trees,' decidedly scarce and difficult to obtain. I have seen four 

 of these, of the sex of which I am somewhat doubtful, but from the 

 small eyes they appear to be females. 



This pretty little insect (which seems to form the type of a new 

 genus on the characters mentioned) is somewhat deceptively similar 

 (at first sight) to Trichopsocus Dalii, McLach., in consequence of the 

 dark spots at the apices of the nervures on the otherwise colourless 

 wings. 



Explanation of figures- -'For these figures I am indebted to my friend the 

 Rev. A. E. Eaton, and give tlieir explanation ahnost in his own words. Fig. 1, 

 wings from under-side (in fluid) ; la, verrucosity (" liook " or " tooth ") of inner 

 cross vein of pterostigma, seen edgewise in front of the costa, two views of different 

 enlargement (dried). Fig. 2, part of head, with eye, maxillary palpus, and basal 

 portion of an antenna ; 2a, basal joints of an antenna, inner-side ; 2b, same, outer- 

 side (more enlarged). Fig. 3, ocelli (greatly enlarged). Fig. 4, extremity of 

 intermediate tarsus (greatly enlarged, and somewhat flattened, showing the empo-

NEUROPTERA AND TRICHOPTERA OBSERVED IN 



WiaXOWNSHIRE DURINQ JULY, 1899, INCLUDING TWO SPECIES 



OF HYDROPTILIDzE NEW TO THE BRITISH LIST. 



BY KENNETH J. MORTON, F.E.S. 



Any one looking over the lists of Scottish Trichoptcrn published 

 in the "Scottish Naturalist " in 1884-5, cannot fail to notice that the 

 records from the two great southern river systems are very meagre. 

 Those from Tweed are indeed a perfect blank ; and while those from 

 Solway are very much better, they obviously do little more than give 

 an outline of the Trichopterous fauna of the area, being in fact mainly 

 the results of the collecting of Mr. Robert Service, a keen ornithologist 

 and an excellent all-round naturalist, but who naturally did not a[)ply 

 himself to the Orders Neuroptera and Trichoptcra with the exclusive 

 attention of the specialist. 



The Tweed area (in which I have had the opportunity of doing a 

 little autumnal collecting quite recently) thus offered a virgin field ; 

 but when it came to carrying into effect a long-felt desire to do some 

 summer work in the southern parts of Scotland, my inclinations were 

 altogether in favour of the selection of one of the less-known regions 

 of the Solway area, where, with a southern latitude, a moderate ele-
