land, opposite Double Island (10 or more miles north of Cairns) 

 I captured a male Scelio which is undoubtedly this species. It 

 is both like ovi and australis, but the striation along the dorsal 

 and ventral aspects of the abdominal segments is rugolose, the 

 striae curved and interlacing around punctures and hence shorter 

 and not nearly parallel; the antennas in this specimen are wholly 

 honey-yellow, but otherwise like those of the males of ovi. The 

 strong striae converging toward the mouth are conspicuous; the 

 proximal tarsal joint in the posterior legs is decidedly shorter 

 than with either ovi or australis, arid "the size is smaller (at least 

 with this specimen). The parapsidal furrows distinguishable, as 

 distinct as in the other species noted (ovi and australis). 



There are six species of the genus now known from Australia, 

 all parasitic upon acridiid eggs. I give herewith a diagnosis of 

 them, constructed from the literature and the foregoing specimens. 

 The three species occurring in Queensland are distinct from the 

 three known from New South Wales and this is expected from 

 the difference in latitude. 



KEY TO THE FEMALES OF THE AUSTRALIAN SPECIES OF SCELIO LATRE1LLE. 



Black, the legs reddish brown or yellow, the fore wings infuscated. 



I. Head smooth, polished, with a few scattered, fine punctures or 



a few converging striae. . 



Scape, pedicel, and at least first two or three j oints of f unicle 

 fulvous; segments 1 and 2 of abdomen longitudi- 

 nally striate, segment 3 finely reticulate, segment 

 4 with similar sculpture at base, the succeeding 

 segments hardly sculptured; ventral segment 3 of 

 abdomen with punctures on each side of meson 

 and segment 4 with the same punctures but cover- 

 ing a smaller space. Face without striae 



pulchellus Crawford 



Scape, pedicel, proximal and apical f unicle joints fulvous; 

 abdominal segments all finely, longitudinally stri- 

 ate, but the fifth segment with a median smooth 

 area and ventrad the segments all having the 

 middle of each smooth; face with some strise; 

 abdomen dark brown fulgidus Crawford 



II. Head rough, rugose or rugoso-punctate for a large part, 



especially at the vertex. 



(1) Abdomen wholly longitudinally striate or rugulose, dorsad 

 and ventrad, except maybe medially and at the 

 incisions of the segments. 



Abdomen longitudinally striate; parapsidal furrows dis- 

 tinct.
