Thoughts on the Hymenoptera Trichogrammatidae etc. 75 



inust conclude that the Trichogrammatidae are more closely related, 

 to the Eulophidae. 



The Trichogrammatidae differ from all other chalcidoids, so far 

 as I can ascertain under present circumstances and so far as I can 

 reraember from experience in bearing but three tarsal joints in the legs 

 and lacking the strigil of the cephalic tibiae, the cephalic tibial spur 

 most often absent, when present very minute and straight, not long, 

 curved and forked at tip. These make up the sole characteristics 

 of the family. All members of the family bear the thoracic phragma 

 projecting well back into the abdomen which is always sessile. The 

 postmarginal vein is always absent, the parapsidal furrows always 

 complete, the axillae advanced into the base of the parapsides. 



6. The Kesemblances of Japania Girault and TJfens Girault- 



Happening upon species of these two genera I was at once Struck 

 by their likenesses and thus lead to compare them. At first they seemed 

 the same. Japania however, bears a shorter antennal funicle, its two 

 joints short, transverse; the ro.arginal and stigmal veins of the fore 

 wings are longer but not very much longer; the principle difference 

 between the two is greater than these, however, and lies in abdominal 

 peculiarities. The abdomen in Japania is long, slonder and conic- 

 ovate, the ovipositor very long, inserted at base and slightly projecting 

 beyond apex. In üfens the abdomen is short, obliquely truncate 

 behind, the ovipositor short, not inserted at base of abdomen but about 

 at the middle of its venter or at the apex of the proxim^al half. The 

 funicle joints in Ufens are subquadrate or only slightly wider than long, 

 the funicle as long or longer than the pedicel. Moreover, in Ufens, 

 the male differs from the fem^ale. 



7. Cephalic Tibial Spurs in the Trichogrammatidae' 



Cephalic tibial spurs have been detected in five recently described 

 Australian genera, Chaetostricha flavipes and Uscana; they have not 

 been detected in Oligosita, Tumidiclava, Aphelinoidea, Paratricho- 

 gramma (Australian), Ufens, Japania, Trichogramme, Neotrichogramma, 

 Brachistella, Ittys, Pterygogramma (Australian), Uscanoidea, Abbella 

 nor one undescribed Australian genus. Members of all these genera 

 have been examined but the possibilities have not been exhausted 

 and the list may need correction. 



8. Another Figure of Trichogrammatoidea nana (Zehntner). 



In Wilhelm Krügers Das Zuckerrohr und seine Kultur. Magde- 

 burg und Wien, 1899, p. 366, fig. 49, 1—3, there is given „Nach 

 Zehntner" a colored figure of the female and dra wings of the male 

 and female antenna, all enlarged. It is noticed that the female antenna 

 is shown with two ring- joints, in this respect not agreeing with the re- 

 drawn figure (from the original) given by myself in the Transactions 

 American Entom.ological Society, Philadelphia, 1911, XXXVII,
