with a small beetle [Mononychus vulpeculus), in all its stages. The larvse and 

 pupse were waxen in appearance. The beetle was a trim and handsome little in- 

 sect. The following is a description of it : — Length, 5 millimetres ; breadth, 3 mil- 

 limetres. Color above, deep seal-brown. Elytra and thorax bordered with yellow. 

 Thorax granulated. Elytra roughly striated. Eyes small and black, close to the 

 proboscis . 



Color beneath, that of burnt sienna on the sides, and grey under the abdomen 

 and between the legs. Femora and tibise furry. Femur stout, somewhat flask- 

 shaped. Tarsi ending with two pads or cushions, side by side, with a claw between 

 them. Joints of tarsi very distinct. 



Proboscis extending between the front pair of legs, as far as the middle pair; 

 blunt, scaly — the upper part sienna-colored; the lower, dark grey. 



I am indebted to the kindness of Dr. Howard and Prof. Schwarz, of the 

 U. S. Bureau of Entomology, for the determination of the beetle. 



I obtained from the affected Iris pods a considerable number of specimens of 

 the parasite Pimpla inquisitor, Say. 



Hemiptera on the Milk Vetch. 



On September 1st, on a small patch of Milk Vetch (Astragalus canadensis), 

 growing at Aylmer, Province Quebec, I found no less than six kinds of bugs. 

 Amongst them were: — Alydus conspersus, Mont., and Megalotomus quinquespinosus, 

 Say. 



A. conspersus is black with an orange patch on the abdomen above. This can 

 be seen only when the wings are spread. 



M. quinquespinosus is a handsome insect, of a neat ochreous color. Its abdo- 

 men has black edges marked with pale yellow spots. It was named from the five 

 spines on the femur of each of its hindmost legs. 



For the identification of these two bugs I am indebted to Prof. Heidemann. 



Basilona imperialis, Drury. 



On October 2nd, Miss Effie Garrioch sent me, from Marshall's Bay, on the 

 Ontario side of the Ottawa, three larvae of Basilona imperialis. They were full 

 fed, and went into the earth on the evening of their arrival. Two of them were 

 of the deep green of the pine foliage; the other was of a rich rosy brown. They 

 changed to pupae on the 10th of the month. The following is a description of 

 these remarkably handsome caterpillars: — Length, 3 inches; diameter, 5-6 inch. 

 Head lobed, black, with clay-yellow upright markings in front, and paler yellow 

 marks on the sides. 



Forelegs, clay-yellow with black tips. Prop-legs, dark brown with a clay- 

 yellow bar across them. 



Body color a dark green — sometimes a rosy brown — ^with a purple dorsal-line, 

 and a broad faintly purple band along each side. 



The second segment has a black shield with four glossy warts on the front edge 

 of it. 



On the third, and again on the fourth, segment are two prominent warts, 

 one on each side of the dorsal-line, pale yellow at the base and tip, and black, spotted 

 with yellow, in the middle. In line with each of these pairs of warts, and on the 

 seven next following segments, are creamy-white, pointed warts — one on either 

 side of each of the segments. On the twelfth segment, at the top, is a glossy black,
