1, Euantha dives. (Tab. VI. figg. 4; 4a, head.) 
Dexia dives, Wiedem. Aussereur. zweifl. Ins, ii. p. 377. no. 15. 
Sericocera pictipennis, Macq. Dipt. Exot. ii. 3, p. 67, t. 7. fig. 5. 
Head yellowish-white; in the male the hind portion of the front half as broad, in the female nearly of the 
same width, as the eyes; frontal band black; cheeks beneath the eyes with a subtrigonal blackish spot ; 
beard yellowish. Antennze—of the male rufous, with the third joint somewhat infuscated towards the tip, 
this joint at least twice as long as the second,—that of the female blackish ; arista rufous in both sexes. 
Proboscis brown ; palpi rufous, in the female darker or even black. Thoracic dorsum whitish- or yellowish- 
grey, with two sharply limited black bands which do not fully reach the posterior margin of the thorax ; 
pleure black, with a perpendicular, large, whitish median band ; scutellum light grey, blackish at the base. 
Abdomen of the male black, laterally with yellow, somewhat transparent portions, which occupy the whole 
second segment and a part of the first and third segments; the second and third segments have greyish 
front borders, and the anal segment has a large dorsal spot of the same colour; on the ventral side is a 
whitish or yellowish pilosity; first segment on the dorsal part with two marginal macrochete; the 
following segments with discal and marginal macrochete ; the lateral macrochete are at the hind margins, 
but the first segment also has a pair of them behind the middle. The abdomen of the female is black, 
without any yellow coloration at the sides; the light grey front borders of the median segments and the 
dorsal spot on the anal segment are more conspicuous; the yellowigh pile on the ventral side is absent ; 
the disposition of the macrochete is quite the same as in the male. Coxe black, on the front side with 
silvery-white reflections ; femora and tibie yellowish-rufous, the tibiz, especially the hind ones, usually 
somewhat infuscated, the tarsi black; in the female the femora are blackish towards the tip and the tibie 
nearly as dark as the tarsi. Tegule yellowish. Wings brownish-yellow at the base and along the costa; 
the veins, or at least some of them, broadly bordered with dark brown ; small cross-vein on the middle 
of the discal cell ; apical and posterior cross-veins slightly curved, in some specimens straight. 
Length 12:5 millim. 
Hab. Nortu America, Kentucky, Philadelphia.—Mexico, Chilpancingo 4600 feet, 
Amula 6000 feet, and Omilteme 8000 feet, all in Guerrero (H. H. Smith); GuatEMata, 
Chiacam in Vera Paz (Champion). 
Two male and six female specimens. 
Wiedemann considered his specimen to be a female, but his description, especially 
so far as it concerns the coloration of the abdomen, seems to indicate the male ; pro- 
bably he was mistaken as to the sex, owing to the short foot-claws and pulvilli. 
Macquart mentions both sexes; his figure, which in more than one respect is inaccurate, 
shows erroneously the foot-claws and pulvilli elongate.

This species, of which the collections before me contain only females, is closely allied to £. dives. It agrees 
with it in size, but has a more obscure aspect. The front is a little broader than that of the females of 
E. dives, and shining black, the black frontal band thus being less conspicuous; close to the frontal bristles 
is a pair of orbital bristles, which are directed forward (these being absent in H. dives); the face and 
cheeks have more silvery-white reflections ; the scutellum is black; the front borders of the second and 
following abdominal segments are not grey, but silvery-white and less sharply delineated. The pattern 
of the wings is quite similar to that of H. dives, and also varies in the different individuals, but is usually 
somewhat darker.
