44 THE CANADIAN ENTOMOLOGIST. 



to Victoria, and also probably west of the Cascade Mountains. I have 

 not seen it from California, or other region. 



The larvae of this genus are exceedingly sluggish, in confinement rest- 

 ing on the grass stems or leaves, and scarcely moving except when the 

 supply of food fails. They are easily bred. I am now feeding larvae of 

 C. Ochracea, and will in due time give report of it. I wish some one in 

 the North-west, interested in these things, would send me eggs of C. In- 

 ornata, a dark brown, or brown-ochre species, with black-brown under 

 side, found along the northern boundary of the U. S. in Dacotah, and in 

 Brit. Am., on the prairies. Eggs can readily be had by confining females 

 over grass in box or fruit can. 



Note. — In my paper on the stages of C. Galacthms, vol. xviii., p. 201, 

 the measurement of the mature larva should read .84 inch (not 1.06 inch). 



ON THE GENUS RICHIA. 



BY A. R. GROTE, BREMEN, GERMANY. 



After examining the European Ammocoiiia caecimacula (in which the 

 ^ antennae are dentate and furnished with pencilled setae or hair ; the 

 form stout ; the tibiae, of the middle and hind legs only, spinose ; the 

 thorax and abdomen with slight dorsal tuftings), I find that my species 

 are not congeneric, and I accordingly refer them to this genus named in 

 memory of a Brooklyn Entomologist, Harvey J. Rich, who died while yet 

 young, and whom I knew " before the war." The type of Richia is 

 Chortalis, and its probable dimorphic form Aratrix, though we do not 

 know quite surely whether the two are so related or not ; they occur over 

 the West and Southwest, to Texas. A second species is the Texan jR. 

 sculptilis of Harvey, a fine Noctuid. A third is my Decipiens, with its 

 red form Farentalis, figured in my Essay. These differ by the untufted 

 abdomen, spinose fore tibiae, the thorax having a ridge of hair (well 

 shown in my figure, Plate i, 13), as also by less robust form, agreeing 

 with Agroiis. The genus, in fact, is not a Hadenoid form, and I refer to 

 my paper on Agroiis, Can. Entom., xv., 54, for my views as to its position. 



I remember determining a fourth species from the West, and others 



doubtless will be found. At present I would thus arrange them : 



Genus Richia Grote. 



Chortalis Harvey. sculptilis Harvey, 



dim. var. aratrix Harv. decipiens Grote. 



var. parentalis Grote.
