and Anthomyiidae in the interior, but there was an apparent scarcity of 

 the Muscoidea in general. He did not see any specimens of the house- 

 fly until he returned to British Columbia. For the first time in all his 

 years' collecting he captured both sexes of a species of the Lonchopteri- 

 dae in numbers at the same time. He said both sexes of these flies are 

 rarely captured at the same time. 



LEPIDOPTERA. Mr. Williams exhibited some of the larger North 

 American Hcsperidae and drawings of their male genitalia, calling 

 attention to several species superficially very close, but which showed 

 remarkable differences in the characters of these organs. 



ORTHOPTERA. Mr. Rehn made a communication upon the West Indian 

 species of the blattid genus Plccoptcra, illustrating his remarks with a 

 series including all the species now known from those island?.. The 

 speaker discussed the taxonomic features of the species and their groups, 

 particularly those of the genitalia.

OBITUARY.

Two obituary notices of the late Dr. DAVID .SHARP lie before 

 us from The Entomologist for October, by W. J. Lucas, and 

 from The Entomologist's Monthly Magazine, for the same 

 month, by J. J. Walker. Each is accompanied by a (different) 

 portrait. One refers to him as of the "very front rank of zool- 

 ogists," the other as "one of the most distinguished Entomol- 

 ogists of our time." "Unquestionably," says one, "Dr. Sharp's 

 magnum opus is the treatise on 'Insects' forming the greater 

 part of two volumes [V, VT] of the 'Cambridge Natural His- 

 tory'," published in 1895 and 1899, "but it is safe to say that 

 no work of equal value on general Entomology has been pro- 

 duced in this country since Westwood's 'Introduction to the 

 Modern Classification of Insects' appeared more than half a 

 century previously." When the present writer had to select a 

 general work on insects as part of a necessarily small collection 

 of books to accompany him during a year in Costa Rica, his 

 choice fell upon this work of Sharp's. Although Dr. Sharp 

 was a specialist in Coleoptera, his wide sympathies and experi- 

 ence made it possible for him to deal more equally with the 

 various orders of insects than almost any other one man could 

 have done, and the two volumes if largely compilations from 

 the nature of the task' contain much new material throughout.
