252 Eustace W. Fen/itson: 



Head strongly convex, rather feebly depressed in front; with a 

 few obsolete punctures. Rostrum short, excavate, external ridges 

 rounded across, subrugosely punctate, somewhat convergent pos- 

 teriorly; internal ridges prominent, convergent; median area 

 strongly depressed, sublateral sulci long, deep, connected at base by 

 ^-ransvere basal sulcus. Sulci well defined posteriorly; eyes ovate. 

 Prothorax (4.5 x 5.5 mm.) rather strongly dilatate on sides, apex 

 somewhat produced , above, ocular lobes feeble; disc with br(?ad, 

 shallow subapical transverse impression, median line traceable; 

 <^losely set with numerous small granules feebly depressed above, as 

 if slightly abraded. Elytra (9.5 x 7.5 mm.) rather widely dilatate 

 posteriorly, apex strongly and abruptly rounded, base feebly 

 -arcuate, angles marked but not produced ; with rather deep longi- 

 tudinal striae formed of small closely set transverse foveae, the 

 intervening ridges depressed, but running up on to the interstice 

 on eithei- side; interstices strongly raised, the .second tlie most 

 prominent, the first, second and third definitely costiform, the com- 

 ponent granules abraded to base level, the remaining interstices not 

 so evidently costiform, the granules, tliough showing a tendency 

 towards abrasion, small and distinct, on the fifth and sixth in 

 double series. Beneath, intermediate segments short; fifth with 

 extensive shallow depression reaching to anterior margin in middle 

 and extending to postero-lateral angles, also with a deep, slightly 

 transversely oval median fossa situated near posterior margin, a 

 blunt tubercle present at each side of, and propecting into, fossa, 

 situated a little neaier posterior than anterior margin, and nearer 

 to side than to corresponding tul^ercle. Anterior femora not 

 i-idged, tibiae simple.

Hah.—^.ii. Wales, Mt. Kosciusko, 6000 ft., 5th March, 1915. 



For the opportunity of describing this species I am indebted to 

 Dr. A. Jeffries Turner, wlio took the unique specimen on Mt. 

 Kosciusko in March, 1912. 



The species forms an interesting addition to the morbillosus 

 group, group xiii. of my revision. From the other members it is 

 readily distinguished by the costiform character of its elytral sculp- 

 tuif. In my table it might be placed next T. melnncholicus. Lea. 

 iuid the table Avould then read : — 



116 (111) Third elyti-al interstice costiform.
