and 7 subequal in length ; the club a little longer than the three 

 preceding joints, and with joint 1 distinctly longer than 2. Pro- 

 thorax nearly as long as bro:id (5 : 6), broadest at the base, the 

 sides gently rounded, the apical constriction shallow, the a.pical 

 margin truncate dorsally and with feeble postocular lobes ; the 

 upper surface with shallow reticulate punctation and occasionally 

 with a faint central carina. Scutellimi a little longer than broad. 

 Elytra with the lateral margins not sinuate, the apices jointly 

 rounded, the sutural impression moderately deep and quite asym- 

 metrical, being almost entirely confined to the right elytron and 

 extending backwards to the top of the declivity, and the apical 

 third of the suture set with raised interlocking black bristles. 

 Legs moderately long, thinly clothed with white setifoimn scales ; 

 the hind femora shortly exceeding the apex of the elytra, the 

 femoral teeth rather long and sharp ; the tibiae with the dorsal 

 margin straight and the basal sinuation veiy shallow. Venter of 

 S with two tufts of fairly long yellowish setfe on the apical 

 margin of segment 5 ; the pygidium with dense erect blackish

17. Balaninus consooius, sp. n 



S ■ Vei-y closely allied to B. trinotatus, sp. n., and apart from 

 its larger size, differing only in the following characters : — The 

 club of the antennae proportionately smaller, being a little shorter 

 than the three preceding joints ; the pi'othorax distinctly more 

 transverse ; the elytra with a post-median patch of white scales 

 on interval 3 similar to that on 2, but a little shorter, without 

 any white scales on interval 1 and with the sutural bristles 

 entirely black ; the fifth ventral segment of the J with the 

 apical tufts composed of very short setaj and a single long one. 



Length, 5' 2 mm. ; breadth, 3 mm.

(5 5 • Black, subnitid, thinly clothed above w^th narrow white 

 and light bro^vn scales, and wdth markings formed of broader 

 white scales ; the pronotum with about a dozen broad white 

 scales at each basal angle ; the scutellum w^th dense white scales; 

 the elytra with a po.stmedian macular wh:'te band lying between 

 stria 1 and 8 or 9 ; the sternum clothed with separated white

 eye in both sexes. Rostrum — S ■, shorter than the body (3 : 5),
