1 1 86. O. tectum, "--y- Body elongated, narrowed towards both 

 extremities, sub-depressed, rather densely covered with yellowish-grey 

 hairs ; reddish-castaneous. Legs more or less infuscate ; antennce ob- 

 scure-testaceous. 



Anic7in(e very long, extending backwards beyond the posterior femora, 

 slender, filiform ; basal joint stout, about half the length of the third ; 

 second and third short, the latter the longer, conjointly deoidedly shorter 

 than the following one. Head coarsely but not closely punctured, very 

 much depressed in front. Prothorax longer than broad, gradually nar- 

 rowed anteriorly, conical, its apex truncate, with the distinct angles not 

 perceptibly depressed, posterior angles long and divergent ; it is closely 

 punctured, with a median furrow from base to apex. Scutellum longer 

 than broad. Elytra elongate, punctate-striate, interstices slightly convex, 

 rugulose, apices simple. Under-side castaneous, rather densely punctured 

 and pubescent. 



The prosternal process is considerably elevated betv.xen the coxa^, and 

 the margins of the mesosternal cavity are rather fine, much more so than 

 in the typical species. ISIetasternum canaliculate. 



Length, 5-^- lines; breadth, nearly i-^. 



My two specimens, one mutilated, were found near Whangarei 

 Heads. 



Mecastrus lateristrigatus, '^Vhite. (8yn., 550, Eiater

Antennce long and stout, pubescent, black, second and third joints 

 short, equal, conjointly shorter than fourth; joints 4-10 acute inwardly at 

 the extremity. Head punctate. Prothorax longer than broad, narrowed 

 towards the front ; shining black, with rather long but fine dark-grey 

 hairs, rather finely and moderately closely punctured. Elytra black, with 

 a broad infuscate-red vitta on each near the side ; punctate-striate inter- 

 stices rugulose, closed with finer hairs than those on the thorax. Legs 

 black. $. 



Female. — Antennal joints 4-10 less acute at the apex, third longer than 

 second ; thorax closely punctulated, its posterior angles rufescent ; elytra 

 rather less evidently punctured, and their lateral stripes less obvious.

1 187. C. meinertsliageili, n.s. Elongate, sub-parallel, mode- 

 rately shining, covered with fine, short, yellowish-grey hairs ; fuscous, 

 head and thorax darkest, legs fusco-testaceous ; antenna, save the two 

 reddish basal joints, obscure-black. 



Head finely but densely punctate, transversely impressed just behind 

 the well-defined margin of the epistome, which is somewhat rufescent. 

 Prothorax longer than broad, convex, obtusely rounded near the middle, 

 a good deal narrowed behind, with prominent, divergent posterior angles ; 

 its whole surface is closely but not coarsely punctured, and is impressed 

 longitudinally. Elytra elongate, a little dilated posteriorly, the suture 

 somewhat elevated; finely punctate-striate, the interstices so sculptured as
