trouble or weakness about the heart against taking any part in the 
application of carbon bisulphide. 
In view of the increasing use of CS, as an insecticide and the scat- 
tered condition of such observations as have been published in regard 
to it, the writer respectfully suggests the desirability of a more com- 
prehensive report than has yet been made, published in some such 
form as to be readily available to all those desiring practical informa- 
tion upon this subject. 
GENERAL NOTES. 
ICHNEUMONID PARASITES OF THE SUGAR-CANE BORERS IN THE ISLAND 
OF REUNION. 
Under this title M. Edmond Bordage, director of the Museum of 
Natural History of Reunion, has published a brief account of Ophion 
mauriti Saussure and of OC. antankarus Saussure, which are parasitic 
in Reunion on the larve of Diatrwa striatalis and Sesamia albiciliata, 
two destructive sugar-cane borers of that island and of Mauritius. He 
thinks that they are responsible for the marked reduction in the num- 
bers of the borers. 
The accompanying figures are from drawings by M. Bordage, and 
illustrate the wing venation of O. antankarus.

Fic. 29.—Wings of Ophion antankarus—I, upper wing; II, lower wing. The large cell (ed) of the upper 
wing has three spots of reddish or yellowish color, which are given in detail much enlarged in 
Fig. III; they take the form of a crescent, 2 mere speck, and a triangle. (With O. mauritii th >re 
is found in the interior of the large cell (ed) only one spot which is formed like a triangle.) 
INSECTS FROM BRITISH HONDURAS. 
The Rev. W. A. Stanton, S. J., of St. Louis University, St. Louis, 
Mo., sent February 12, 1900, for identification certain insects col- 
lected at Belize, British Honduras. The notes which accompanied 
them are of interest. 
An insect known locally as the ‘‘doctor fly” was <dentified as 
Diachlorus ferrugatus Faby. My. Stanton writes: 
The fearful local swelling which follows the bite of these insects causes them to be 
regarded with dread by the inhabitants. The effect, however, varies in different 
individuals.
