tells us of Tr. gymnopterorum (L.) (N. B. called by bini Tv. hole- 

 sericeum (L.) (sic!)) 



Of the legs it is necessary to inention that, according to their 

 lengths the range is: 1, 2, 4, 3; that the hairs of the last pair 

 are in geveral longer, those of the first pair in general shorter; 

 that of all the legs the proximal joints bear in general longer 

 hairs than the distal joints; and that the distal ends of all the 

 joints of all the legs bear in general longer hairs than their proxi- 

 mal ends. — I don't observe any hairy caruncle (pulvillum, sco- 

 pula) on the legs. Trouessart asserts it is present. 



The mandibles (Pig. 46) have a very short blunt and rounded 

 fixed finger (ra. d. f.) and a claw-like large movable one (ra. d. ra.). 

 They pinch between their bases the stigmata (s). 



The maxillae (ma:) are wholly fused together. Their palps are 

 inserted on the dorsal side (!) of the coalesced bases of the ma- 

 xillae (ra. p.). The triangle formed by the maxillae and the man- 

 dibles is distinctly demarcated from the rest of the body (along 

 the line a). Consequently there is a very pseudocapitulum or capi- 

 tulum, which is fiat and horizontal on its dorsal side. 



Immediately behind the capitnlum, behind the line a (Fig. 46), 

 the abdomen (or notogaster) stands perpendicularly (between the 

 lines a and b. Further the abdomen covers, like a prominent 

 forehead the capitulum, in some individuals partly (Fig. 43), in 

 others, especially females, even so far, that only the »claws" of 

 the palps are visible, when the animal is viewed from its dorsal side. 



In fig. 46, o signifies the base of the pedunculate eyes, which 

 are situated on the same level with the foremost, dark coloured, 

 well chitinized part of the crista, so that the pseudostigmata are 

 an a level behind the eyes. In fig. 46 p 1 signifies the implanta- 

 tion of the first pair of legs, which are consequently on a level 

 bef ore the eyes. 



Fig. 47 represents the greater part of the crista, with the two 

 pseudostigmata and the pseudostigmatic organs. 



On page XLIV of the Bulletin Eutomologique (Annales de la 

 Soc. Ent. de Fr., 1894) Prof. Trouessart mentions that he has
