- Apical margin of fore wing ciliate over at least its posterior half. Gaster as long 



as or somewhat longer than head plus thorax, 2-25-2-7 times as long as broad, 

 not broader than the thorax. Head shaped much as in Dibrachys cavus (Text- 

 fig. 670), with temples only about one quarter as long as eyes and converging 

 strongly. Femora, and hind tibiae, usually more or less infuscate

I am unable to provide a key to the males of Tritneptis at present. 



Tritneptis lophyrorum (Ruschka) 

 Diglochis lophyrorum Ruschka, in Ruschka & Fulmek, 191 5 : 400-401, fig. 1, o* ?• 



Type material. Syntypes, Bohemia, Humprecht, 1911, bred from cocoon of 

 Lophyrus pint L., presumably in Naturhistorisches Museum, Vienna. 



I have not seen the types of lophyrorum, but Ruschka's description accords very 

 well with the specimens I have so named. Gahan (1938 : 215) placed lophyrorum 

 in synonymy with Tritneptis klugii (Ratzeburg) but he had not seen the types of 

 either species. There seems to be no doubt that Gahan was right in his interpreta- 

 tion of klugii, but I cannot follow his opinion regarding the identity of lophyrorum ; 

 the respective original descriptions suggest to me that two different species are 

 involved. 



Ruschka's description of the female of lophyrorum (1915 : 400-401) states 

 " Hinterleib sehr Kurz, oval, Bohrer etwas vorstehend . . . Kopf und Thorax dunkel 

 erzfarben . . . Hinterleib an der Basis braun durchscheinend, hinten pechbraun ". 



On the other hand, Ratzeburg's description of the female of klugii (1844a : 198) 

 includes the following statements: " Hinterleib langer, als Rumpf, eiformig, 

 stachelspitzig-kurzzugespitzt . . . Rumpf und Kopf stahlblau (letzterer offers 

 grunlich), Hinterleib metallisch braunlich." Gahan (1938 : 216) supplements 

 Ratzeburg's description by saying that the abdomen of female klugii is " as long as 

 the head and thorax or longer, elongate ovate in outline, and fully twice as long as 

 broad. The venation, shape of the abdomen, and most of the other characters 

 agree very closely with those of the genus Dibrachys Foerster, but the absence of 

 any semblance of an occipital carina at once excludes the species from that genus ". 



Tritneptis klugii (Ratzeburg), as interpreted here following Gahan, has indeed 

 much the same facies as Dibrachys cavus (Walker), having a dark bluish head and 

 thorax and an elongate, immaculate gaster. Incidently Ratzeburg (1844a : 198) 

 compared klugii with his Pteromalus tenuis, which is now considered to be the male 

 of cavus. 



On the other hand, Tritneptis lophyrorum (Ruschka) has more of the general 

 facies of a Diglochis as regards the head and the short, oval to subcircular gaster, the 

 latter also paler at its base. 



It may also be pointed out that Ratzeburg later (1852) placed klugii in his 

 section II of Pteromalus, which section is characterized (p. 236) as having the 

 postmarginal vein 1-5-2 times as long as the stigmal vein ("Der Costalnerv ist 

 i|— 2 Mai so lang, als der Radialnerv "). Females which I presume to be klugii
