" Trochilium Gallivorum. — Measures 8 lines in the expanse of the fore wings and 

 5 lines in the length of the body. It is of a blue-black colour, with two slender, pale 

 yellow diverging lines on the sides of the thorax above, and with the edges of the tail 

 also pale yellow; the wings are transparent, except the dark fore margin, a curved bar 

 across the middle, and a pale brown apical border} the legs are yellow, with a dark 

 ring round the tibiae near the tips." 



" Cynips palliceps. — Of a black colour, with the head and front and under parts of 

 the thorax pale yellow; the males are distinguished by the large size of their heads. 

 Length rather less than 2 lines." 



Economy of Evania. 



Mr. Westwood said a connection between Blatta and Evania had often been no- 

 ticed without the nature of it having been understood: he had recently had an oppor- 

 tunity of investigating the subject, a correspondent having sent him some egg-capsules 

 of an exotic species of Blatta imported with Orchidaceous plants, and he had found 

 Evania appendigaster, in the several states of larva, pupa and imago, within these 

 capsules. 



Captures by Mr. Curtis. 



Mr. Curtis said that when on a visit recently to Mr. Dale, at Glanvilles Wootton, 

 he had taken the following insects: — Myrmica graminicola, $ only; Ephyra orbicu- 

 laria, June 10th, a fine $ ; Crambus uliginosus, June 15th to July 1st; Limnobia 

 6-guttata, Hal., June 15th to July 1st; Acentropus Garnorisii, June 15th to July 1st. 

 Concerning the latter insect he should make a communication at a future Meeting. 

 At Clifton he saw Mr. Walcott's beautiful collection of bees, from which he exhibited 

 two captured with the wings in a rudimentary state. At Mr. Vaughan's, at Bristol, 

 he noticed the method of capturing small moths in glass tubes, invented by Mr. Brown, 

 of Burton-on-Trent, and exhibited a sample. 



Singular Beetle found in South- American Ants' Nests. 



Mr. Westwood read a notice, accompanied by drawings of dissections, of a very 

 curious beetle found by Mr. Bates in ants' nests, in the Valley of the Amazon, pos- 

 sessing the characters of several families, and so anomalous that it was very difficult 

 to indicate its nearest relationship ; and he further remarked that it was very singular 

 that all the many Coleopterous insects found in ants' nests should have some peculi- 

 arity of form or structure. He described the present species under the name of 

 Gnostis Formicicola. 



New British Hemerobii, fyc. 



Mr. Curtis read a paper on two new British species of Hemerobius, with remarks 

 upon the synonymy of Coniopteryx, &c. — J. W. D.
