Another valuable paper is the Catalogue of the Described Aranex 
of North America, by George Marx, which forms No. 782 of the 
Museum Proceedings, and covers about one hundred pages. The 
author deserves the thanks of all arachnologists for this careful piece of 
work. 
Other Museum Proceedings contain descriptions by Mr. Lawrence 
Bruner of New Acrididz, including the characterization of the three 
new genera, Dracotettix, Eritettix, and Boötettix; revision of some 
Taniocampid Genera by John B. Smith; and descriptions of New 
Ichneumonide by William H. Ashmead. 
Professor Alfred Giard has publisned in the Bulletin Scientifique de 
la France and de la Belgique an interesting article entitled Sur 
Quelques Types Remarkables de Champignons Entomophytes. Three 
colored plates, representing Znfomophora saccharina, E.calliphore, E. 
 Plusie, and Polyrhizium leptophyci infesting their respective hosts, ac- 
company the paper. 
The report of the U, S. Entomologist for 1889 contains accounts of 
the Fluted Scale (Zrerya purchas? ), Six-spotted Orange Mite ( Zefrany- 
chus 6-maculatus), Horn Fly (JZematobia serrata), and the Grain 
Aphis (Siphonophora avene). A brief synopsis of the work of the 
division and its agents is given. 
Mr. Lawrence Bruner has published in the Bulletin of the Nebraska 
Experiment Station (Vol. IIL, Article II.) an extended paper on 
Insects Injurious to Young Trees on Tree Claims, which will prove 
useful to western planters. 
A New Phalangium.—In a lot of harvest-spiders received from 
Mr. C. W. Woodworth, Entomologist of the Arkansas Experiment 
Station, I found a number of specimens of a remarkable species of 
Phalangium, in which the sexes are very different, the male having 
extremely long palpi, and the second joint of its chelicere being 
articulated with the first at the middle, so as to form a right angle, 
while in the female the palpi are but little longer than usual, and the 
second joint of the chelicerz is articulated with the first at the end in 
the ordinary manner. The species may be called Phalangium longi- 
palpis. This case is exactly analogous to that of Phalangium opilio of 
Europe, in which the two sexes are similarly distinguished. 
DzscniPTION.— Male.—Body 7 mm. long; 3.5 mm. wide. Palpi 20 
mm, long. Legs: I. 3o mm. ; II. 47 mm.; III. 3o mm. ; IV. 38 mm. 
Dorsum light mottled gray, with a darker central marking beginning 
at the eye eminence, and expanding rapidly to margin of abdomen,
