Heterogyna. 

 In this section no new species has occurred, but a nest of Formica 

 fusca race gagates has been found in the New Forest by Mr. G. 

 Arnold (Ent. Mo. Mag., xli, p. 211). This is worthy of special mention 

 as the title of this "race" to a place in our list rested on a single 

 specimen taken by the late F. Smith witliout note of locality. 



FOSSOEES. 



Pompilus {Wesmaelinius) sanrjuinolentus, F. (Ent. Mo. Mag., xxxvi, 



p. 206). 



This species sliould stand first in the genus so far as the British species 

 are concerned. 



As a subgenus it may be known by the elongate pronotum, as in the subgenus 

 {Aporus), from which it differs in having three submarginal cells in the anterior 

 wings ; the propodeum is truncate and concave posteriorly with its lateral angles pro- 

 duced and dentate. In the posterior wings the median and posterior veins are 

 united by a transverse nervure at a point some distance above the branch of the 

 former; this character will separate it from all the other sections of the genus. 



The male is entirely black, the female black with the pronotum and propodeum 

 red ; it should not be mistaken for any other species.

Pompihcs nir/errimus, Scop. 

 This name has been adopted generally as the appellative for our 

 P. 7i7.ger, and as Scopoli's description agrees well with it I think it 

 should be used. 



Pompilus approximatus, Smith (Ent. Mo. Mag., xxxvi, p. 51). 

 This close ally of Pompilus nlgerrimus should stand next to it in our list. It 

 may be known from that species in both sexes by the more or less hairy propodeum 

 (especially at the sides), by the subquadrate 3rd submarginal cell, the short 4th joint 

 of the posterior tarsi which in the S is only half the length of the 5th, and in the 

 9 is as broad at its apex as it is long, and by the bifid claws of the <? . The abdo- 

 men of the $ is narrower than in nigerrimus.

Salius jjropinquus, Lap. ? (Ent. Mo. Mag., xxxvii, p. 247). 

 Of this nearly black species two examples have been taken by Miss Chawner in 

 the New Forest in August. It may be known at once from any of our other 

 members of this genus which have an eye-like spot in the apical region of the fore-
