EDWARDSIMEMNA; DICOGASTER; MESERA; OMPHALIA. By Dr. M. Draitdt. 573 
7. Genus: Edwarclsimeiiina Neum. & Dyar. 
Distinguished by bare small eyes, a very short cell of the fore wing, from the upper angle of which 7 
and 8 rise on a joint stalk with 6. The basal loop of the hindwing is short, the distal margin somewhat undulating. 
The short palpi are straightly porrect, the abdomen does not project beyond the hindwing. 
Type: E. jalapae Edw. 
E. jalapae Edw. (78 d). Light reddish-brown, the hind-margin and marginal area lighter, more jalapae. 
violettish-grey, with a slightly darker border of the median area, the distal line towards the costal margin 
bordered with whitish; subterminal line somewhat more distinctly dentate. Thorax and abdomen greyer. 
Mexico. 
8. Genus: Dicogaster B. & McD. 
It has likewise bare though much larger and thicker eyes. The wings are shaped as in Quadrina, and 
also have the same veins except that 10 terminates into the apex, 9 below it into the distal margin. 
Type: D. coronada Barnes. 
D. coronada Barnes (78 d) has an exterior almost like that of Q. diazoma , where the differences are coronada. 
mentioned. In the type the red-brown forewing is densely intermixed with whitish grey, the white transverse 
lines are narrowly bordered with red-brown; the strewing may be so dense that the wings almost appear grey. 
— f . valens Dyar is without any grey irroration at all, for which reason the white transverse lines on the deep valens. 
red-brown ground do not appear to be bordered with brown. The larva resembles that of the European quercus, 
being red-brown set with silky white hairs, with yellow stigmata. It lives on Quercus arizonica, hibernates 
almost in its adult stage, and pupates at the end of April in a loose blackish brown web. Arizona; recently 
also reported from Mexico (Michoacan). 
9. Genus: Mesera Wlcr. 
This genus being extremely allied to the following I have nevertheless separated, because it forms 
a good connection of the large preceding genera and the following genus. From Macromphalia it differs in the 
shorter, not so long combed antennae and a small anal tuft in the $. 
Type: M. tristis Wkr. 
M. tristis Wkr. has remained unknown to me, the male with a red-brown body and black antennae has tristis. 
blackish-grey wings, the forewing is somewhat darker and more densely powdered than the hindwing. Length 
of forewing: 12 lines. Venezuela. The $ which, however, surely does not belong hereto, is described to be lighter, 
the forewing with an undulating grey band near the distal margin. Length of forewing: 19 lines. From Bogota. 
M. arpia Schs. (75 e) is in both sexes bright red-brown with a thick black roundish discal spot; arpia. 
in the $ the border of the median area projects twice distally and is distinctly prominent by a postmedian 
brightening, in the d hardly distinct. Anal tuft of $ whitish. Brazil, Argentina. 
M. crassipuncta sp. n. (75 e) has a somewhat obliquer distal margin of the forewing which is somewhat crassipunc- 
lighter and not so bright red-brown; the <$ exhibits a broad dark postmedian band projecting distally on 4 and 7; ta - 
the round discal spot is still larger than in arpia. Described from a from Surinam. Type in the Berlin Museum. 
M. rimicola sp. n. (75 e) is much smaller, monotonously light reddish-brown, with a small blackish rimicola. 
discal spot. Anal tuft light slate-coloured. Described from a $ from Buenos Ayres. Type in the Berlin Museum, 
a similar $ is in Washington in the National Museum. 
10. Genus: Omphalia H.-S. 
This genus must be kept separate, because in the two specimens that are in the Berlin Museum and 
were lying before me (among them the type) veins 7 and 8 of the hindwing are stalked as in the genus Sphinta ; 
they rise only shortly before the cell-angle, in Sphinta near the base. Palpi somewhat longer than in Macromphalia 
with which the other marks correspond. 
Type: 0. psorica H.-S.
