with a depression in it. The body is black; forehead, shoulders and hips white-spotted; collar and legs blue- 
spotted, the first abdominal ring exhibits a large white dorsal spot, as well as lateral white spots, the rest broad, 
golden green subdorsal stripes. Venter white. Wings extensively black with hyaline spots. Amazon (Para); 
known also from Venezuela and French Guiana. 
M. atavia Hmps. (14 k) differs from varipes by more extensive hyaline spots on the wings, the absence atavia. 
of the dorsal white basal spot on the abdomen, instead of which there are 2 smaller subdorsal spots, and besides 
by the absence of the ventral valve and of the rough scaling on the under surface of the wings, as well as by 
the absence of the enlargement of the posterior tibiae in the $. Amazon (Fonteboa). 
M. flavicinctata Dogn. Black; forehead white, collar and shoulder-covers with metallic green spots; flavicinc- 
a spot on the shoulder and the 3 first abdominal rings above and at the sides yellow, the other black rings ,aia - 
exhibit metallic green lateral stripes. Venter white with black segmental margins. Hips white. Wings black, 
with the same hyaline spots as in varipes, but behind the cell there are 4 instead of 3. Expanse of wings: 28 mm. 
British Guiana. 
M. sectum Kaye. Black; the forehead and spots on the shoulders and at the sides of the venter of sectum. 
the 1st abdominal ring are white. Collar, shoulder-covers and mesothorax with metallic green spots. The abdomen 
exhibits green lateral stripes. The wings are quite black, only the forewings show a small hyaline stripe below 
the cell. Expanse of wings: 28 mm. British Guiana. 
M. albicorpus Kaye. Black with a white-spotted forehead, shoulders and hips. Legs outside with albicorpus. 
metallic green spots. First abdominal ring white, the 2nd bordered with white, both laterally pale metallic 
green; the other black rings are likewise laterally green. The venter shows a broad, white middle stripe and 
short, whitish lateral stripes on the 2 first rings. Wings hyaline with large, black discal and middle spots. Expanse 
of wings: 28 mm. British Guiana in June. 
M. rubricorpus Kaye. Black; forehead white, collar green, base of shoulders with carmine spots, rubricorpus. 
shoulder-covers with metallic green stripes. The 2 first abdominal rings are scarlet, the 3rd to 5th are laterally 
red, the others quite black, laterally scaled metallic green. Wings hyaline with a broad black apex and a large, 
square, black inner-angular spot; costa narrowly, proximal margin broadly black. Hindwings broadly bordered 
with black, the cell being filled up with black. Expanse of wings: 28 mm. British Guiana in April. 
32. Genus: Dixoplilebisi Btlr. 
Only 2 small, sombre-coloured species distinguished by dense, fur-like hair on the radial and median 
veins and the lower subcostal vein of the forewing above. Both median veins rise in common near the lower 
cell-end from which the two lower radial veins rise. 
D. quadristrigata Wkr. (14 k) is a blackish-grey insect with an orange thorax, thinly scaled wings quadristri- 
with oblong hyaline spots in and below the discocellulars. From the Amazon, Minas Geraes, Santos, Sa. gata ' 
Catharina. 
D. holophaea Hmps. (14 k). Unicolorously blackish-grey, otherwise like the preceding species. Guiana, holophaea. 
33. Genus: Plioeiiicostacta Hmps. 
Very closely allied to the following, chiefly differing by the posterior tarsi being above fringed with 
long scales, the upper radial rising from below the upper cell-angle. 
Ph. haematabasis Hmps. (14k) has a blackish-brown body with red spots on the shoulders; the haemataba- 
first abdominal ring exhibits 2 almost contiguous, subdorsal red spots, being otherwise laterally blue-spotted. 
The hyaline spots on the wings are confined by broad blackish-brown margins, and on the forewing by the 
middle spot being connected with the proximal margin. South Brazil (Sa. Catharina, Bio Grande do Sul). 
34. Genus: Iehoria Btlr. 
This genus comprises a small group of species distinguished by mostly entirely scaled forewings in 
which the uppermost subcostal vein rises from the cell; the hindwings are mostly in the middle hyaline dia¬ 
phanous and exhibit a strongly angular discocellular, the lower median vein and the lower radial stand on a 
long footstalk. The straightly porrect palpi extend beyond the forehead. The smooth abdomen shows in the 
<$ on the ventral side a large valve covering the basal segments.
