British Braconidce, he knew of but two British specimens, one of the two was bred 

 from the above host, and the other from an uncertain one. Ratzeburg, in " Die 

 Ichn. Forst.," records these two Ichneumons bred from L. testudo, probably one of 

 the two is hyperparasitio. Brischke records having taken Sphinctus serotinus as late 

 as October 6th. — John B. Bmdgman, Norwich : September, 1889. 



Agriotypus major, Siebold. — "When writing my paper on Agriotypus armatus 

 (ante p. 339), I felt sure that, sooner or later, I would find agriotypized cases of 

 Odontocerum albicorne, Scop., mentioned by Siebold (Stett., Ent. Zeit., 1861, p. 60), 

 and I was happy to detect, last month, in the rich locality Hradek, amongst hun- 

 dreds of agriotypized cases of Silo nigricornis, one of the Odontocerum, bearing the 

 well known appendage. The appendage was comparatively short, 10 mm. long and 

 1 mm. in diameter, stiff and strong, arising from the left side of the mouth opening. 

 The inner cocoon was 10 mm. long, leaving a very large space in the hinder part of 

 the case, in which were the remains of the devoured larva. The cocoon enclosed a 

 fully developed Agriotypus ^ • Siebold says he could find no differences between 

 the nymph of A. armatus and major, except in size. The same is true with respect 

 to the imago. I have measured examples from Silo in comparison with that from 

 Odontocerum, and found the length of body of the former to vary from 5'62 to 6'28 

 mm., and the length of the fore-wings from 4 to 4 - 43 mm. The length of A. major 

 (from Odontocerum) was 9 mm., and the length of fore-wings 6 mm. It agrees in 

 respect of size with the typical examples of A. armatus described by Curtis, but is 

 nearly twice the size of those ordinarily found at Hradek. The number of joints in 

 the antemite appears to be greater in the larger form. 



As in September of this year I found many agriotypized cases of Silo containing 

 not only nymphs, but also developed images of the parasite (and occasionally sub- 

 nymphs), it is therefore possible that it is on the wing also in late autumn ; but, 

 owing to the unfavourable weather, I could not find it. — Franz Klapalek, Prague : 

 October 2nd, 1889. 



Rare Aculeate Hymenoptera in 1889. — I have been devoting, throughout the 

 present year, such time as I could spare from engagements of a very different kind, 

 to collecting specimens of the Aculeate Hymenoptera, principally in the neighbour- 

 hood of Rugby, but also in other localities, in which, from time to time, I have 

 happened to be paying visits. With the proverbial luck of beginners, I have made 

 some captures which Mr. E. Saunders (after most kindly examining them all, and 

 verifying or correcting my attempted identifications) considers worthy of record j 

 and I send the following notes at his suggestion. 



Halictus atricornis. — Of this species (known hitherto, as far as I have been able 

 to learn, only by specimens taken long ago in Cheshire by the late Mr. B. Cooke, 

 and a single $ at Wotton, Gloucester, by Mr. R. C. L. Perkins in 1887, Ent. Mo. 

 Mag., xxiv, p. 91) I have taken both sexes (the males in considerable numbers) in 

 several places within a mile or so of Rugby. And, strange to say, happening in 

 August to visit the village of Whalley, in Lancashire, I took both sexes there also 

 in a sandpit. In Rugby, on May 21st and 22nd, I found atricornis $ entering and 

 issuing from burrows in the side of a ditch by the high road, and (apparently infesting 

 these burrows) I caught on both days females of Nomada Fabriciana. At or close 

 to the same spot I obtained also one female of Sphecodes ferruginatus.
