Genera and Species of Exotic Trichoptera. 277 
The two genera, Barypenthus and Musarna, may therefore be 
advantageously retained; J. claudens being transferred to Bary- 
penthus, as identical with B. rufipes, and MM. aperiens and M, 
interclusa remaining under Musarna, the former, however, being 
probably identical with B. concolor. M. interclusa appears to be 
distinct from M. aperiens from its universally darker colour, of 
which even the legs and the underside of the abdomen partake. 
Genus Curgia. This is possibly a good new genus, but the 
type of C. braconoides bears extreme resemblance to Chimarra. 
The description is very faulty. The second joint of the maxillary 
palpi does not present ‘a spine at its tip,” as mentioned by Mr. 
Walker; but at that spot there is a tuft of long bristle-like hairs, 
quite analogous to what is found in Chimarra marginata. In the 
diagnosis we find the words “ tibize posteriores calcaribus duobus 
longis apicalibus,” and lower down, ‘tibia posticae calcaribus 
doobus mediis ;” similarly in the description we find the-words 
* posterior tibiae with two long apical spurs,” and lower down 
hind tibiae with two middle spurs ;” the natural supposition is 
that the words “ posteriores” and “ posterior’ were written: by 
mistake for ‘* anteriores” and “anterior,” and this view Dr. Hagen 
appears to have taken, and has thereby been misled into describ- 
ing the spurs, in his ‘* Synopsis Synonymica,” as 2-3-4. In reality 
the anterior tibia are without spurs, and the intermediate tibiz 
have four spurs, instead of three. It is true that in the type- 
specimen, one of the median spurs is broken off from one of the 
intermediate tibige, and on the other one spur is closely pressed 
against the tibi itself, and is difficult to see; but there it is, 
without doubt, and as long as the others. Hence the spurs 
of Curgia (¢) are 0-4-4. The neuration is very similar to that 
of Chimarra marginata, but the cell-like spaces on the disk of 
the wing of that genus are not represented in Curgia ; the apical 
veins are quite the same. Iam not sure that Chzmarra possesses 
a closed discoidal cell in the anterior wings, which is the case-in 
Curgia, although here the transverse veins are transparent, and 
not seen well, except from the underside. The type is a female. 
I repeat that Curgia and Chimarra are very closely allied, and 
jt is possible that if the former be really distinct, some (or all) of the 
described exotic species of the latter should be transferred to it. 
No locality is mentioned for Curgia braconoides ; the type ts 
labelled “ St. Domingo.”
