1410 COLEOPTEKA 



Head narrower than the thorax, its sides strongly elevated near 

 the antennal insertion, distinctly punctured ; clypeus and mandibles 

 reddish, the former minutely punctate. Antenna stout, elongate, 

 the last five or six joints with more conspicuous yellowish pubescence 

 than the others, the basal two nearly glabrous ; third much longer 

 than second, joints 3-11 with a distinct rim at the base. Thorax 

 narrower than the elytra, about as long as broad, base truncate, 

 apex slightly sinuate, widest before the middle, the sides a little 

 narrowed, but nearly straight behind, posterior angles rectangular ; 

 its surface uneven, moderately coarsely punctured. Elytra as long 

 at the sides as they are broad, the apices obliquely cut away towards 

 the suture ; on each elytron, near the middle, there is a large tuber- 

 cular elevation ; they are so sculptured as to appear punctate-striate, 

 the interstices are elevated for the most part, but, behind, some of 

 them are flattened and more distinctly punctured than they are 

 near the base. Abdomen elongate, more or less finely punctured, 

 the three basal segments with the lateral margins a good deal 

 thickened behind, third with a transverse impression near the 

 base, and two small, but distinct, tubercles near the apex ; second 

 segment similarly tuberculate ; the penultimate with a sharply- 

 raised, laterally-compressed elevation behind ; sixth rufescent. 

 Tibia nearly straight, with short, erect, slender, reddish setae. 



Female. Elytra and hind-body without tubercles, the former 

 with the second, third, and fifth interstices rather broader than the 

 others. 



The male may ' be easily known by the armature of the elytra 

 and abdomen. 



$ . Length, 3J lines ; breadth, J- line. 



Capleston, Westland. Mr. M T. Cavell was kind enough to 

 send me two ; the female, however, had been decapitated. 



Group HOMALHXffi. 



Homalium (Gen., p. 115). 



2458. H. tenellum, n.s. Slender, subparallel, slightly nitid ; 

 pubescence yellow, distinct, much shorter on the elytra ; pale-cas- 

 taneous, head and thorax slightly rufescent, the basal portion of the 

 elytra infuscate, the apical yellowish ; legs testaceous, the middle of 

 the tibiae more or less infuscate. 



Head widest in line with the prominent eyes, between these there 

 are two well-marked, rounded foveae, its punctuation is distinct but 

 not close. Antenna with the basal joint quite as long as the fol- 

 lowing three taken together ; second stout, oviform ; 3-5 bead-like, 

 third longer than broad, these three joints paler than the others ; 

 sixth rather larger than the fifth ; 7-10 transverse ; eleventh conical ; 

 the last six joints bear erect fuscous hairs. Thorax nearly as long 

 as broad, its sides nearly straight behind but well rounded towards 

 the front, the posterior angles rectangular ; there are two depres- 

 sions behind the middle, and a small one at each side, it is distinctly 

 but not closely punctured. Elytra quite oblong, the sutural region
