Alysia ruskii should perhaps form a new genus near Alysia, 

 but it seems better to leav^e it in Alysia sens, latiss. 



Henades saxosus, n. sp. 



cf — Length about 7}-^ mm., in a rather contracted state, the 

 abdomen strongly convex dorsally in profile; head and thorax dark 

 brown, probably black in life; abdomen lighter and redder; wings 

 hyaline, very faintly dusky; anterior wings 4 mm. long; venation 

 as in H. sauteri from Formosa, except that lower section of basal 

 nervure is more arched, the marginal cell is considerably longer and 

 more pointed, and the bend in the second t.c. is less distinct. As 

 in H. sauteri, the second a. n. squarely meets the second t.c. The 

 following measurements are in microns: Length of marginal cell 

 1152; depth of marginal cell 304; greatest (diagonal) length of first 

 s.m.- 768; second s.m. on marginal, 240; lower side of second s.m. 

 544; second s.m. on first discoidal 80; greatest (diagonal) length of 

 first discoidal about 976. The basal nervure practically meets the 

 transversomedial, which, as usual in Heriadines, is oblique, the 

 lower end most basad. 



Florissant, Colorado, in the Miocene shales; Station 14 (TT'. P. 



Cockerell.) 



Among the fossil bees hitherto found at Florissant, this comes 

 nearest to Heriades laminarum Ckll., but is smaller, with the second 

 r.n. meeting second t.c, and the b.n. hardly falling short of the 

 t.m. The apex of the marginal cell is pointed, if rather obtusely, 

 not rounded. The first r.n. joins the second s.m. at a distance from 

 its base equal to a little over a third of the length of the first t.c, 

 the latter being about 224 microns long. The stigma is well 

 developed. 



CONCERNING THE REPUTED DISASTROUS OCCUR- 

 RENCE OF VANESSA CALIFORNICA IN 

 OREGON AND CALIFORNIA 



BY J. MCDUNNOUGH, DECATUR, ILL. 



In the April number of the Canadian Entomologist, Prof. 

 F. M. Webster of the Bureau of Entomology, Washington, D. C, 

 recounts several instances of devastation of crops and foliage which 

 he attributes to the larvaj of Vanessa californica. A careful study 

 of the various letters quoted convinces us that in all but the last 



July, 1913.
