If he used all the specimens of each species before Mm in 

 drawing up his description, then all such specimens were 

 properly cotypes {strictu sensii), specimens equally historical 

 with single types, and which should not be separated. 



The matter should be cleared up without delay, and a 

 definite pronouncement made as to where the types of these 

 four species are. Perhaps the best course would be to assemble 

 at one or other Museum all the specimens of each of these four 

 species, and, if found in agreement with Mr. Tepper's descrip- 

 tions, to regard them as cotypes, placing an additional label on 

 each, clearly showing what has been done and when. 



As regards Ischnoptera hrunneonigra, Tepp., the Melbourne 

 and the Adelaide specimens are both females. The male, 

 which has never been described, I discovered at Healesville, 

 in Victoria, and now append a description of it : — 



Sub-Family— PSEUDOMOPIN^. 



Genus^ — Ischnoptera, Burm. 



Ischnoptera brunneonigra (male). Female — Tepper, Trans. 

 Roy. Soc. S. Aust., 1895, p. 155. 



Head, with the vertex and frons, pale brown, terminal joints 

 of the palpi paler. Eyes black. Antennae brown, with the 

 distal half of each joint paler, giving the antenna an annulate 

 appearance ; this is most marked in the proximal 6 or 8 joints, 

 which are nitid, and not so densely ciliate as the distal joints. 

 Pronotum trapezoidal, exposing the vertex ; sides deflexed, 

 brown, shining, much darker laterally and posteriorly. 

 Tegmina extending beyond the apex of the abdomen, brown, 

 shining ; discoidal sectors 9, longitudinal, anterior one bifurcate ; 

 costals 18. Wings hyaline, anterior portion infumate, veins 

 brown ; the anterior radial vein bifurcate beyond the middle ; 

 the posterior radial vein simple ; ulnar vein with one incomplete 

 ramus towards the dividing vein, and four complete rami to 

 the margin of the wing ; first axillary vein tri-ramose ; apical 

 triangle inconspicuous. Abdominal tergites brown, shining, 

 darker laterally and posteriorly ; first and seventh tergites with 

 medial gland openings ; posterior margin of the sixth tergite 

 arcuate. Supra-anal lamina dark brown, shining, produced, 

 posterior margin prolonged into a rounded point. Sub-genital 

 lamina brown, shining, ample, extending beyond the supra- 

 anal lamina, somewhat asymmetrical, being fuller on the right 

 side ; furnished with two broad-based conical styles, placed 

 one medially and the other on the left side. Abdominal sternites 

 brown, shining, with the lateral margins much darker than the 

 disc. Legs pale brown, anterior femora on the anterior borders 

 with four large spines occupying the middle third, succeeded
