entirely yellowish. Abdomen often blood-brown, except at base and 

 tip. Tip of ovipositor and of tarsi dusky. Elytra pale yellowish ; on 

 the middle of the oosta an oblique rhomboidal black spot ; on the 

 costal tip a black dot, and on the interior margin, forming a triangle with 

 the other two spots, a black spot ; a blood-brown, irregular, broad stripe, 

 covering the humerus, thence running to the interior margin ; thence, 

 in a zigzag dii-ection, to the rhomboidal spot ; thence to the spot on the 

 interior margin ; thence not quite attaining the terminal dot. Wings 

 hyaline ; tips of costal veins often dusky. Length to tip of wings, a 

 little over one-tenth inch. Occurs abundantly on the grape-vine. 



Erjjthroneura oc!o-notata (the eight-spotted leaf-hopper.) Whitish. 

 Head as in the preceding. Thorax a little clouded with fuscous. Ab- 

 dominal and ventral joints, in mature specimens, dusky, except at tip. 

 Tips of tarsi dusky. Elytra whitish-subhyaline, with the same three 

 spots as the preceding, and, in addition, one on the inner margin 

 not far from the base ; on the cross-veins, an irregular fuscous band, 

 and on the disk a small brown cloud, often obsolete. Length a little 

 over one-tenth inch. Occurred sparingly on the grape-vine, along 

 with a few E. vulnerata Fitch, and numerous specimens of the preced- 

 ing, andof ii. vitis Harris, and tricincta Fitch. Dr. Fitch has suggest- 

 ed that these last two species may be mere varieties. I have examined 

 some dozen specimens of each, and find that there are no intermediate 

 grades. 



It may, perhaps, be worth while to add, that on the grape-vine 

 where these Erythroneurce were swarming, I noticed a small and rather 

 rare dipterous fly, the Hemerodromia superstitiosa of Say, very busily 

 engaged. I caught him and put him in my collecting bottle, along 

 with a number of the leaf-hoppers, and shortly afterwards saw him ap- 

 proach one slyly, stick his beak into it and suck it to death, without 

 previously using his long raptorial front legs." (Prairie Farmer, Sept. 

 6, 1862, with the figures given above.) 



Aphis Maidis ? Fitch, infests the roots of young Indian corn, as 

 well as the stems of the roasting ears. (Jour. III. State Agr. Soc, 

 Sept., 1862, pp. 8-13, with figures.)

Capt. N. E. Atwood, of Provincetown, gave some interest- 

 ing statements relative to the Cod Fishery of our coast. In 

 response to a question of Mr. Putnam, he said he thought 

 the Cod of the Newfoundland Banks to be distinct from that 

 of Massachusetts Bay, and remarked, tliat upon the Banks
