A MEXICAX KISSIXG BUG. 



Under date of September 12, 1904, Prof. A. L. Herrera, Comision 

 de Parasitologia Agricola, Mexico, D. F., wrote that a large form 

 of bug commonly known in that country as '* chinche voladora," a 

 specimen of which he furnished and which proves to be Meccus pal- 

 lidipennis, Stal., is the cause of considerable apprehension of serious 

 injury, especially to children which it attacks by puncturing the skin 

 with the beak and sucking the blood. 



The species is a reduviid, larger than our native so-called '' kiss- 

 ing bugs," and is closely related to Conorhinus, the genus wliich 

 includes the cone-noses, our most bloodthirsty species. It measures 

 upward of 1| inches in lengtli, and is five-eighths of an mch wide 

 across the middle of the abdoinen. It is black, with two triangular 

 bands converging at the apex of the scutellum, while each segment of 

 the connexivum or reflexed sides of the abdomen which border the 

 tegmina is variegated with white, resembling the markings of certain 

 of our common turtles. ' Its beak is a little longer than the elongate, 

 pointed head. The insect is so large and of such formidable appear- 

 ance that we would naturally expect it to be capable of a dangerous 

 '• bite." 



HYDEOC'YAXIC-ACID GAS AGAIXST THE BEDBUG. 



March 17, .1905, Eev. Enter AV. Springer, chaplain. U. S. Army, 

 Fort AVashington, Md., states that he has used the hydrgcyanic-acid 

 gas process for the extirpation of the bedbug in the barrack buildings 

 of that fort with considerable success. He reports as follows : 



The experiment was first tried in a large barrack building, according to direc- 

 tions. Several receptacles were broken in mixing the acid, but the intended 

 results were perfectly satisfactory. Since then my own residence was twice 

 invaded, beyond the reach of ordinary remedies. In each case the effort at 

 relief was perfectly successful. The last time a half a dozen insects were cap-
