before the middle, more narrowed in front than behind; the median 

 groove is deep and extends into the basal fossa, which is united to the 

 elongate lateral impressions by transverse striae, its sculpture seems to 

 be finely subgranular. Elytra, at the base, broader than thorax, a third 

 longer, without perceptible punctation ; sutural striae deep; dorsal im- 

 pressions deep at the base, rather broad, but becoming indistinct before 

 the middle. Hind-body deflexed posteriorly, much shorter than elytra, 

 its first visible segment horizontal, with a transverse basal impression. 



Legs very elongate, the frontal pairs particularly; femora rather 

 slender, anterior tibiae moderately curved externally. 



Antennae elongate, with slender pubescence, basal joint cylindric, 

 stout, red, distinctly punctate, nearly double the length of the oblong 

 2nd; joints 3-8 oblong, 3-5 slightly larger than the three which follow; 

 9th and 10th about equal, as long as they are broad, narrowed apically, 

 distinctly, yet not very much, broader than the 8th; terminal elongate, 

 conical, acuminate, and about as long as the 9th and 10th combined. 



The remarkably elongate, Byraxis-lihe legs, rather short deflexed 

 hind-body, suberect elytral vestiture, and the peculiar sculpture of the 

 head and basal joint of the antennae are sufficiently distinctive.

Greymouth. A single individual from Mr. J. H. Lewis. 



Byraxis Reitter. Beitrage zur Kafer-fauna von N.Z. Verh. Nat. ver. 

 Brunn., vol. 20. 



Near subgenus Jieicheubackia. Body rather short and convex. An- 

 tennae 10-articulate, robust, distant at base, almost biclavate. Maxil- 

 lary palpi quadriarticulate, terminal joint fusiform, narrow. Basal 

 joint of posterior tarsi short, the following two much elongated, with 

 single claws. Head obsoletely bifoveolate. Thorax smooth, not at all 

 foveolate. Elytra without dorsal striae.

p. 197. 



Rufo-castaneous, shining, smooth; extremity of antennae piceous, legs 

 red. 



Head nearly quadrate, almost plane, with 2 shallow frontal foveae. 

 Thorax about as long as broad, cordiform, smooth. Elytra smooth, with- 

 out dorsal grooves, sutural striae very fine. 



Male. — Antennae robust; basal joint stout, cylindric; 2nd quadrate, 

 narrower than 1st; joints 3—8 transversal, 7th and 8th appreciably 

 widened; 9th and 10th large, uneven, and pubescent, the former acutely 

 produced outwardly, the latter very thick, nearly sublimate inwardly, 

 so that the extremitv of the 9th joint can be received in the hollow. 



Penultimate ventral segment deeply impressed, the basal strongly 

 foveolate medially, crested and bifasciculate laterally. 



Length, 1*5 mm. 



Greymouth. Mr. R. Helms. 



3215. Byraxis rhyssarthra sp. nov. 



Smooth, shining, nearly glabrous, there being only a few incon- 

 spicuous greyish hairs on the hind-body; rufous; elytra, legs, and 

 antennae of a paler red; tarsi and palpi flavescent.
