HAEMACTIS; DIPHOEIDAS; GORGYTHION; ANISOCHORIA. By Dr. M. Draxjdt. 909 



C. thrasybulus F. (177 c) is above violettish-black with velvety-black dentate lines, beneath move tJirasybulw. 

 reddish-brown with duller markings, and in the cJ with a lighter, lilac-grey apex and a lighter proximal margin 

 of the forewing. Very common from Mexico to Southern Brazil. 



C. caeruleonigra Mob. is very similar, somewhat smaller, the dentate lines more coherent. Beneath caeruleo- 

 black, at the costal margin and apex reddish-brown, the base of the costal margin and the proximal half of ntgra. 

 the cell as far as the proximal margin of a pure bluish-white; distal margin of hindwing reddish-brown, 



more or less dusted light blue. Guiana. 



45. Genus: Maemactis Mab. 



Antennae short, slender with a small, bent club; terminal joint of palpus almost as long as the second, 

 bent forward. Forewing elongate, produced on the lower radial vein, below the apex concave, like the hindwing. 

 The bare posterior tibiae exhibit only one pair of spurs. Only one species: 



H. sanguinalis DM. <& Hew. (177 d) is a small, black and red species resembling certain Erycinidae sanguinalis. 

 and not to be mistaken for any other species. Ecuador and Bolivia. 



46. Genus: Diphoridas G. u. S. 



Allied to the preceding genera. Terminal joint of palpus still longer, the margin of the forewing more 

 convex, below the apex and above the proximal margin somewhat concave, costal margin before the apex 

 likewise slightly concave. Costal fold absent. Posterior tibiae with 2 pair of spurs and a hair-pencil. 



D. phalaenoides Hbn. (177 c) is a common, small species with similar characters of the marking as phalaenoi- 

 in Cyclogypha, but the transverse lines are finer, more numerous and particularly prominent as a bent ante- ^'^^^ 

 median transverse line and towards the distal margin near the proximal angle; apical half of the costal margin 



on the hindwing much darker. Beneath of a duller brown, more monotonous, in the anal half of the hindwing 

 occasionally somewhat lighter lilac-grey. Mexico to Paraguay. 



D. palpalis Latr. (= aura Plotz, dichrous 3Iab.) (177 d) is very similar, somewhat larger, hindwing palpaU.s. 

 more brownish, beneath in the anal half whitish. Panama to Brazil. 



47. Genus: Crorgythion G. u. S. 



Very similar to the preceding genera, the palpi not quite so long, the shape of the wings broader, at 

 the distal margin less concave, the apex somewhat stunted. Otherwise the same as in Diphoridas. 



G. pyralina MscMr. (177 d) is light violettish-br own with black macular bands particularly prominent pyralina. 

 in the anal half of the forewing in the shape of spots, above them in a row of spots 3 or 4 spots are strewn 

 with bluish- white; 2 minute subapical hyaline dots. Beneath duller greyish-brown. Common from Mexico 

 to Southern Brazil. — ■ f. marginata Schs. (177 d) presumably belongs hereto; it differs by the broad blackish- margmata. 

 brown margin of the hindwing. Described according to 2 Peruvian specimens. 



G. begga Prittiv. (= alcandra Mah.) (177 d) is abo\e scarcely separable from the preceding, but iegga. 

 the hindwing above is blacker towards the apex; the chief mark, however, is the hindwing beneath being whitish 

 in the anal half. Mostly common from Panama to Paraguay. 



G. beggina Mob. (177 d) is above much lighter, light yellowish-violet, whereby the macular bands beggina. 

 are much more conspicuous than in the other species; the markings are otherwise almost the same. The hindwing 

 is beneath in the anal half still purer and more extensively white with more feebly prominent markings. Bolivia. 



G. beggoides Schs. is another very closely allied species. Above greyish-brown, with similar macular beggoid^. 

 markings as the others, but more confluent; the postcellular row of spots consists of large, elongate spots bet- 

 ween the veins; the m.arginal spots are confluent towards the apex; subapical spots entirely absent; on the 

 light brown hindwing the dark markings are nearly all broadly flown together. Beneath also the forewing shows 

 whitish at the apex and proximal angle, the hindwing a broad white proximal margin and anal angle, white 

 spots in the cell and at the cell-end, and whitish diffuse patches before and on the m_argin. Expanse of wings: 

 15 mm. An insular form from Trinidad. 



48. Genus: Aiiisochoria Jfa&. 



Distinguished by very long, beak-shaped palpi; antennal club strong, curved bow-like and finelj" pointed. 

 Costal margin of forewing strongly convex, the apex appearing somewhat stunted. Costal fold absent. Border 

 of hindwing regularly rounded. Posterior tibiae with 2 pair of spurs. 



A. polysticta Mab. (= lemur Mschlr.) (177 d,e). Above brownish-black, Avith an oblique row oi polysfida. 

 6 very small white hyaline spots from the middle of the costal margin to the proximal angle, 3 small apical 

 spots and 2 or 3 below them. Beneath somewhat lighter brown, in the distal part of the fore^idng still lighter, 

 in the apex somewhat reddish. Hindwing lilac-grey, watered blackish, with 3 faded brownish transverse bands 

 and ferruginous spots below the costal margin. Common from Mexico to Guiana and Peru. Southera specimens 

 are mostly much darker, the small discal hyaline spots almost disappearing, beneath on the hindwmg appear 

 larger chestnut spots.
