ORTHOPTERA— LOCUSTIDAE— LOCUST A FULIGINOSA. 907 



specimen presented to me by Dr. Palmer, who obtained it in Arizona. From 

 it I am enabled to set at rest all doubts in regard to the distinction between 

 L. fuliginosa and L. occidentalis. The specimen before me shows very 

 clearly and beyond dispute that the two are quite distinct; the long wings 

 and elytra and the peculiar color of the wings being the same in the female 

 as the male. 



The general color is ashy-white. The occiput is striped longitudinally 

 with white and cinereous; the pronotum is similarly striped on the dorsum, 

 the lower portion of the sides being bordered with yellow. The numerous 

 reticulate veinlets of the elytra are white, giving them the appearance of 

 being sprinkled over with fine white powder. The wings in the female are 

 similar in color and reticulation as described in the male, and as figured by 

 Professor Glover in the report above referred to. The posterior legs (the 

 only ones remaining) are of a pale ash color, with a. purplish tinge. Ovi- 

 positor ash-brown, curving slightly downward at the apex. 



Dimensions. — Length of body about 1.25 inches; length to tip of elytra, 

 2.25 inches; elytra, 2.0 inches; posterior femora, 1.4 inches; posterior tibia?, 

 1.4 inches; ovipositor, 1.25 inches. 



As this was the first species of Locusta known to our fauna, and the 

 first specimen, badly damaged and alcoholic, this specimen in color, although 

 also somewhat imperfect, is one of the most interesting of the collection to 

 me. It not only enables me to complete my description, but also confirms 

 the view I took in regard to the distinction between this and the one from 

 California. 



There are some other specimens of Loatstidce, chiefly Xiphidium and 

 allied genera, which I am unable at present to determine with certainty ; 

 also a few Gryttidce in the same condition; in fact, it is almost impossible 

 to arrive at any certainty in regard to the crickets until there is a revision 

 of this family. I will try and determine them, and report next summer, 

 when I trust I shall have materials for comparison and some works of 

 reference, which I do not have access to at present.
