DESCRIPTION OF A NEW SPECIES OF PETLLOTOMA, WITH NOTE 

 ON NEMATUS CBASSICOHNIS, HTG. 



BY P. CAMEEON, T.E.S. 



Phtllotoma fumipennis, sp. n. 



Black, the abdomen above with aeneous tints ; the palpi, the labrum, clypeus, 

 the inner orbits of the eyes broadly, the tegulse, a thin line on the base of the pro- 

 notum, the trochanters, the knees broadly and the tibiae beneath, •white ; the tibi89 

 above fuscous-black ; the tarsi blackish, paler at the junction of the joints ; spurs 

 pale ; Tvings dark fuscous throughout ; antennae as long as the abdomen, densely 

 covered with pale pubescence, the apical joints brownish beneath ; 12-jointed, the 

 3rd joint nearly one-half longer than the 4th. Head densely pilose ; the pleurae 

 sparsely covered with longish white hair. Wings large, broad ; the third cubital 

 cellule dilated at the apex, as long as the first ; the recurrent nervures received before 

 the middle of the cellules. Length, 4"5 mm. 



In the table given in my Mon. Brit. Phyt. Hym., i, p. 284, the 

 above described species will come in as follows : — 

 5 (2) Antennae 12 — 13-jointed ; wings for the greater part smoky. 

 5a (5J) Wings uniformly fuscous ; tegulae and a narrow line on the pronotura 



white ; legs black, the trochanters, knees and tibiae beneath, white ; 



abdomen aeneous above fumipennis. 



5J (5a) Wings smoky, hyaline at the apex ; tegulae black, legs pale yellow, black at 



the base ; abdomen not aeneous above ochropoda. 



JP . fumipennis \^ Sb SYndMeT and broader species than ocTiropoda ; 

 the abdomen especially being broader and not much longer than the 

 head and thorax united ; the head between the antennge is broader, 

 flatter, and does not project so much, the antennae also being more 

 widely separated. 



Taken on alder by Mr. J. B. Bridgman at Norwich. 



Nematus ceassicoenis, Htg. 



This species has never clearly been recognised by recent writers 

 on the Tenthredinidoe. Thomson refers it doubtfully to his armaius ; 

 Andre, without any doubt at all ; Brischke and Zaddach do not men- 

 tion it ; but a (^ of the species I have described as N. ruficornis (Mon. 

 Brit. Phy. Hym., ii, 62) was returned to me by Zaddach bearing the 

 name of " crassicornis.'^ There is a species in this country which 

 agrees very well with Hartig's description of the latter, and more 

 particularly in having the clypeus " eingebuchtet," a point in which it 

 differs from all the other species of the ruficornis group, which have 

 the clypeus distinctly transverse in both sexes. As this forms an 

 addition to our lists of species, I give a description of it, leaving
