but differs by liaving the fourth vein bent at an angle instead of a curve, by the 

 outer cross vein being sinuous, and by the white fasciae on the abdomen being 

 narrower.

Frontalia narrow in the male ; central stripe piceous, and rather wider than 

 sides ; cheeks white, with dark reflections ; antennae with third joint between three 

 and four times longer than second ; arista with basal third tliickened ; facialia 

 ciliated rather more than half way up ; palpi black ; thorax black, grey in front, 

 where it is marked with four short stripes, almost confluent ; post-sutural outer 

 dorso-central bristles three in number ; abdomen dull grey, with an undulating 

 black mark on the second and third segments, forming three sub-triangular confluent 

 spots ; discal and marginal setae both present ; wings and scales rather nebulous, 

 the former with apical cross vein straight, and bent at the base in an obtuse angle ; 

 legs black, hind tibiae thickly, but not quite evenly, ciliated on their outer sides. 

 Kare ; in Mr. Dale's collection ; captured at Grlanvilles Wootton. Only the male 

 is known.

Frontal stripe black, equal in width to the sides of the frontalia, which ai'e 

 white, with dark reflections ; antennae with third joint only about three times the 

 length of the second ; arista thickened nearly to the middle ; palpi yellow or testa- 

 ceous; facial setae not extending higher than the middle of the face; thorax 

 cinereous, with four black stripes, which are often partly confluent ; post-sutural 

 outer dorso-central bristles three in number ; wings with apical cross vein nearly 

 straight, and bent at the base in a curve ; legs black. Rare ; in Mr. Dale's col-

PHILOPOTAMUS MONTANUS, DONOY., 



VAR. CHRYSOPTEEUS, MORTON, IN THE WEST OF ENGLAND^ 



WITH NOTES ON THE NEURATION. 



BY ROBERT McLACHLAN, F.R.S., &c. 



This variety was first described by Mr. Morton in the Ent. Mo. 

 Mag., vol. XX, p. 273 (1884), and subsequently by myself in the " First 

 Additional Supplement," p. 47, from examples taken by Mr. Morton 

 on a hill called " Tinto," in Clydesdale. My friend, Mr. E. Saunders, 

 has just given me three examples taken by him at Ilfracombe in May 

 of this year, which should, I think, be referred to this variety. In 

 colour, especially of the hind-wings, they are even brighter than the 

 typical Scotch examples (but these latter are now somewhat faded). 



In the original descriptions stress is laid on the fact that the 

 apical fork No. 4 has a footstalk. In one of the Ilfracombe examples 

 this fork has a very short footstalk, in the others it is sessile.
