568 EUTACHYPTERA; CALOECIA; QUADRINA; PRORIFRONS. By Dr. M. Draudt. 
3. Genus : ICutacliyptera B. & McD. 
It has larger hairy eyes, but it is otherwise very similar to Gloveria, only the basal loop of the hindwing 
is somewhat smaller. But one species. 
Type: E. psidii Salle. 
E. psidii Salle (76 b) is the well known Mexican species, from the cocoons of which the so-called 
Mizteca-silk was produced. Forewing red-brown, in the darker, in the $ 1 ghter, more yellowish, with 2 light 
yellowish transverse lines and a small white, in the $ mostly indistinct discal spot between them. Also the 
hindwing of the <$ exhibits a light curved postmedian line. Arizona, Mexico to Guatemala. — The brown larva 
set with silky soft rosy hair lives in colonies of 80 to 100 specimens in a glary white nest extending to one 
meter length, feeding only at night, from October to April on Guayavae and various species of oak. 
4. Genus: Caloecia B. & McD. 
Distinguished from the preceding genus by the veins 4 and 5 of the forewing not being stalked. The 
distal margin of the wings is slightly undulating; otherwise very similar. The <$ exhibits on the anterior tibiae 
a well developed epiphysis, being quite undeveloped in Gloveria. Two species occurring from the southernmost 
parts of North America to Mexico. 
Type: C. juvenalis B. & McD. 
C. juvenalis B. & McD. (78 a) may only be a local form of the following species. Forewing in the 
basal half deep brown, outside densely strewn with grey, with a broad chocolate-brown median band with a 
small white cellular spot in blackish scaling which extends as a longitudinal band from the base almost to the 
subterminal line being composed of black sagittary spots; between it and the distal edge of the median band 
there is another dentate light grey line. Hindwing red-brown with a somewhat lighter distal band. Arizona. 
The $ is lighter and less contrastingly marked. Arizona. 
C. denda Drc. (16d) is on the forewing and hindwing very dark brown, with a small white cellular 
spot and 5 narrow light greyish-brown, more or less distinctly black-edged notched lines, two of which are near 
the base, two being postmedian and the 5th submarginal, the latter with small black sagittary spots, the 
subterminal area being reddish-brown. Hindwing with two feeble reddish-brown lines. Mexico (Jalapa).J 
5. Genus: Quadrina Grt 
Separated from all the neighbouring genera by vein 10 of the forewing terminating distantly remote 
from the apex into the costal margin and vein 9, which is stalked with it, almost directly into the apex. The 
eyes are larger and more projecting than in Caloecia. The basal loop of the hindwing forms a very much 
longer accessory cell, all the rest is as in the preceding genus. But one species. 
Type: Q. diazoma Grt. 
Q. diazoma Grt. (= oweni Barnes) (78 b) is very much like D. coronada and, excepting the morpho¬ 
logical differences, separable by the equally broad median band which in coronada is twice as broad at the costal 
margin as at the hind-margin. Forewing red-brown intermixed with light grey or yellowish-white hair-scales; 
the dark lines bordering on the discal area which forms a somewhat re entering angle on the penultimate 
subcostal branch, are on the averted sides bordered with a somewhat lighter colour; right behind the anterior 
line there is the small white cellular dot; behind the subterminal line, which is bordered by a more or less light 
colour, there is a row of small dark inter nerval spots; New Mexico, Arizona. . 
6. Genus: 3*rorifrons B.&McD. 
A genus containing numerous species part of which are very difficult to identify and very closely allied 
to one another, hitherto found from Mexico to the south as far as Colombia, Bolivia, and Brazil. The genus 
is characterised by the relatively long palpi projecting like beaks or snouts. On the forewing veins 9 and 10 
rise on a short stalk; the former terminates directly into the apex, the latter below it into the distal margin. 
The other veins are as in Quadrina, though 11 and 2 rise nearer at the base; on the hindwing 4 and 5 rise either 
together or on a short stalk from the lower cell angle. — The greatest difficulties were caused by the wrong 
identification of the types; Mr. Schatjs in Washington and Mr. Tams in London, as well as Mr. Joicey, the 
owner of Druce’s types most kindly and largely helped us in clearing up and rectifying these mistakes, and 
we therefore beg to express at this place our special thanks. I think it will be possible by the aid of our
