288 THE entomologist's record. 



The typical abdominal segments have also five subsegments, but 

 they are not all well-marked. The division between the 1st and 2nd 

 is marked by a pair of green depressions, placed transversely, just behind 

 the two tubercles i. Tubercle i is on the 1st subsegment, tubercle iii, the 

 spiracle, and tubercle v on the 2nd subsegment, while ii and iv are on the 

 3rd subsegment. Above the proleg is tubercle vi (or vii). On the 8th 

 abdominal segment, as in the fifth instar, the trapezoidals form almost 

 a square, and on the 9th a reversed trapezoid. The anal flap is 

 greenish, and has two tubercles in the centre, and a row of six on its 

 border. There are fovir tubercles on the anal claspers. The primary 

 tubercles have long white hairs in this instar, and the secondary small 

 tubercles are mostly brown, except on the dark areas of the larva, where 

 they are still black, as on the dorsal stripe, etc. The white points are 

 still more numerous and conspicuous than before, some being 0-07mm. 

 wide at the base, and 0"lmm. high. Perhapis the most conspicuous of 

 these are situated as a pair in front of tubercle i, and three, forming a 

 triangle, on the inner side of tubercle ii. These points are very wide at 

 the base, and taper rapidly to a fine point. 



Myrmecophilous notes for 1906. 



By H. St. J. K. DONISTHOEPE, F.Z.S., F.E.S. 



Having had a very successful year with ants' nest species, the 

 following notes deal with the more interesting captures, and record new 

 localities for others. 



CoLEOPTERA. — Thiasopkila inqailina, Mark. — I have, this year, taken 

 a dozen of this very rare species, with Lasitis fidiginosiis, at Wellington 

 College. I have only found it in the very heart of the nests, and from 

 the deepest packing ; Dr. Joy tells me this was always his experience. 

 I kept some specimens alive to experiment with, and they were found 

 to protect themselves in the usual way, which I have demonstrated 

 (Ent. Record, 1901, p. 319, and 1903, p. 11) other myrmecophilous 

 "staphs" use, when attacked, against the ants. Tbey were tested with 

 Formica rnfa, F. c.mecta, and their own hosts. When approached by 

 an ant they stood quite still, and raised the tail high in the air ; the 

 ants would not touch them, and when forced to seize them, dropped 

 them again at once. 



Ateiiieles paradoxus, Gr., was taken by Mr. Keys and myself at 

 Whitsand Bay, with Formica ru/ibarbis var. fusco-rujibarhis, in May. 

 This is the only Formica species it is found with. We did not take it 

 again in September, when we were searching the nests of this ant ; but 

 no doubt it was in the Myrmica nests, as Atemeles appears to go from 

 Myrmica to Formica nests about February, when the larvae are bred, 

 and in summer or autumn the newly-hatched beetles go from Formica 

 to Myrmica nests to pass the winter. This has always been my 

 experience. 



Lomechusa strnmosa, F., was rediscovered by me in this country, 

 on May 25th, at Woking, with Formica samjuinea [Ent. Record, 1906, 

 p. 159), more specimens were taken on the 29th, and again in Septem- 

 ber. This was, no doubt, the most sensational capture we have had 

 with coleoptera in this country for years, moreover, the lifehistory of 

 the beetle is of exceptional interest. It has been thoroughly worked 

 out and described by Father Wasmann in many of his writings. The
