ENTOMOLOGY HYMENOPTEKA. 361 



Dahlbohm has published a second part of his ' Hymeuoptera Europiea,' 

 but as a third part has appeared since (in 18-45), completing the first section 

 of the work (the genus Sphex in the Liunsean acceptation), and containing 

 the supplement to the first part, I reserve the review of the work for the 

 next year's Keport. 



[A. de Pohorsky Jorauko (Bull. Mosc. 149, pi. 6) has examined very 

 particularly the structure of the frog (pulvillus) between the claws in this 

 order. He finds it to be much more complicatqd than in. Diptera, and con- 

 firms the opinion of Leach that it acts as a sucker. The description is 

 taken from Apis mellifica, but he finds the structure nearly alike in other 

 Apidae, Vespidse, Teuthredinidae, Crabrouidae, Chalcidas, Cyniphidse, and 

 Scoliadae.j 



Herrich Schiiffer has given copies of Curtis's figures of Hyrnenoptera 

 (some Pteromaliua, the rest Oxyura) in No. 184 of his continuation of 

 Panzer's Fauna. 



Siebold has given a list of the Tenthredinida?, Siricidas, and Cyniphidee 

 of Prussia, with an appendix to the Eossoria. (Preuss. Prov. Blatt, 121.) 



TENTHKEDINET^E. Hatzeburg (Eorstius. iii, 135; Eutom. Zeit. 148) 

 distinguishes the false caterpillar of the Cimbex that lives on the alder, 

 figured by Degeer, Erisch, aucl Roesel, as belonging to a peculiar species, 

 C. humboldti, the fly scarcely to be known from C. variabilis, the larva of 

 which feeds on the birch. A male reared from one of the larvae from the 

 alder has been compared with the specimens of C. variabilis in the Berlin 

 Museum ; and, though no specimen was found among these, agreeing per- 

 fectly with it, the distinguishing marks which the author gives are of such a 

 nature that the fly cannot be known with certainty by them ; being such as 

 either rest upon a " more" or " less," or else occur in some individuals of 

 C. variabilis, for example, the colour of the feelers, and the shade of a 

 reddish pile upon the abdomen. Further observations are necessary to esta- 

 blish the propriety of considering this as a distinct species, the more 

 so as the larva of C. variabilis is known to undergo considerable varia- 

 tions in colour. The author takes no notice of its occurring upon willows 

 also. 



Snellen von Volleuhofeu (Hoev. Tijdschr. x, 97, pi. 2) has described the 

 larva of C. lucorum, about which there has been much uncertainty until 

 now. It is light green with mealy white stripes, a dark green stripe down 

 the back, the head light green, with the crown orange or ochre brown. It 

 is found on the hawthorn. The pupa case is not open net, like that of C. 

 amerinae, but of a close texture, as in C. variabilis. An appendix to this 

 paper (ibid, xi, 157) gives the descriptions of the larvae of Tentkredo (Se- 

 landria) sericans, which lives on the ash, of Nematus virescens, Hart. Cladius 

 eucerus, Kl., wicinatus, Kl., and Nematus caruleocarpus, Hart.
