any otlier specios on acconnt nf tlie ]iromiiiently liandeil alidoincn ; if is one of the 

 very few species named liy Linne whieli lias received oidy one name. Size 

 variable ; onr smallest sjiecimeii (from Jamaica) little more tlniLi half the size 

 of the largest. 



cT. Tenth tergite and sternite of the same length, the tips of the slender 

 sternal processes recurved, not projecting heyond the obtuse ends of the tergal 

 lobes. Harpe long, reaching to middle of clasper, dilated and strongly compressed 

 distally, ajiical part so twisted tiiat its flat side is almost horizontal (or vertical 

 upon the jilane of the clasper). Penis-sheath similar to that of crameri. 



Larva (according to Burmeister, I.e.), yonng : green with an orange dorso-lateral 

 band ; adult : bluish above, greenish at the sides and below, the two colours 

 separated by a pale band running from head to horn ; thorax with a black mesial 

 patch partly encircled with white and red. 

 Pupa marked with black stripes. 



Mr. W. Schaus found another larva at Rinconado, in Mexico, from which he 

 bred specimens identical with cUo excei>t in being rather small. We have dissected 

 one of the iS, and cannot find any difference from the sexual armature of a series 

 of ordinary large ello. We may here have a case of that dichromatism in the 

 larva which is so abundantly found among the Sphinyidde, and of which Sphecodi na 

 ttbhotti is such a striking illustration. Here is Mr. Schans's description : A little 

 smaller than I'Un. Head and first segment pink. Prolegs pinkish, circled with 

 black. Abdominal legs flesh-colour, with black and red circles. Anal clasj)ers and 

 lappets brownish, dotted with white. Body jiurplish grey ; anteriorly on each 

 segment a small black subdorsal spot. The Inrge eye-spot between second and 

 third segments is surrounded with brown, and has jiosteriorly a white transverse 

 spot ; dorsally towards the sides and anteriorly there is on segments 4 to 11 a large 

 black ]iatch, all connected together by fine black lines extending from the head 

 to the horn. Stigmata white. Laterally below the black jiatches there is a 

 brownish baud of mottled red and grey, and anteriorly on each segment two white 

 spots, one above the other. Horn short, conical, reddish, black at the base. 

 Under surface flesh-colour, with numerous small black lines. 

 Gundlach, i.e., describes also two forms of the caterpillar. 



Herr von Bonninghauseu, I.e., maintains that there are two species confounded 

 under ello ; the one, he says, has in both sexes a black streak on the forewiug from 

 the base to the apex. All the ? ? which we have examined were without such 

 a streak. We have not seen BOnninghauseu's supposed streaked ¥ , but we have 

 no doubt that Bcmninghausen's statement is based on a mistake. 



Hah. Tropical and Subtrofjical America, as a wanderer as far north as Canada. 



Very common.

(? ? . Tliis is an Erinw/ix, not an hoyniitliiis. The most robust species of the 

 genus, resembling in this respect some Isogimthus. The transverse zigzag lines 

 of the whitish grey forewiug are sometimes rather distinct. The sexes differ in a 

 similar way as in ello and ohscura. The longitudinal basi-apical streak of the
