from a '" puff-ball " (Lycoperdon gemmatum) taken at Barton 

 Mills, Suffolk, on September 9, I '.'17. together with a specimen 

 ($) of Caenocara bovistae, Hoff., swept at Battle, Sussex, on 

 August 2, 1902, the only species of this genus known to occur 

 in Britain heretofore. 



Also specimens of Cryptophagus tyvendali, Ganglb., which 

 tie bad found in large numbers in a nest of Vespa germanica 

 in a tree in Richmond Park on November 20, 1917; a species 

 of w Inch only two specimens had been taken in Britain before, 

 by Mr. Champion in July 1907, in a hollow in an old beech 

 tree in the New Forest. Mr. Donisthorpe made some remarks 

 on the habits, distribution, etc., of these exhibits. 



II kmipterous Ova. — Mr. E. A. Butler exhibited ova of 

 the following species of Hemiptera : — 



Two species of Pentatomidae, Piezodorus lituratus, Fabr., 

 and Pentatoma rufipes, L. ; emergence from these is effected 

 by lifting a lid from the anterior end of the egg; according 

 to Fabre the embryo is aided in doing this by an apparatus 

 consisting of a thin membrane strengthened by a triradiate 

 chitinous framework, which could be seen in the group from 

 Pentatoma. Chorosoma schillingi, Schml., a Coreid bug, emerg- 

 ence from which is effected also by lifting a lid. but without 

 the accessory apparatus. Two species of Berytus, in which the 

 ovum is elongate and longitudinally sulcate, and emergence is 

 effected by the longitudinal fission of the egg at the anterior 

 end. Three Reduviidae, Coranus subapterus, L., Nobis major, 

 Costa, and Nobis rugosus, L. The two species of Nobis have 

 the shape of a short test-tube bent at the open end and with 

 the mouth placed obliquely. A Capsid bug, Miris laevigatus, 

 to which were added the five cast skins representing the live 

 larval instars of the individual produced from the single 

 ovum exhibited; and lastly, the ova, of three water hugs, 

 Naucoris cimicoides, L., Notonecta glauca, L.. and Nepa 

 cinerea, L. 



Two Species of Catagramma, and a new Dynamine. 

 Mi'. Kaye exhibited from Mr. Joicey's collection series of the 

 two Catagramma species pastazza and excelsior with races and 

 forms of each pointing out that the two groups of insects 

 were at once separable by the differenl tips to the antennae.
