Cydosia Tosiisollatilla n. sp. 



Resembles Imilclln, Stretoli, but is a larger insect and otherwise differs in the following particulars: The patagise are orange 

 bronze, in Imililld they are white crossed liy metallic dark blue band. The costa near the base is bronze which is succeeded by a dark 

 blue space extending from the interior to the inner margin and containing three white spots, the niidiUe one the largest, in ImilcUa this 

 bluish space reaches only to the subcostal and contains in my examples but two white spots, anterior to this the costal margin is broadly 

 orange bronze, which color connects with the first bronze transverse band. The large while twin spots at inner niargin between the t.p. 

 and subterniinal bronze bands are horizontally bisected by a dark bbie line, making in this space seven principal while spots instead of 

 five as in Imltrlln, the white spots contained in the dark blue marginal band are very different in shape from those in Imitella, the two 

 principal ones being shaped like a U. Secindarics black, under surface differs from Lniklla on primaries by having a large white discal 

 semilunate spot and a regular white marginal band cut sharply by the black veins, on secondaries are two distinct white apical spots. 

 In two of my examples the end of abdomen is yellow as is ImiteUa, but ia the third the entire abdomen is shining bluish black, which I 

 think is doubtless a sexual difference. 



Expands 1 J to IJ inches. Types, three examples received from Mr. Jacob Knab, who took them at San- 

 tarem, Brazil, some twelve years since. 



Cteiiiiolia Tigrina n. sp. 



Head blue in front, red on top. Palpi (which are broken) are yellow beneath. Throat red. Collar and thorax metallic blue. 

 Tegulse dark brown margined inwardly with ochraceouf. Abdomen above black with a bluish hi.stre, beneath blackish brown. Primaries 

 dark slaty brown as in C. W-no.vi. A pale ochraceons stripe along the costa, a very tine abbreviated one on vein 7, one along vein 6 its 

 whole length t<j the exterior margin, another very broad one extends along the median from the base, forking out on veins 2, 3, and 

 4 to the margin, another extends the whole length of the dorsal vein. Fringe white. Secondaries same brown color as the primaries. 

 Fringe white, smoky about vein 5, but this part of secondaries is damaged. Under surface not as dark as above.. Fringes as above. 



Expands 1 ij inches. Type, one cT from Cartaga, Costa Rica, received from Dr. Van Patten about 1871. 



Close to Venosa, but has the additional yellow streaks on vein 7 and 2, and in tho.se on veins 1, 3, 4, and 

 6 extending to the e.xterior margin and in the entire wiiite fringe of primaries. In these particulars agreeing 

 more with the larger species VUtigera, Blanch. 



&»l>ilo80iiia Atlioiia n. sp. 



Head, body, and wings pure silky white. Palpi dark brown. Antenna; deep black. Fore coxse and femora ochre yellow. 

 Tibia^ and tarsi brown in front, white inwardly. Middle and posterior legs white with tarsi dark brown in front. Primaries with 

 a broken t. p. line composed of indistinct blackish dots, a few blackish scales also at apex and between the t. p. line and the exterior 

 margin. ScKmodaries immaculate. 



Expands 1| inches. Type, one cT received from Bruce, who took it in Colorado. 



This species will readily be known from the allied North American species by the entirely black antennse. 



Spilo.sonia Tlioiia n. sp. 



Head, ])ale ocbraceous. Autcnnne with brown pectinations. Thorax white. Patagia' yellow and edged inwardly with a sharp 

 black line. .Vbdomcn pale ochraceous above, inclined to brownish below. Tarsi and outside of tibiic brown. Primaries white with a 

 slight i)inkisli gray tint. The cnsta edged with blackish scales very slightly near base but more markedly as it nears the apex. A 

 black streak along the median vein to the termination of vein 4, at the junction of the median with vein 2, and with the lower 

 discal vein this streak is heaviest, being there of lanceolate form, half way between the discal vein and the margin of the wing it is 

 broken. .Vnother black ftreak along the inner margin which does not extend to the base or the inner angle. Another on the submedian 

 extending from the exterior margin inwardly one-third of its length. A shorter one on vein 6 some distance from the exterior margin, 

 above this on vein 7 a mere dot. A small spot on the anterior discal vein hnd another smaller exterior to this above vein 4. Secondaries 

 same pinkish white as primaries and immaculate. 



I*]xpand.s H inches. Type, one cf from New Mexico. 



Thi.s sjiecics brings somewhat to mind the much larger and stronger marked S. Clio. 



Parasa I'retiusa n. sp. 



Head and collar bright beautiful green of a more bluish tint than in Viridux, Chloris, Punka, etc. Palpi brown. Patagiae pale 

 ochraceius behind the collar and terminally green. Abdomen white with a slight yellow tint. Primaries bright green. A narrow 

 continuous pale ochraceous band surrounds the wing on all margins, widest on the exterior margin and at the base of wing. Fringe 

 brown. Secondaries silky white with a slight oclirey lint. Whole under surface of wings silky ochraceous white, with light brown on 

 costa and fringe of primaries. 



Expands J inch. Type, one c? taken at Pelropolis, S. Brazil, March 12, 1873, by Mrs. O. C. James, to 

 whose kindness I am indebted for it. 



]Ielorofaiii|>a Aoiiiile)^ n. sp. 



Head and thorax dark brown intermixed with gray. Abdomen gray. Primaries grayish brown. Indications of a t. a. line. A 

 double t. p. line somewhat irregular running much as in LitodnnUi Ihjilromdi, making on the costa two conspicuous black marks extend- 

 ing nearly to the apex. -V lunate bl.ack discal mark. Secondaries pure white except at costa, where they are shaded with brown. Under 

 surface, primaries gray, secondaries white. No markings whatever. 



Expands ]\ inches. Type, one S', taken by A. S. Fuller in New Mexico. 



This .'species will be known from all others by the antennae being pectinated to the extreme end. At 

 first glance this insect might easily be mistaken for Aon Noctuiformis, so close is the superficial resemblance of 

 the two.
