Apatania muliebris, McLach., in Lanarkshire. — During the last ten years I 

 have had occasion during the month of May to pay several flying visits to a locality 

 in South Lanarkshire situated at the foot of a hill called Tinto (about 2100 feet). 

 Almost every time I have taken a single specimen of an Apatania at a clear rill 

 running alongside the road, such a little perennial watercourse as one frequently finds 

 in districts whore hill-side springs are numerous. The examples taken were always 

 ? , and as Apatania Wallengreni has been recoi'ded from streamlets in the Kil- 

 patrick Hills, I considered that my captures were that species, and I did not 

 critically examine them. A good many $ examples of Apatania (unaccompanied 

 by (?) recently came into my hands from Arctic Norway, where they were collected 

 by Herr Strand. The genus is one in which the species much resemble each other 

 in general facies, and while the $ genitalia have strong distinctive characters, in 

 the $ the abdomen has a tendency to shrivel, causing the species in many cases to 

 be practically indeterminable from dried examples in that sex. To see if a moro 

 intimate knowledge of the true structure of the apical abdominal segments could be 

 obtained, I prepared a number of bodies as microscopical objects, and as these dis- 

 closed some rather remarkable points of internal structure, I was led to prepare in 

 the same way females of all available species of the genus, including the Tinto 

 insect. A glance at the preparation of the last named showed something absolutely 

 different from A. Wallengreni, and a beautiful preparation from an example of A. 

 muliebris from the original Arundel locality (kindly provided specially by Mr. 

 McLachlan) unmistakably proves that the South Lanarkshire insect is also muliebris. 

 On the internal structure already alluded to, muliebris is more widely separated 

 from the other members of the genus known to me than these are from one another ; 

 but on the subject I shall say more at another time. The precise locality in South 

 Lanark will probably in these days of improvement be ere long improved out of 

 sight, but in such a water producing district a careful search will no doubt discover 

 other localities for the Apatania.— Kenneth J. Morton, 13, Blackford Road,

Notes on Rhogas circumscriptus, Nees. — In July, on " Cress," I found, head 

 downwards, in a perpendicular position the dead larva of a Noclua, most probably 

 one of the Caradrinre, which at first sight appeared to be simply resting from its 

 feeding, but a curious opaqueness of the tegument caused me to examine it more 

 carefully; I then discovered that the skin, which had a very distinct lateral border, 

 was inflated to its fullest capacity and that it was fastened to the leaf by some 

 viscous substance so firmly that it required considerable force on my part to tear it 

 away, and even then it was only the leaf that was rent and not the viscous matter. 

 The larva was fixed only at the under-side of the head and second segment, the two 

 hind pairs of legs and all the prolegs being distinctly visible and in no way attached 

 to the leaf, but the first pair of legs were concealed in the solidified adherent 

 substance. The anterior segments were much contracted and transversely wrinkled, 

 and the thirteenth was shrivelled up with the anal prolegs, consisting of a mere 

 membrane protruded horizontally. Soon afterwards (July 24th) a Braconid which 

 my friend Mr. Claude Morley, of Ipswich, informs ine is referable to llhogas 

 (Aleiodes) circumscriptus, Nees, emerged through a large irregularly circular hole 

 gnawed by the imago through the dorsum of the eleventh and twelfth segments.
