]68 REPORT ON ZOOLOGY, MDCCCXLII1. 



Tlie name Hemerobim has been again used by the author for Chrysopa of 

 later writers. Lastly, such species of Corydali*, the males of which have 

 simple mandibles, are constituted into a separate genus, Neuromus. 



Schneider, iu his ' Inaugural Dissertation' delivered at Breslau, has given 

 a very good monograph on Rapliidia. Seven species have been observed, 

 and are figured with their earlier states : (1) R. ophiopsis, Schumm. 

 (2) R. xanthostigma, Schumm., under which, however, two species are still 

 confounded ; they differ in the ocelli, and especially in the venation of the 

 wings. The true R. a-ctntlioxliyma has been figured by Schummel; the other, 

 very distinctly, iu this work. (3) R. ciffuns, a new species, related to the 

 former. (4) R. media, Burm. (5) R. major, Bunn. ; which, without hesi- 

 tation, I regard as R. megaceplialus, Leach. (6) R. notata, F. (7) R. c/v/.y- 

 sicorms, Schumm., for which the author institutes a special subgeuus, 

 Inocellia, distinguished, less by the deficiency of the ocelli, which are also 

 absent in some species of true Raphidite, than by the shortness of the 

 prothorax. 



Grube's excellent ' Beschreibung eiuer auffalleudeu, au Susswasserchwam- 

 men lebeudeu Larve' (Description of a remarkable larva inhabiting fresh- 

 water sponges), in these Archiv. (1843, i. Bel. s. 331, tab. x), has been 

 already mentioned in the last year's Report, p. 235. 



PHRVGANIDES. Rambur (Hist. Nat. d. Ins. Neuropt.) has added several 

 new genera to tin's family : Oliffotricha, differing from Phryganea in the 

 nearly naked wings, including Phi: retic/data, and phaleenoides, L., and two 

 supposed new species ; Eiioicyla, oral organs as in Limnephila, the four pos- 

 terior tibias with only a single pair of spurs ; E. sylcatica, new species, 

 plentiful near Paris, in woods, in the autumn; Monocentra, the four posterior 

 tibiae with a single spur in the middle, the wings covered with minute 

 hairs and scales ; in other respects, particularly in the palpi and venation of 

 the wings, agreeing with Limnephilw ; M. lepidoptera, from Sardinia. The 

 four following genera belong to the group Sericostomidas, Steph., which 

 Rambur names Trichostomides : Poyo/iostoma (the name has been appropriated 

 to a coleopterous genus), with one pair of spurs on the middle tibia 1 , and 

 on the posterior tibiae, a single spur in the situation of the superior pair; 

 P. vernum, common in the spring, on the Seine, at Paris ; Dasystoma, with a 

 single pair of spurs on all four posterior tibia?., antennae denticulated ; D. pul- 

 cJiell/im, from Spain ; Lasiostoma, coinciding probably with Silo, Curt. ; 

 Lepidostoma, with Goera, Hoffgg. ; lastly, Setodes, differing from Hystacida 

 iu the inferior wings not being plicated, as, for instance, Phr. pitnctata, F. 

 It is as curious that the author's new genera should so little coincide with 

 those of Stephens and Curtis, as that their works, especially the sixth volume 

 of Stephens's 'Illustr. Brit. Ent. Maud.' which has been published ten years, 

 should have remained unknown to him, in Paris.
