118 SIXTH ANNUAL REPORT 



"i—Larra (Fig. 32)— Length 0.90-1 inch. Bodj' 12-jointotl, proportioneil, 



and with about the same curve as in Eupsalis, but more polished, less wrinkled, more 

 duskj% especially towai-d each end ; the thoracic joints not swollen, and less relatively 

 short, the tirst extending slightly above the head, like a hood ; jts, 10, 11 and 12, each 

 with two narrow, transverse, horny, brown, dorsal ridges, armed with minute thorns, 

 the last ridge on 12 subobsolete : anus on a ventral swelling, between 11 and 12, hav- 

 ing a transverse slit, the hind edge of which is horny and brown, and used as a proleg : 

 12, at end, horny, brown, obliquely truncated above, deeply concave, with two narrow, 

 roughened, darker marks within the concavity, distinctly separated below but meeting 

 above ; the edges notched and furnished with stiff, yellowish hairs ; thoracic legs with 

 the tarsi ornamented with stiff points below, and terminating in a simple claw ; stigmata 

 normally arranged. Head and all the tropi, except jaws, sparsely garnished with stifl" 

 hairs ; of same general form as in Eupsalis, but darker, the lobe of maxill.x- {g) reaching 

 to tip of maxillary palpi, which are 4-jointed ; antenna^ (/) in front, just above mandibles, 

 4-jtd, inclusive of bulbus, jts. subequal in length, the terminal one very narrow and ap- 

 pearing as a fleshy hair ; labium (/<) slender, with 2-jtd. palpi ; mandibles (o) triangular, 

 and but slightly irregular on the inner edge. Described from three specimens. 



We do not yet know what this larva will produce,* but it evidently 

 belongs to the Teiielrioniche, a family which includes our common 

 Meal-worm ( Tenehrio molitor)^ and widely separated from the Bren- 

 thians. 



THE JUMPING SUMACH BEmhY.—Blepharida rhois (Forst.) 

 (Ord. Colkoptera; Fam. CHRYSOMELiDJEf). 



Sumach, on account of its tanning and coloring properties, is 

 coming into increasing use in this country as an article of commerce. 

 Large quantities are imported every year from Europe by New York 

 and Philadelphia houses, and in 1S69 the importations are said to have 

 reached 11,832,451 pounds. Now analysis shows that some of our 

 sumachs possess as much tanning property as the European, and they 

 are so abundant in the South-west that it seems strange that we should 

 have to import any of the prepared article from abroad. There must 

 be a good reason for the fact, however, and it is doubtless to be found 

 in the greater care in which the European article is prepared for 

 market. Sicily sumach is made of the stems and leaves only, which 

 are gathered and carefully dried in the shade, and ground in a primi- 

 tive mill, or cut in a hay-cutter ; the stems are afterward separated by 

 winnowing, and the ground leaves neatly packed in bags. The pre- 

 paration of American sumach, as an industry, is, however, steadily
