1008 COLEOPTEEA 



considerably nalTO^ved behind, posterior angles quite obtuse, lateral 

 margins simple ; basal fossas small and elongate, placed close to the 

 angles, disc evenly convex, ^vithout well-marked median groove, but 

 with the common frontal impression, densely and minutely sculp- 

 tured, much more finely than the head, and with a few obsolete 

 transverse wrinkles. Elytra oblong -oval, striate - punctate, the 

 punctures rather coarse ; the sutural and larteral stria?, reach the 

 apices, but the other sculpture ceases in line with the hind thighs ; 

 third interstices bipunctate, the anterior punctures large and shal- 

 low\ Tarsi with the first two joints dilated and strongly produced 

 inwardly at the extremity, first joint very large. Palpi with white 

 setffi. 



Must be located near B. anclionoderum, but most nearly re- 

 sembling B. custictuin, from which it differs in having more oblong 

 ■wing-cases, obtuse thoracic angles, larger eyes. Sec. 



3'. Length, 2 lines; breadth, f line. 



One of the numerous discoveries of Mr. George Munro, near 

 Clevedon, Southern ^Yairoa, Auckland. 



1807. B. diaphanum, n.s. Nitid, robust, moderately convex, 

 finely shagreened ; head, thorax, and scutellar region aeneous 

 (greenish) ; elytra with some ill-defiued spaces also aeneous, the 

 rest of their surface a sort of ivory-white ; mandibles fusco-rufous ; 

 palpi, four basal joints of antennae, and the legs, almost trans- 

 parent white, remaining antennal joints slightly infuscate ; knees 

 and tarsi tipped with testaceous. 



Head large, with large uneven frontal impressions. Ei/cs large 

 and prominent. Palpi stout, terminal joint needle-shaped, the 

 penultimate large, with white setae. Thorax cordate, strongly 

 rounded laterally, considerably contracted behind, posterior angles 

 not well marked ; the dorsal groove extends almost from base to 

 apex, there is a curved impression near the front, several fine undu- 

 lating transverse striae on the disc, the front and base are feebly 

 longitudinally striate, the basal fossae are narrow and close to the 

 sides ; lateral margins a good deal widened near the middle, but 

 quite obsolete near the front and basal angles. Elytra ovate, more 

 narrowed behind than at the shoulders, which are rounded, margins 

 narrow near the base, gradually but considerably expanded pos- 

 teriorly, apical sinuations feeble ; they are distinctly punctate- 

 striate, the two sutural striae of each elytron are confluent and reach 

 the base, the others do not ; the punctuation becomes obsolete be- 

 hind, but the strite are not obliterated there; interstices broad, 

 rather flat, the third with three setigerous punctures. Legs elongate, 

 rather slender, hind tibiae slightly incurved ; anterior tarsi stout, 

 basal joint elongate rather than oblong, strongly produced at the 

 extremity, second short, its inner angle similarly prominent, hind 

 tarsi elongate. Underside pale-fuscous. 



In form somewhat similar to B. musm, rather larger and bi'oader, 

 and with more elongate legs. 



^. Length, 3; breadth, nearly 1{ lines.
