They devour the flowers of golden rod and 

 clover etc. witli great zest. 



All parties at Woods' Holl during the sea- 

 son insist upon it that they had no tempera- 

 ture at all approaching the freezing point. 



I described (Psyche ii, 189) a similar speci- 

 men of A. rottindifoliu — published in Dec, 

 1S7S; and Brunner speaking of the same 

 species in liis Monogr. der Phaneropt. (p. 269) 

 says one Pennsylvania specimen has violet 

 tegmina. He also gives instances of similar 

 variation in other Locustarians. Lewis gives 

 an instance of the same peculiaritv in Cyyto- 

 f'hyUnm i:ojicavum (Proc. Acad. nat. sc. 

 Philad., 1SS3, 44). Samuel H. Sctidder. 



McNeill on Tkvx.\linae. — The Daven- 

 port academy of natural sciences has just 

 published, in an octavo pamphlet of 96 

 pages and six admirable plates, Prof. J. Mc- 

 Neill's Revision of the Truxalinae of North 

 America. It is one of the most important 

 pieces of recent work done on North Ameri- 

 can Orthoptera by American entomologists; 

 for the Tryxalinae have been one of our least 

 known though richest groups. The classifi- 

 cation is an independent one and does not 

 follow verj' closely the features of Brunner's 

 general outline for the Tryxalinae of the 

 world given four years ago, and which con- 

 tained a relatively small portion of the gen- 

 era here recognized by McNeill. Altogether 

 75 species are entered, referred to 31 genera, 

 of which II are proposed as new. Only ten 

 new species are described, which is an aston- 

 ishingly small number for the country, since 

 several new forms have been found in the 

 East within recent years, and a great deal re- 

 mains to be done even here. A full figure, 

 generallv with considerable additional detail 



is given for every genus, but unfortunately 

 the enlargetnent above nature is not indi- 

 cated The memoir places our small grass- 

 hoppers on a ver^' different basis from that 

 on which they have hitherto stood, and the 

 figures alone are a striking addition to our 

 means of study and determination. 



A GE.M'S OF GrYLLIDAE HITHERTO VNRE- 

 CORDED FROM THE UNITED STATES. — I 



have recently received from Mrs. Annie 

 Trumbull Slosson specimens obtained in 

 southern Florida of a new species of Mogo- 

 siplistus, which may be called ]\1. slosso'ii. — 

 It differs from all known species in its long 

 pronotum, which is considerably longer than 

 broad, a little broader posteriorly than an- 

 teriorly, the lateral canthi rounded, the pos- 

 terior margin truncate, straight, tlie lateral 

 lobes equally rounded anteriorly and posteri- 

 orly ; the first joint of the hind tarsi is elon- 

 gate and much more than twice as long as 

 tlie hind tibial calcaria; the ovipositor as 

 long as the hind tibia and tarsi taken 

 together. The body is covered with gray 

 scales, beneath which the thorax is testaceous 

 and the abdomen Ijlack; the central portion 

 of the outer face of the hind femora is also 

 black; antennae castaneous. Length of 

 body, $ 7.5 mm; ovipositor, 5 mm. Bis- 

 cayne Bay, Fla.. under bark of trees. 



Mrs. Slosson writes that they are silvery 

 and iridescent in life, and very agile and 

 were found wherever she tore otT bark from 

 fallen trees. 



The genus has been heretofore known in 

 America only from Chili, the species from 

 Cape St. Lucas Lower California referred 

 here (Mogoplistes) by me belonging else- 

 where. Samuel H. Sniddey.
