THE BRITISH PSYCHIDES. 155 



antennte. There is a circle still higher than the first two, that is, or 

 represents a fifth, but it wants the definite dark margin of the others. 

 The jaws have a smooth, sharp, chisel, cutting edge and no teeth or 

 serrations. The spiracles are brown, the first and last are nearly twice 

 as large as the others. The hairs are longer posteriori}' on the 9th 

 abdominal segment, iii is short, but i and ii are nearly 0-1 mm. long. 

 The 10th abdominal segment has a large anal plate on which are 

 hairs 0-15mm. long. These look like i and ii, and iv along the 

 posterior margin of the plate, which is itself 0"2mm. across. There 

 are several hairs behind this, but no definite tails as are common in 

 Satyrid larvte. The true legs are ochreous. Associated with each 

 proleg is a hair of ordinary type, i.e., without serrations and nearly 

 straight, and about 0-07mm. long. The prolegs each possess six 

 equal crochets about 0-05mm. long. The claspers have ten similar 

 crochets each. 



These two larvje died about the middle of October, I fancy because 

 I did not afford them suitable conditions for hibernation. 



Description of Plates. 



Plate X. — Fig. 5. — Larva half grown in first insfcar, or a little older, photographed 

 by Mr. Tonge, x 10. Sluggish as the larv;? are, Mr. Tonge found 

 them very bad sitters, as the exposure to a good light at once led 

 them to seek shade. The point of view brings the bi-oad lateral 

 subspiraeular band a little above the middle of the figure, and 

 brings the legs well into view. The subsegmentation is very distinct, 

 but the stripes on the upper part of the larva do not appear.

The British Psychides. 



By Eev. C. R. N. BUEROWS, F.E.S. 



The beginning of July brings near the conclusion of the Psychid' 

 season of 1917, and I am called upon to give an account of my failures 

 and successes. I have worked hard and carefully, anxious to learn all 

 I could. I have been rather disappointed at the small response which 

 my appeal for material has met with ; but considering the state of the 

 world, and perhaps also in a measure the unpopularity of this group of 

 Lepidoptera, I have received doubtless as much encouragement as I 

 had a right to expect. But to those kind and capable observers who 

 have given me their assistance I offer my sincere thanks. 



Perhaps in arranging my notes it will be better to follow the order 

 observed in my preliminary paper, published in the Entomolofiut's 

 Ftecord for April last. But I must first of all thank Dr. Chapman for 

 his remarks upon that paper. I had noted in my list the correction of 

 the name opacella, H.S., to atra, L., but retained the former as more 

 familiar to British collectors, who are still I fancy a little bit upset by 

 frequent changes in nomenclature. It would appear also that I was 

 too modest. I should have stated that the whole of the material which 

 I can gather together will, all being well, be deposited in the National 

 Collection, with that which Dr. Chapman has generously placed at my 

 disposal.
