358 Mr. R. S. Bagnall on some 



number of strong spines set in warts. Eyes large, finely 

 facetted, bulging anteriorly and apparently extending further 

 on under side than on upper. Ocelli large, posterior pair 

 on a line with centre of eyes and close to their margins, widely 

 separated from the anterior ocellus, which is borne between 

 two spine-bearing warts midway betwixt the extreme apex 

 of head and the anterior margin of eyes. Ayitennce inserted 

 above the apex ; joints 3 to 6 elongate and claviform, 7 and 8 

 fusiform. Third joint tw ice the length of the two basal joints 

 together, fourth four-fifths of third, fifth three-quarters of 

 fourth, sixth much shorter than the preceding and equal in 

 length to the penultimate and apical joints together. An- 

 tennal spines at the apex of each joint very long, especially 

 on the outer side, dark brown ; sense-cones light and therefore 

 inconspicuous, slender and acute, at least two on each of the 

 joints 3 to 7, three or more on the fourth. 



Prothorax one-third as long as head, disk deeply sculp- 

 tured, upper surface strongly narrowed from middle to base, 

 and two large tubercles, set low down, forming posterior 

 angles, and another pair within and above this pair ; each 

 anterior angle produced, thus forming a very strong recurved 

 horn, which is striated transversely and bluntly toothed near 

 apex. 



Anterior coxa not greatly enlarged, plainly reticulate, and 

 armed with one fairly conspicuous spine. Fterothoi-ax much 

 broader than head, apparently longer than broad, with ineta- 

 sternum laterally rounded, narrowed, and armed with several 

 strong white bristles. Wings present, short in comparison 

 with the great length of the body, apparently reaching to fifth 

 abdominal segment. Legs long : fore femora much enlarged 

 and each armed with a strong tooth which has its base above 

 the mid-line beneath ; fore tibise broad and flattened, one or 

 two small blunt teeth at apices and each fore tarsus armed 

 with an exceedingly stout long tooth. Intermediate legs 

 comparatively slender, set with a number of long light- 

 coloured bristles. 



Abdomen simple, extremely long and slender, being two- 

 thirds the length of the whole insect and about one-eighth as 

 wide at base as it is long. Tapered very gradually to tube. 

 Tube only two-thirds the length of ninth abdominal segment 

 and only one-third the length of head ; terminal hairs short 

 and weak, and spines on abdomen comparatively sliort. 

 Surface transversely striate and in parts plainly reticulate. 

 Type. One male in British Museum (ex coll. Sauudersj. 

 Hab, Dorey, New Guinea {Wallace).
