460 MR. R. E. TURNER oif [May 12, 



almost smooth. Mesopleurte rather finely rugose-striate. Median 

 segment much broader than long, narrowed towards the apex and 

 verticallv truncate posteriorly, shorter than the mesonotum ; a 

 large triangular space occupying almost the whole of the dorsal 

 surface very coarsely reticulate and enclosed by carmse ; the sides 

 of the segment striated, the surface of the posterior truncation 

 coarsely rugose. Abdomen smooth and shining, shorter than the 

 thorax and median segment combined. Legs not spmose. 



Black; the mandibles (except the extreme apex), the scape of the 

 antenna, the apical half of the femora, the tibiae above, and the 

 tegul^e yellow; the apex of the mandibles, the flagellum, the 

 abdomen, the base of the femora, the tibife beneath, and the tarsi 

 ferruginous. Wings hyaline, nervures pale ferruginous. 



The second cubital cell is more pointed on the radial nervure 

 than in H. steindachneri Kohl, from which it may also be dis- 

 tinguished by the small triangular truncation at the apex of the 

 clypeus, the larger head, which is much more produced posteriorly, 

 and the absence of a visible pronotum above. It is somewhat 

 intermediate between H. steindachneri and H, arator, but is 

 nearer to the former. 



Length 7-8 mm. 



Hah. Mackay, Queensland {Turner). 



Harpactophilus sulcatus, sp. n. 



§ . Clypeus triangular, convex, with a longitudinal carina from 

 the base not quite reaching the apex, where there is a very small 

 oblique triangular truncation. Mandibles feebly bidentate at the 

 apex, the outer tooth a little the longest. Antennse a little longer 

 than the head, the length of the scape equal to nearly half the 

 distance between the eyes at the insertion of the antennae ; the 

 first four joints of the flagellum much longer than broad, the 

 second joint twice as long as the first and more than half as long- 

 again as the second. Head very lai'ge, coarsely longitudinally 

 striated, the strife curving round the summit of the eyes, a narrow 

 depressed line divided by deep punctures round the mai'gin of the 

 eyes, the small space between the eyes and the base of the 

 mandibles smooth. The posterior ocelli nearly twice as far from 

 the eyes as from each other and about the same distance from the 

 posterior margin of the head as from the eyes. The posterior 

 margin of the head depressed and broadly emarginate. Pronotum 

 depressed below the mesonotum ; the mesonotum about one-third 

 narrower than the head, about half as broad again as long, 

 coarsely longitudinally striated in the middle, coarsely rugose on 

 the sides. Mesopleurse obliquely striated ; scutellum almost 

 smooth. Median segment a little shorter than the mesonotum, 

 the large enclosed triangular area on the dorsal surface very 

 coarsely rugose, the segment strongly narrowed to the apex and 

 vertically truncate posteriorly, the sides coarsely striated. 

 Abdomen shining and almost smooth. The carina on the front 

 of the head, between the grooves for the scape, is less strongly 

 developed than in the allied species.
