six specimens exhibited, although apparently all found at the 

 same time and place and supposed by Burchell to be of one 

 species, actually consisted of no less than five species of three 

 genei'a. Dissections were also shown illustrating the means 

 by which the sound is produced in the Passalidte. 



Mr. C. 0. Waterhouse exhibited five drawings illustrating 

 the development of the front-wing in the pupa of the Tusser 

 Silk Moth, showing the relation of the tracheae to the veins. 

 These were prepai'ed for exhibition in the Natural History 

 Museum, and were made from the specimens exhibited at the 

 Society's meeting in February 1896. {See Proc. Ent. Soc. 

 1896, p. ii.) 



He also exhibited some coffee berries from Uganda injured 

 by a small beetle belonging to the Scolytidse. The beetles 

 laid their eggs in the berries when young and green. The 

 mature berries were often found with little of the inside left. 



Mr. Waterhouse further exhibited two Coleopterous larv?e 

 from the Burchell Collection from Brazil, submitted to him 

 for determination by Prof. Poulton. One was a Heteromerous 

 larva (numbered 1154) two inches long, much resembling the 

 larva of Helojis. The more interesting one (numbered 1330) 

 was noted by Burchell to be luminous. It was one inch 

 in length, subcylindrical, and appeared to be the larva of 

 an Elaterid, but the prothorax was unusually large, and the 

 head retracted beneath ; the mouth parts, although not those 

 of a typical Elater, conformed more to that type than to any 

 other with which he was acquainted. 



In connection with Mr. Waterhouse's exhibits the 

 President contributed the following notes: — "1154" is 

 attached not only to the larva but also to the Anthribid 

 Ptychoderes elongatus, Germ. The note is as follows : — " 1154. 

 Cut out of dead wood but not quite perfected. The long 

 cylindric larva of this number was said to be cut from the 

 same piece of wood and therefore may be the same insect." 

 Dated Dec, 17, 1826. Locality, Cubatao; between the 

 "Middle Part" (Dec. 16) and the "Upper Part of the 

 ascent" (Dec. 22) of "the great range of mountains," the 

 Sierra da Cubatao.
