Speckled Mountain, Maine (Morse] ; North Madison, Conn., 

 Aug. 19 28 (W. AS*. /?.). I first saw living specimens of this 

 brown short-winged locust on the bare ledges of the Hammonas- 

 set River near North Madison, Conn., in August, 1890, where they 

 were basking in the sunshine in company with SpJiaragemon sa.ra- 

 tilc Morse. It is known definitely only from four or five New 

 England localities, Lake Hopatcong, N. J., and Central, Pa., and is 

 usually found on mountain slopes at a height of 2,500 to 3,300 

 feet, though often on hilltops at much lower levels. Morse (1898, 

 280) states that most of his specimens were taken on Speckled 

 Mountain, Me., where: "It was plentiful, associated with Podisnm 

 yltic'mlix among the various species of Ydcciniuni on the bare up- 

 per portions of the mountain. It is quite alert and agile, when 

 approached springing suddenly and to a considerable distance, 

 sometimes making several leaps in succession. It probably ma- 

 tures in late July or early August as it has been taken on the 

 mountains from August 14 to September 0.'' The Running Lake, 

 Illinois, record of McNeill (1891) was based on a specimen of 

 M. dbovatipennis (Bl.). 



Two of the females at hand, one from Speckled Mountain, the 

 other from North Madison, have the hind margin of pronotum 

 with a distinct median notch, all the others being without trace 

 of such emargination. All the males have the median ridges of 

 supra-anal plate united just beyond the middle, the very narrow 

 median sulcus therefore confined to the basal half of the plate and 

 not percurrent as stated by Scudder (1897, 219) ; the apical third 

 of the plate beyond the ridges being concave, but not silicate. 

 179. MELAXOPLUS ISLAXDICUS Blatchley, 1898a, 196. Island Locust. 



Males slender, size small for the genus; females larger, moderately 

 robust. Dark wood-brown above, greenish-yellow below; antennae uniform 

 pale brownish-yellow. Face, lower halves of lateral lobes and metapleura 

 dull yellow, ivory-white in life. Disk of pronotum dark brown, often with 

 scattered vague dull yellow blotches; the usual dark bar on sides of pro- 

 zona and abdomen distinct in male, vague in female. Hind femora with 

 upper and inner faces faintly, obliquely bifasciate with fuscous. Hind 

 tibiae deep red with a vague black annulus near base. Frontal costa obvi- 

 ously but shallowly sulcate nearly throughout, male, only just below 

 ocellus, female. Prozona but one-fifth longer than metazona, its median 

 carina obsolete or but faintly indicated; lateral carinae distinct on meta- 

 zona, female, scarcely evident, male. Tegmina oval, about one-fourth
