THE CANADIAN ENTOMOLOGIST. 115 



Entomologist, Vol. XXXIII., p. 325. The mature larva is smaller than 

 that of virgo, measuring about 35 mm., and when extended 40 mm. ; 

 head black, median suture pale in some specimens, as also the lower half 

 of the epistotna. The skin of the body in some examples is wholly velvety 

 black, in others the same colour but shading to grayish black subventrally, 

 The tubercles are all black, the bristles being distinctly barbed, those from 

 the dorsal tubercles being black, while those from the subventral tubercles 

 are bright rust-red ; prolegs, upper portion black, lower portion reddish. 

 None of the larvae had any markings on the skin. Specimens collected on 

 April 8, at Toronto, only moulted once after coming out of hibernation, 

 and at Montreal, Mr. Brainerd tells me that larvae which he had, moulted 

 only once in the spring before spinning up. From eggs laid in June we 

 reared moths in August, but many of the larvae which were mature (Stage 

 VII.), instead of changing to pupae as the others did, stopped feeding about 

 the middle of August and acted as if they wanted to hibernate. Virgun- 

 cula ought to be bred again to see just to what extent the larvje vary, and 

 if they ever possess the dorsal stripe. The late Mr. T. G. Priddey, of 

 Toronto, made large collections of these larvae, but, unfortunately, did not 

 publish any of his observations. Writing on March 20, 1901, he says: 

 " Now is the time to get Ardia virguncula larvae. The first soft day after 

 the dry grass is released from the frozen snow, they generally show them- 

 selves for a short time, along with Spilosovia virginica, basking on the 

 tops of grass ; after then they are hard to find, as they hide away during 

 the day."

The specimen of the moth which the writer found on the 5th Aug., 

 at Ottawa, was not a complete specimen, but simply one of the primaries 

 of presumably a male, which had become caught in the gauze covering
