Dr. Perkins also exhibited a species of Eupelrmis, remarking 

 that while the pronotum in the females of the Gonatopus and 

 its allies is freely movable, a most unusual condition in 

 Hymenoptera, the thorax of the Eupelminse is still more 

 remarkable, the suture between the mesonotum and scutellum 

 allowing of movement. Thus while the thorax behind the 

 posterior margin of the mesonotum is in one position at about 

 right angles to the mesonotum itself, it can at the will of the 

 insect be so straightened out that the mesonotum and parts 

 behind it are in the same horizontal plane. 



Mr. Kotinsky then read a note on "Hawaiian species of 

 Pseudococcus allied to citri." The author was certain that 

 the Pseudococcus on pineapple, sisal, and sour-sop was distinct 

 from P. citri but had not as yet discovered taxonomic characters 

 to differentiate them.

The twenty-seventh regular meeting was held in the Library 

 of the Board of Agriculture and Porestry, Mr. Giffard in the 

 chair. 



NOTES AND EXHIBITION OF SPECIMENS. 



Dr. Cobb exhibited a linen tester, the lower lens of which 

 was graduated in two directions to -I and ^ mm. which he 

 thought should facilitate the counting of punctures and other 

 structures upon a given area of an insect. He also exhibited 

 an ordinary pocket lens the cover of which was so perforated 

 that a dissecting pin penetrating the perforation might be 

 extended below to the focal distance and center of the lens, 

 thus serving as an aid in dissection. 



Mr. Terry exhibited specimens and read a note on what he 

 considered was accidental parasitism, viz. : Chalcis ohscurata 

 bred from a Tachinid pupa within that of a lepidopterous 

 pupa. Dr. Perkins stated that judging from the fact that the
