutellum 

 mth two large setiferous punctures and transverse wavy ground sculpture. 

 Elytra as long as, but a little broader than the thorax, obsoletely impressed 

 behind the shoulder and before the apex, with a few very obsolete larger 

 punctures and an exceedingly fine irregular puncturation, without ground 

 sculpture. Abdomen practically smooth in the middle, the sides of the seg- 

 ments "with a few fine setiferous punctures. Posterior tibiae short, lightly 

 curved. The head in this species is much longer than in H. discedens Shp.
