ZYGJENIDJE. 



Alypia disparata, n. sp. — Allied to both A. octoniaculata and A. 

 Wittfcldii, but diftering from both by its more slender form, longer 

 antennae and abdomen, and narrower primaries with more produced 

 apices. There is a strong character in the presence of a very large 

 and distinct vitreous space between costal and sub-costal nervure, caus- 

 ing an enlargement of the costa as in A. Lorqtdnii, and others. The 

 primaries are more than twice as long as broad, greatly produced at 

 apex; the anterior spot is oval, larger than the posterior, which is sub- 

 ovate. The lower wings are like those of A. 8-maculata, the outer 

 spot being quite small, but they are more transparent than in the com- 

 mon species. Otherwise as in A. 8-maailata. i $ . 



Exp. wings 38 mm. Length of body 18 mm. 



Alypia (Agarista) Grotei, Bdv. — Three examples of this rare spe- 

 cies are in the collection, one of which has two spots on secondaries 

 instead of one, as stated by Dr. Boisduval. The thorax also has four 

 pale yellowish spots, two in front on the edge of the collar, and two on 

 the sides. These may have been obliterated in Dr. Boisduval' s exam- 

 ples. I think this is the insect recently described by Grote as Alypioides 

 flavilingids. The tongue in A. Grotei is bright yellow. 



Lycomorpha contermina, n. sp. — Nearly allied to L. p/w/us, but 

 differing in the larger field of orange on the primaries, and the absence 

 of that color on secondaries, except along that portion of the costa 

 hidden by the fore wings when expanded. The orange space of the 

 primaries covers two-thirds ot the wing, its posterior edge being some- 

 what waved. Fore femora and hind tarsi dull buff in front. The 

 remainder of the insect is blue-black. I S . 



Exp. wings 33 mm. Length of body 10 mm. 



Lycomorpha marginata, n. sp. — Wings above and below dull 

 orange, with very narrow black margin to primaries from middle ot 

 costa to near internal angle, the margin being a little widest at the 

 apex. The secondaries have a broader black margin which narrows 

 out as it reaches the anal angle. Thorax and collar orange, rest of 

 body glo.ssy black. i $ . 



Exp. wings 19 mm. Length of body 8 mm. 



Triprocris aversus, n. sp. — Primaries, lower side of all the wings, 

 and upper side of abdomen bright glossy greenish black. Secondaries 

 above, and all the rest of the body dull black. The wings are nar- 

 rower and longer than in any of the allied species. It is nearest to T. 

 atrata, French, from Arizona. i $ . 



Exp. wings 28 mm. Length of body 9 mm. 



Ctenucha votiva, n. sp.— Head, front of thorax, base of patagiae, 

 fore femora, and abdominal tuft bright crimson. Primaries greenish
