Genus SCELOSTENOPTERINA Hendel 



Scelostenopterina Hendel, Abhand. k. k. Zool.-Bot. Gesellsch., Wien, vol. 8, 

 p. 86, 1914. 



This genus is very similar to Plagiostenopterina Handel, and was 

 distinguished therefrom by its author by the thickened, spindle- 

 shaped femora. He did also mention that the thorax was narrowed 

 in front, but there is no distinction between the thorax and that of 

 typical Plagiostenopterinae before me, and I infer that the poor 

 condition of his single example of his genotype was responsible for 

 his assumption that the shape was different. I have very carefully 

 examined a number of specimens of the genotype in good condition 

 in the United States National Museum collection and find that in 

 most characters it agrees well with Plagiostenopterina^ having the 

 hind coxae haired at apices above, the humeral and mesopleural 

 bristles present, a well developed occipital bristle, four verticals, the 

 aristae short haired basally, and the wing venation almost as in 

 aenea Wiedemann. It differs, however, in having the femora all 

 thickened, the fore pair in the male with a short wart-like protuber- 

 ance near apex on the posteroventral surface, the face bare, and the 

 lateral portions of the postnotum with even more noticeable erect 

 fine hairs than in typical species of that genus. 



SCELOSTENOPTERINA FEMORATA Hendel 



Scelostenopterina femorata Hendel, Abhand. k. k. Zool.-Bot. Gesellsch., 

 Wien, vol. 8, p. 86, 1914. 



Very similar in general color and habitus to Plagiostenopterina 

 aenea Wiedemann, the wings hyaline with a narrow costal stripe, 

 and a central one extending from base to the inner cross vein, 

 fuscous, as in that species. 



The abdomen in the male has rather dense erect fine pale hairs on 

 the tergites, and the first visible tergite has from two to four long 

 black bristles in a vertical series on each side. The color of the legs 

 is rather variable, the fore and mid pairs sometimes being largely or 

 entirely fulvous yellow and sometimes dark brown. 



Locality, Mount Banahao, P. I. (C. F. Baker) . 



This is evidently some of the same material as was recorded by 

 Bezzi in 1917.i 



It is to be noted that the postnotal hairs in this species are on the 

 upper anterior triangular portion, not on the central posterior por- 

 tion as in aenea Wiedemann.
