Fi... 1(17. Siljili>i iii.iritu, No. 769. Eight middle femur bearing a compounded 

 pair of extra legs. I', ventral surface of nearer extra leg. V, ventral surface of 

 the remoter extra lef,'. (In Rouen Mus.) 



770. Tenthredo SOlitaria (S, t \\lly): tibia of right middle leg divides 

 in peripheral third to form two branches, of which the anterior bears 

 i hr normal tarsus. Tlie posterior branch arises from the postero-ven 

 tral surface of the normal and bears a double tarsus consisting of the 

 posterior parts .,f a pair compounded in Position VP, almost exactly. 

 Tibial .spin's as in Fig. IDC). Tlie compound tarsus has only 4 joints, the 

 ">tli being apparently broken off. In Cambridge Univ. Mus., history 

 unknown. 



771. Telephorus rusticus ( Malacoderm ) : tibia of left middle leg dilated 

 and somewhat deformed in its peripheral portion. It presents two 

 apieal processes, the one anterior and the other posterior. The anterior 

 of these bears a normal, backwanlly directed tarsus, but the posterior 

 process bears t \\ o tarsi by separate articulations. The anterior of these 

 two tarsi is directed t'or\\ards to t'ace the tarsus of the other apex, but 

 the posterior tarsus is backwardly directed. [From its attitude it is 

 dear that the middle of these tarsi is a structure complementary to one 

 of the others, but there is no evidence to shew whether it is a pair to 

 t lie anterior or to the posterior. Posit ion either VPP, or DAA, pro- 

 bably the former.] K ICAAT/, 1>* <it. ent, /?/., 1SSQ, p. 344, tig. 33.
