much smaller, is only 12 min. ; the males have the head much swollen behind the 

 eyes, it is less so in the female ; the transverse anal nervure is divided only just below 

 the middle, and all the coxte are black. 



2. I have only one male of this form, which I believe is the true tenmcorne, 

 The head is slightly swollen behind the eyes, and the transverse anal nervure is 

 divided well below the middle, as figured by Wesmael (Revue des Anora. de 

 Belgique). 



3. This appears to be the commoner form in Britain. The head is decidedly 

 narrower at the neck than against the eyes ; the transverse anal nervure is divided 

 ■below the middle, lower down than No. I, and higher up than No. 2. 



I can see no difference in the sculpture, it is possible that all are only 

 varieties of one species ; Holmgren says, " pleuris medio nitidis." I find the meso- 

 pleura is shining, punctate, with longitudinal rugae above. 



Mr. "W. H. B. Fletcher has bred two males of this same group 

 (having the antennae as long as or longer than the body) from mixed 

 larvae from sloe, taken in Abbotswood, Sussex, which differ from the 

 three species described, having the transverse anal nervure of the 

 hind-wing not divided ; from Irevicolle they differ in not having the 

 hind tarsi distinctly incrassated ; the flagellum is entirely dark ; and 

 the hind-legs are dark brown, v>dth tarsi partly pale. From vat^ifarsum 

 they differ in having the 1st joint of flagellum not more than one- 

 fourth longer than the 2nd, in varitarsum it is about twice as long ; 

 the sculpture of the mesonotum is much finer, and it is much more 

 distinctly trilobed ; they diifer from Jlavitarsum, Brischke, in the 

 colour of the legs and antennae, and in the sculpture of the thorax, 

 which Brischke says is coarsely and densely punctured ; below I give a 

 description : — 



Anomalok nigeipes, n. sp. 



AnienncR corporis longitudine, ales nervo transversa anali non fracto pedihus 

 posticis maxima exparte nigro-fuscis. 



Head not narrow behind the eyes ; antenn£e as long as the body, first joint of 

 flagellum not more than one-fourth longer than the second ; head with very fine 

 scattered punctures, finely rugose above the antennae, and in the neighbourhood of 

 the ocelli. Thorax somewhat shining, finely punctate, distinctly trilobed ; scutellum 

 somewhat depressed ; metathorax rather finely reticulate ; abdomen and legs 

 slender, hind tarsi slightly thickened. 



Black; face, mandibles, cheeks, a spot on vertical orbits, and scape beneath, 

 yellow ; antennae black. Abdomen red, the back of all the segments black, the 

 seventh entirely so. Front and middle legs yellowish-red, coxse and trochanters 

 yellow; hind-legs nigro-fuscous, apex of coxse reddish, extreme base of femora 

 reddish, middle of tibiae rufo-fuscous, apex of first tarsal joint and remaining joints 

 reddish.
