more interesting because the presence of only two submarginal 

 cells was, as Prof. Poulton had learned from the Rev. F. D. 

 Morice, characteristic of a subgenus of Ammophila, which, 

 however, did not include any British species. 



The President stated that, at Prof. Poulton's request, he 

 had recently examined the specimen from the Burchell col- 

 lection (No. 1330), which was shown that evening, and he 

 had no hesitation in saying that it was either a larva or female 

 of the group Phengodini, a group placed by some authors in 

 the Telephoridae and by others in the Lampyridae. The 

 specimen had been exhibited on a previous occasion by the 

 late Mr. C. 0. Waterhouse, who was somewhat doubtfully of 

 opinion that it was an Elaterid larva (see Proc. Ent. Soc. 

 1904, p. Ixxxiv). Many years ago an insect supposed to be 

 the larva of a Pywphorus was exhibited at a meeting of the 

 Society by the late Mr. Frederick Smith; and from the 

 description of its luminous properties given (Proc. Ent. Soc. 

 1869, p. xv) there can be no doubt that that also was the 

 female or larva of some species of Phengodini. The females 

 of this group are completely larviform, and have the same 

 short antennae, simple eyes, and short simple clawed legs that 

 are met with in the larvae. Both larvae and females may be 

 distinguished from Elaterid larvae by the fact that the tenth 

 abdominal segment is somewhat conical or tubular in form, 

 and projects beyond the ninth segment so as to be visible 

 from above. 



New Cetoniids from British India. — Mr. 0. E. Janson 

 exhibited the four new species of Cetoniidae of the genera 

 Clerota, Pseudochalcotkea, and Anatona, described in the paper 

 subsequently read, and made some remarks on their characters. 



Temperature at which Insect Life is destroyed. — 

 Mr. A. Bacot desired to call attention to a very valuable 

 paper in the Memoirs of the Department of Agriculture in 

 India (Nov. 1916, Vol. IV, No. 6) dealing with the insects 

 attacking stored wheat in the Punjab, and the methods of 

 combating them, by Barnes and Grove, and said : The authors 

 show that the germinating powers of wheat submitted to a 

 temperature of 70° C. for 24 hours were not noticeably im- 

 paired; as they found that heating to 100° C. generally
