were distinctly rai'e : later on, A.fulvicrus abounded along the coast, but they were 

 the two species most in evidence. The only Aculeate I was really anxious to 

 find was Ostnia xanthomelana, and of this one morning (May 3rd) I found a lovely 

 (? and ?, evidently just emerged, on the side of the footpath along the cUEEs 

 to Sandown. It is satisfactory to know that it still exists in the old locality from 

 whence Smith and C. W. Dale recorded it. I was also interested to find HaUctus 

 malachurus and its smaller form longulus burrowing freely in the hard pathways 

 along the cliffs. It is curious that this species should be so common in the Isle 

 of Wight and so rare on the mainland. — Edwakd Saundees, St. Ann's, Woking :

Pachylomma buccata, Breb., in the Isle of Wight. In Mr. Morley's interesting 

 notes on Bruconidie (aiitca p. 209), he devotes considerable attention to the above 

 species, of which he quotes very few British records. I have much pleasure in 

 noting it from the I. of Wight, where I met with it at St. Helens on August 27th. 

 I captured a ? hovering over a nest of Lasius niger, and striking at the ants in the 

 usual manner ; it was in company with the little fly, Phora formicarum, several of 

 which were also hovering over and striking at the ants. 



Mr N. Arnold records it in Russia, with Lasius ajffitils (Uorae Soc. Knt. Ross., 

 xvi, 1881, pp. 146-149). Mr. Morley has kindly identified my specimen. — Horace

This series promises to be an exceedingly useful one. The Trichoptera have 

 been dealt with by Herr Ulmer, who is well known as an indefatigable worker on 

 the metamorphoses of the Order, and who has also put our knowledge of exotic 

 forms into shape. His volume is quite a model little book, and is certain to prove 

 of the greatest use to students of the Trichoptera, not in Germany only, but in 

 Central Europe generally, including our own country, most of the British species 

 being of course included. Figures sufficiently serviceable are given of the genitalia 

 of all the species, many of these figures being taken from other good authors, a 

 general acknowledgment being made to that effect. Even to those who possess 

 McLachlan's great monograph the present work will be more or less indispensable, 

 on account of the newer things in classification, morphology, &c., which it presents. 

 It is now generally recognised that some of the great families retained by McLachlan 

 may conveniently, and on biological grounds may very properly, be subdivided, and 

 the following division and arrangement are adopted : —
