whence they taper gradually to the pointed apices, most prolonged in 

 the male, but not divaricate ; their surface is coarsely sculptured, deeply 

 striated almost to the apex, and marked with large punctures. The 

 underside is very glossy, with spots of tawny tomentum on the sides of 

 the breast and abdomen. 



Auckland (Mr. Lawson) ; a few examples. 



Note. — I possess a variety of a very elongate form, which is beauti- 

 fully marked with spats of orange-coloured pubescence. It occurs at 

 Tairua, and may perhaps be considered a distinct species, intermediate 

 between X. riigicol/is and X. niidiis. 



1038. X. inornatus, n.s. T/w?-ax elongate-quadrate, moderately 

 convex, rather wider in front than behind, slightly curved laterally ; the 

 disc is nude and slightly rugose transversely, the sides regularly clothed 

 with griseous pubescence. The elytra are of about the same width at 

 the base as the prothorax, and are widest near the middle ; the apices 

 are individually rounded, but not pointed as in X. riigicollis ; the punc- 

 tation is confined to the basal half, and is disposed almost in double 

 rows ; there is only one distinct stria, which is impunctate and situated 

 close to the suture, the rest of the surface bearing scarcely perceptible 

 furrows and ridges ; the clothing consists of short grey hairs, which are 

 evenly distributed over the surface, and never in patches. 



This form, though resembling X. rugiwllis, is nevertheless (juite 

 distinct from it ; it is altogether broader, more regularly sculptured and 

 clothed, and of a duller colour. 



Length, 5^ lines. 



I found several specimens at Tairua. 



1039. X. IsetUS, White; Voy. Er. Terr., Ins., p. 22. Base of the 

 elytra with several punctures, margin of suture with a few depressed 

 warts ; head and antennce ferruginous, with many greyish hairs, joints of 

 the latter (from the fourth) ringed with black at the end; thorax shining 

 violet, somewhat rough on the sides, with some spots covered with 

 yellowish hairs ; elytra shining green, sprinkled over with short grey 

 hairs ; scutellum and a few small spots across the elytra covered with 

 yellow hairs ; abdomen beneath smooth, polished, deep brown ; the 

 sides spotted with yellow ; legs somewhat violet, with short grey hairs. 



Port Nicholson (Capt. Parry). 



Note. — It is rather shorter and broader than any of the preceding, 

 with rounded apices. The colour is very variable, sometimes purplish 

 or greenish, but always metallic ; it seldom exceeds four lines in length, 

 usually three lines. 



1040. X. gratUS, n.s. Head rather narrow, with six or more 

 patches of yellow tomentum. Thorax sub-quadrate, impunctate, with a 

 transverse impression near the base and a similar one in front ; its sides 

 bear patches of tawny-yellow pubescence. Elytra sub-ovate, impunctate, 

 plane, apices rounded ; the clothing consists of several small patches of 

 bright pubescence (yellow) near the base, an irregular fascia beyond the
