published. I have, therefore, taken the 

 liberty of setting aside Mr. Robinson's 

 name in favor of the shorter and equally 

 appropriate one of cyanana. I append a 

 more detailed description of the species. 



Larva. Length 0.50 inch, diameter o.io, 

 cylindrical, tapering slightly in both di- 

 rections from middle, but most posteriorly; 

 color dark green, surface glossy with two 

 shallow wrinkles to each segment, spots 

 minute, blister-like, each giving rise to 

 a fine short hair. A dark vesicular line 

 extends along the dorsum, and on each 

 side below the small dark stigmata, is a 

 pale translucent ridge or fold, bearing an 

 irregular row of light hairs more conspicu- 

 ous here than elsewhere. Head polished, 

 honey-yellow inclining to olive, with a few 

 scattered hairs, palpi white, tipped with 

 crimson. Cervical shield polished, nearly 

 same color as the head, covering top of 

 segment i. Terminal point of thoracic 

 legs black. Prolegs concolorous with gen- 

 eral surface. 



Pupa — enclosed in a pouch-like case 

 formed from a portion of a leaf folded over 

 and lined with silk — elongate oval in form, 

 very pointed posteriorly and of a bright 

 brown color. Each of the abdominal seg- 

 ments is provided with two transverse 

 rows of teeth, the posterior ridge composed 

 of minute, close-set, rasp-like points, while 

 those composing the anterior ridge are 

 longer and more scattered. 



In disclosing the moth the chrysalis pro- 

 trudes itself from its case for nearly its 

 entire length, holding itself in position by 

 the anal hooks. 



Imago — Alar expanse from 0.50 to 0.55. 

 Length 0.22. Head and palpi densely 

 tufted, brown with a slight purplish reflec- 

 tion, eyes grayish blue, antennas short. 

 Thorax with a brown dorsal tuft and dark 

 blue patagia. Abdomen fuscous shading 

 to brown above with a silky lustre ; front 

 and middle legs fuscous inclining to ciner- 

 eous, hind legs silvery cinereous, tarsi annu- 

 lated with pale buff. Front wings dark 

 chocolate-brown and metallic blue ; the 

 latter color predominates in the basal third, 

 but is interrupted about midway by an ir- 

 regular fascia and some scattered flecks of 

 brown ; middle portion of the wing mainly 

 brown, but penetrated from both apical 

 and basal sides with streaks and points of 

 blue ; on the outer third the blue and 

 brown colors are thoroughly intermixed in 

 a somewhat intricate pattern, the apex be- 

 ing brown variegated with four or five ir- 

 regular, blue spots, while the inner angle 



is occupied by a large oblong blue spot 

 divided by an oblique, narrow, brown stripe. 

 The costa presents in a strong light a suc- 

 cession of broad and narrow blue streaks 

 on a purplish-brown ground and on the 

 outer edge is a narrow border of the latter 

 color, while the fringe is of a more or less in- 

 tense blue. Hind wings fuscous, shading to 

 cinereous at base, with a silky lustre, fringe 

 cinereous. Under surface of both front and 

 hind wings f uscous,the former a shade darker 

 than the latter and displaying a faint irides- 

 cence. No sexual differences except the 

 smaller size, the relatively narrower abdo- 

 men, and conspicuous anal tuft of the male.

In the article on the hibernation of the 

 Cotton Worm published in the present 

 number and taken from a forthcoming 

 Bulletin of the U. S. E. C, allusion is 

 repeatedly made to the Southern and 

 Northern portion of the cotton belt. This 

 division is explained in the Introduction 

 to said Bulletin and is made to separate the 

 hibernating and non-hibernating portions. 

 The former, or that we term the Southern 

 portion, may, in a general way and so far 

 as present knowledge permits, be defined 

 as follows : In Texas it embraces that 

 portion of the cotton belt lying south of 

 a line roughly indicated by the Galveston, 

 Harrisburg and San Antonio railroad, ex- 

 cluding, however, the extreme western por- 

 tion and extending somewhat farther north 

 along the river bottoms. Farther east it 

 includes the bottom lands of the Mississippi 

 River, and its tributaries, with its northern 

 limit unknown ; then all south of and in- 

 cluding what is known as the Cane-break 

 region of Alabama ; then the south-western 

 corner of Georgia, and the whole extent of 

 the Florida cotton district ; and, finally, the 

 Sea Islands of Georgia and South Carolina. 



Of the interesting Trichopsenitis depressus 

 Lee. (tribe Tachyporini ; family Staphylini- 

 dce) only a single specimen from Georgia 

 was hitherto known, and nothing of its habits 

 is recorded. Mr. E. A. Schwarz, while in 

 South Texas, found that this species is in- 

 quilinous in the galleries of the common 

 White ant {Ternies Jiavipes). In the same 

 colony of Termes three undescribed and 

 very remarkable Aleocharini were found.
