P. dolosa Druce (9 d). Head and thorax (abdomen missing) as well as antenna and legs black, without 
distinct blue gloss; forewing semitransparent, blackish with dark edges; liindwing transparent with blackish 
apex and costal margin; on the underside the costal margin of the hindwing densely clothed with green 
scales. •— Guatemala, only 1 $ known. 
5. Genus: Tetraclonia gen. nov. 
Forewing with only 11 veins, as one of the subcostal branches is absent, in the hindwing 8 veins. 
Very closely allied to Malthaca. —- Genotype: T. saucia sj)ec. nov. 
T. dyraspes Druce (9 d). Very like Acoloithus falsarius, rather larger. Black, wings semitransparent, 
the hairs on the hindwing particularly sparse. Collar yellow, black in the middle. A small species. Connect¬ 
ing vein between costal and subcostal of the hindwing short and very oblicpie. — Mexico: Guerrero. 
T. cinniana Druce (9 d). Body black, thorax anteriorly pale yellow, forewing brownish black, a narrow 
costal stripe, abbreviated distally, and the hindwing pale yellow, hindwing with broad blackish marginal band. 
Venation as before. — Guatemala. 
T. ripena Druce (9 d). Black, frons greyish yellow, collar red, abdomen and wings purple-brown. 
Forewing semitransparent distally between the dark vein-stripes. Hindwing red, with black outer margin. 
Forewing beneath with red longitudinal smear in the basal half. Veins of forewing from the cell; connect¬ 
ing vein between costal and subcostal of hindwing very short. — Bolivia. 
T. latercula Edw. Similar in colour to Malthaca aequalis and correbioides. Forewing red with broad 
black marginal band, which is continued at the hind margin as a thin streak and also extends for a short dist¬ 
ance along the costal margin. Hindwing with red costal margin. — Arizona. 
T. dyari nom. nov. (= laterculae Dyar). Not known to me in nature. According to Dyar the forewing 
has 11 veins. Forewing red with narrow black margin which at the costal and hind margins is produced 
basacl as a short thin streak. Costal margin of hindwing rather broadly red. -— Arizona. 
T. forreri Druce (9 d). Uniformly black, wings semitransparent. Connecting’" vein between costal 
and subcostal of hindwing long. — Mexico: Milpas. In one specimen subcostal 4 is forked, so that 12 veins 
are present. 
T. metallica Schaus. Only known to me from the figure; perhaps belongs to Malthaca. Head and 
thorax black, abdomen dark green. Forewing above greenish black, hindwing metallic blue; underside of 
both wings metallic blue-green. Expanse 30 mm. — Peru. 
T. saucia spec. nov. (9 d). $: Black, everywhere with a fairly strong blue sheen, upperside of forewing 
somewhat greenish. Forecoxa with a small red lateral spot. Forewing slightly transparent, the scales being 
very narrow, and the veins darker than the ground. The connecting vein between the costal and subcostal 
of hindwing short. Antenna pointed, bipectinate, distally dentate, the branches short and pointed, those of 
the central segments only being about half as long as the diameter of the shaft. Length of forewing 14 mm. 
— Cushi, Peru (type), and Yungas de Coroico, Bolivia, two in the Tring Museum. 
6. Genus: Cliiiiogftrocrls gen. nov. 
As in Malthaca both wings with venation complete (forewing 12, hindwing 8 veins), but in the forewing 
subcostal 1 much more proximal than the lower median, while in Malthaca these branches originate from the 
cell at about the same level; none of the veins of the forewing stalked, in the hindwing the costal anastom¬ 
osing with the cell for a shorter or longer distance, the connecting vein between the costal and subcostal 
long, apex of the cell deeply angulate, upper and lower angles truncate, projecting about equally far. Antenna 
of $ bipectinate, that of the $ simple, slightly flattened beneath. — Genotype: Ch. melas Guer. (1839). 
Most easily distinguished from Procris and Pollanisus by the presence of a strong foretibial spur. 
Ch. melas Guer. (9 d). Brownish black, antenna blue, body and upper side of forewing dull dark 
green without gloss, tongue orange-red. On the underside the hindwing and the apex of the forewing faintly 
but distinctly purple-blue. — Chile. 
B. Hindwing with 7 veins (as the 2nd radial = vein 6 is absent). 
7. Genus: Triprocris Grote. 
Frons broad, produced in ring-shape and the frontal surface of this broad swelling somewhat raised
