Dr. G: Dimmock showed samples of the 

 different grades of Central American cochin- 

 eal, carminic acid and some of its salts. 



Dr. G : Dimmock showed specimens of 

 several curious insects. Among them was 

 a Culex with a parasitic nematod (.? Gor- 

 ditcs) dissected from its abdomen. The spec- 

 imen was taken near Leipzig, Germany. 

 The parasite was very large, relatively to the 

 size of the Culex. No parasitic worms had 

 been previously' recorded from Culex, except 

 Filaria sanguinis-hominis.. altho Mertnis had 

 been found in Stmulium reptans, in Tattypus 

 nebulosiis s.nd in a species of Chironomus, and 

 Gordius had been taken from Chiro7iomus 

 plumosus.

 pods and arachnids." {Psyche, Jan. -Mar.

Dr. G: Dimmock showed specimens of the 

 larva, pupa, and imago of Tinea cloacella. 

 The larvae feed in Polyporus betulinus. 



Dr. G : Dimmock described a process of 

 preparing the larvae of insects by boiling 

 them in strong alcohol, and exhibited speci- 

 mens prepared in this way. Among the 

 specimens shown were lepidopterous larvae 

 ^xoh'iCoXy pyralidae, which were taken in Oc- 

 tober 18S5 from the larger stalks of Zizania 

 aquatica (Indian rice) growing in a small 

 stream in Arlington, Mass, near the boun- 

 dary line between that town and Cambridge. 

 The larvae eat" out the scanty pith partitions 

 and the inner portions of the larger stalks. 

 The larvae are from two to three centimetres 

 long, dirty whii.e in ground color, with longi- 

 tudinal brownish stripes upon the upper side, 

 and a dark brown head and pronotum. They 

 have eight pairs of legs ; a pair each on seg- 

 ments 1-3, 6-9, and 12. 



Abstract of Secretary's Report, 8 yan.'86. 

 By G : Dimmock. 



The present meeting of the club is the 

 ii6th. In the last annual report of the sec- 

 retary the number of active members was 

 reported to be twenty-seven ; of associate 

 members, forty-nine. During 18S5 no new 

 members have been elected, and three per- 

 sons have withdrawn, leaving twenty-four 

 active members. One associate member, 

 Mr. H. K. Morrison, died during the year, 

 leaving forty-eight associate members. . . 



The officers of the club have continued 

 over from 18S4, because of alack of a quorum 

 at the meetings.
