shorter limbs than in Phalangopsis. The surface of the body is gen- 

 erally smooth, but posteriorly, and particularly in the male, there are 

 minute short spines, which give to that region a granulated appearance ; 

 these minute spines are especially crowded upon the margin of the 

 segments or articulations. The femora are provided with spines above 

 and below, stronger below, and more so in the male. The tibial spines 

 are very much developed on the anterior and posterior tibiae, much less 

 on the medial oaes ; anteriorly they occupy the outer edge of the limbs, 

 and answer fossorial purposes ; posteriorly they constitute two rows* 

 directed horizontally backwards, inclining a little downwards, the inner 

 row being the strongest. The anterior and posterior tarsi are trimerous ; 

 the medial ones being tetramerous. The ovipositor is comparatively 

 small; its length being less than the half of the length of the body, 

 and provided beneath and towards the tip with from eight to ten small 

 spines. 



The ground-color is chestnut-brown, mottled above with lighter shades. 

 The antennas and spines are blackish. 



Specimens were collected at the Camp No. *7, recorded as "yellowish-- 

 brown ;" others on June 5th and 6th, said to be "yellowish-red." .

II. ANABRUS, Hald. 



Gen. Char. — Body sub-cylindrical, thickest in the middle ; without 

 wings ; antennas almost as long as the body, and filiform ; pronotum 

 selliform, extending over the basal articulation of the abdomen, and con- 

 cealing rudimentary elytra ; ovipositor elongated, nearly straight, sword- 

 shaped ; tarsi broad, soles concave ; third articulation cordate.

 App. C, 370. 



Obs. — The general appearance of the genus Anabrus reminds us 

 strongly of Phalangopsis proper, from which it is distinguished by its 

 movable and selliform pronotum and the length and shape of the 

 ovipositor. The general proportions of the body and limbs are more 

 elongated than in Phalangopsis. The structure of the tarsi, which is
