curve short; strife strongly impressed, eighth well marked in all 

 its course ; interstices a little convex, becoming narrow and 

 decidedly convex towards apex, second wider near base and with 

 a well marked basal striole rising from base of second stria, ninth 

 narrower than eighth in middle of length, wider towards apex; 

 lateral border reflexed. 



Length 3-7, breadth 1-5 mm.

Differs from the other species of Thenarntes by having a well 

 marked striole at base of second interstice of elytra. Its facies 

 is that of Thenarotes, but perhaps it is not in its proper place in 

 that genus, though it does not come into any other Australian 

 genus. The characters that define the genus Thenarotes are a 

 little doubtful ; the type ( T. tasmanicus, Bates) is fully striate 

 and has the mentum toothed in the sinus; Th. australis, Blkb., 

 has the elytra with the strife obsolete on the sides, the mentum 

 edentate and the ^ without spongiose tissue beneath any joints 

 of the four anterior tarsi. Th. brnnnicolor has the mentum 

 edentate but the elytra full}'' striate (the tarsal vesture of the ^ 

 unknown). Perhaps the characters of the genus may vary 

 sufficiently to include all these differences, in which case Th. 

 tasmanicus, Th. australis and Th. brunnicolor would represent 

 three groups in the genus, but it may be found necessary, when 

 the classification of these and allied Harpalids is fully worked 

 up, to place each of these species in a separate genus. 



I^ote. — Only that the basal angles of Th. brunnicolor are widely 

 rounded, the sides would meet the base almost at right angles. 



Genus Euthenarus. 



This New Zealand genus is represented in Australia, and at 

 least one species, viz., E. ( AcupaJpus) morganensis, Blkb., has 

 been described. I have compared Acupalpus morgnnensis with 

 E. brevicollis, Bates, and E. puncticoUis, Bates, the New Zealand 

 species for which Mr. Bates founded the genus, and have found 

 it congeneric with them.
