its apex, rounded at tip, paler and spongy in texture and with short but coarse 

 close-set hairs in addition to the sparse erect bristles. Labrum very short, 

 strongly transverse; mandibles small; eyes large, rounded, entire and basal, 

 the antennal grooves altogether obsolete; mentum rather large, transversely 

 subquadrate; ligula triangular, corneous; palpi rufous, similar, the labial a 

 little smaller, the fourth joint elongate-oval, as wide as the preceding, with 

 the obliquely truncate apex hollowed and spongy. Prothorax slightly elongate, 

 very convex with a coarse deep median groove which is dilated anteriorly in a 

 large and deep excavation and slightly dilated also at the base, the polished 

 surface enclosing the groove prolonged anteriorly over the head in two porrect 

 processes, finely, sparsely punctate, each puncture with a minute seta, the setae 

 more evident at the apices of the processes; flanks above strongly declivous to 

 a deep groove adjoining the acute lateral margin, which groove is dilated in a 

 rounded excavation just behind the middle; lateral margins nearly straight, 

 feebly convergent from apex to base, the apical angles dentiform and everted; 

 basal angles acute and slightly prominent. ScuteUum small, subquadrate. 

 Elytra about twice as long as wide and twice as long as the prothorax, not 

 wider than the apex of the latter but a little wider than the base, the sides 

 straight and parallel ; apex semicircularly obtuse ; surface evenly cylindrical, 

 impressed at the sides near the apex, with nine coarse even and feebly im- 

 pressed series of coarse perforate punctures, the sutural stria enlarged and 

 deeper toward tip, becoming confluent with the subapical depression at the 

 side, the coarse punctures nude but alternating with minute punctures, each of 

 which bears a minute hair. Prosternum long before the coxse, the latter 

 moderately and almost equally separated throughout; anterior cavities open 

 behind. Legs very short and stout; tarsi short with the basal joint small. 

 Length 2.9 mm. ; width 0.75 mm.

No indication of sex can be observed in the single specimen 

 before me, which was communicated by Mr. H. F. Wickham.

Ditoma 111. ; Synchytodes Cr. 



The following species is allied to ornata: — 



B. suffusa n. sp. — Elongate, strongly depressed, opaque, dark rufo- 

 piceous, the elytra suffusedly pale rufous but darker near the suture and lateral 

 margin; pubescence short, sparse, setiform, forming even recumbent series 

 along the ridges. Head rather small, % as wide as the prothorax, subquad- 

 rate, the eyes large, convex and prominent, occupying basal half; surface flat 

 and densely sculptured; antennae about as long as the width across the eyes, 

 the funicle slender, the club stout, compressed and very abrupt, with the two 

 joints subequal. Prothorax scarcely ^^ wider than long, the sides feebly con- 

 vergent and feebly, evenlj' arcuate from apex to base; apex truncate, the 

 angles somewhat anteriorly prominent; basal angles obtuse; margins minutely 

 serrulate; base feebly arcuate; disk but feebly elevated, with a fine entire
