Chionaspis, which, on examination, proved to be Chiotiaspis minor, 

 Mask. From the appearance of the branch, it occurred to me that the 

 species might be doing harm, and, on writing to Prof. Quaintance, I was 

 informed that it was severely attacking the " China-trees " at Braiden- 

 town, Florida, having apparently killed many trees on the main street of 

 the town. This is the first time this species has been reported from the 

 United States, so far as I can learn, and as it has quite a large number 

 of food plants, its introduction is an important matter. 



Chioiiaspis minor was originally described from New Zealand, and 

 is quite generally distributed in the West Indies. Mr. Alexander Craw 

 has also sent me specimens which arrived at San Francisco, Cal., on an 

 unidentified plant from Panama. The species is known to attack Palm, 

 Vitis vinifera, Rhipogonum scandens, Fersoonia, Hibiscus, Capsicum, 

 Erythrina, and Melia azedarach (China-tree). 



A NEW GRASSHOPPER FROM ONTARIO. 



BY E. 1\I. WALKER, TORONTO. 



Melanopius abortivus, new species. — Size rather small, especially 

 the male. Female nearly as large as M. feiiiur-rubrum, but proportion- 

 ately much stouter. 



Frontal costa nearly reaching the clypeus, subequal, though sometimes 

 a little contracted toward the vertex, plane except a slight depression at 

 the ocellus, or in the male generally slightly sulcate from just above the 

 ocellus, rather thinly punctate. Vertex with the margins slightly elevated, 

 gently expanding in front of the eyes for a distance about equal to or 

 somewhat less than that between the eyes in the female, rather greater in 

 the male. Interspace between the eyes rather broader than the first 

 antennal joint in the male, nearly twice as broad in the female. Eyes 

 rather prominent, especially in the male, of moderate size. Top of head 

 moderately prominent, evenly convex. Antennae about as long as the 

 head and pronotum. Anterior margin of pronotum truncate or very 

 slightly emarginate, posterior margin obtusely rounded. Sides of pro- 

 notum in the male sub-parallel, only slightly divergent posteriorly on the 

 metazona; in the female distinctly divergent throughout their entire length, 

 so that the width of the pronotum is about one-third greater at the pos- 

 terior than at the anterior margin. Dorsum of pronotum broadly convex 

 and more or less distinctly and finely punctate on the metazona. Median 

 carina entirely obliterated or very indistinct on the prozona, distinct and
