756 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



somewhat thinner, antennae thinner and depressions on prono- 

 tnm slightly larger and with a third one in middle. The elytral 

 markings are also very different; their flavous portion (which is 

 not of an uniform shade throughout, but in places has slight 

 infuscate stains) occupies about one-half of the surface; to- 

 wards the base on each elytron it is encroached upon by three 

 extensions of the dark portion, two of which are acutely tri- 

 angular; towards the apex it is also encroached upon by two 

 acutely triangular dark extensions; the suture is obscurely pale 

 almost to the base. 



Orchesia pictipennis, n.sp. 



Castaneous; pronotum black, parts of under surface infus- 

 cated, elytra with flavous and infuscate markings. Densely 

 clothed with short pubescence. 



Head with rather small but clearly defined punctures. An- 

 tennae rather short, apical joints clavate. Prothorax about 

 once and one half as wide as long, sides strongly rounded, base 

 truncate and much wider than apex; punctures as on head, mar- 

 ginal carina on each side curved and continuous throughout. 

 Elytra at base the width of prothorax, sides feebly dilated to 

 basal fourth, and then narrowed to apex, punctures as on pro- 

 thorax. JJnder-surface strongly ridged along middle. Hind 

 spurs distinctly longer than their supporting tibiae, and as long 

 as the following joint. Length, 3i-3| mm. 



Hab. — Tasmania: Mount Wellington, two specimens from 

 moss, Latrobe, one from flood debris (A. M. Lea). 



The pale elytral markings may be regarded as two zigzag 

 fasciae; of these the first is partly before and partly on the 

 middle, and consists of six irregular spots irregularly con- 

 joined; the second is at about the apical third on the suture, ami 

 on the apical fourth at the sides; they are rendered very con- 

 spicuous by the derm adjacent to them being deeply infuscated 

 (almost black). The specimen from Latrobe has much less con- 

 spicuous, markings than the others; on it the elytra slightly be- 

 yond the middle have an infuscate fascia, with the derm before 

 and after it considerably paler, but not flavous, although the 

 flavous markings of the type may be made out in a blurred 

 fashion. The elytra from some directions appear to be dis- 

 tinctly striated, but true striae (except for a vague subsutural 

 one on each elytron) are really absent.
