Zaitha s'p. Three taken 17th April in slow water; another was taken « 

 also, which was being devoured by a specimen of Cybister 

 fimbi'iolatus Say, all the under part of the abdomen having been 

 eaten away. N. O. 



Belostoma amerieanum Leidy. This species has been noticed by Mr. L. 

 O. Howard (Ent. Amer., I,, p. 54) as very abundant in New 

 Orleans, being attracted to the electric lights. I have also 

 referred to this fact in a note in No. 8 of Vol. I. of the same 

 journal. 



PARTIAL- PREPARATORY STAGES OF APATELA 



LOBELIA, GuEN. 



BY G. H. FRENCH, CARBONDALE, ILL. 



Found feeding on a wild cherry, September 19, 1884, two larvse of this 

 species. They were .80 of an inch long, nearly cylindrical, the body 

 somewhat elevated in the middle, from which it tapers a little both ways, . 

 the dorsum of joint 12 with a slight elevation ; eight low tubercles on each 

 joint, from each of which arise a few spreading white hairs. Color 

 green ; a dorsal stripe that is mostly red on joints 3 and 4, and on the 

 elevated portion of joint 12, the rest of the stripe yellow with a reddish 

 blotch to each joint j the anterior part of dorsum of joint 2 red, separatedl 

 by green in the middle, yellowish round the edges. Head slightly bilobed ; 

 the lower part reddish green, the upper part more red. 



September 24th, they moulted when they were i. inch long, the same 

 shape as before. Color dark blackish brown, with a magenta dorsal line 

 bordered each side with black, and a patch of the same color on the top 

 of each lobe of the head. The dorsum of joint 2 is pale instead of 

 magenta. Each joint has twelve small orange tubercles, each supporting 

 a spreading tuft of gray hairs. They pupated October ist, producing 

 two imagines May loth and May 19th, 1885. These are interesting larvae 

 in both of their last larval stages, as the colors are bright. The cherry 

 upon which they fed is the common wild black cherry, Prunus serotina,. 

 the larvae resting when found on the upper side of the leaf.
