Genera and Species of Exotic Trichoptera. 275 
nulated with pale yellowish. Abdomen blackish-fuscous, the 
appendices testaceous. In the male the superior appendices are 
very small, slender at the base and clavate at the apex, hairy ; 
inferior appendices very large and broad, concave, and furnished 
with numerous minute blackish teeth internally, the outer margin 
broadly emarginate ; between the app. inf., on the superior por- 
tion, arises a long flattened and obtuse piece, which I regard as 
the upper penis- cover,

Phryganea divulsa. The type is a female, not a male as is 
represented by Mr. Walker. It is very closely allied to P. 
cinerea, Walker, from Hudson’s Bay, and perhaps identical there- 
with. Nevertheless the locality (Haiti*) renders its distinctness 
possible, and one should see the male to be able to speak with 
certainty. 
Limnophilus griseus, from Haiti, does not differ from the ordi- 
nary European form of that species. The specimen is a male, 
without abdomen. 
Leptocerus niveistigma, L. abjurans and L. quadrifurca, have no 
resemblance to Leptocerus save the long antennze and the narrow 
wings, and do not even belong to the Leptoceride. ‘The neuration 
is identical with that of Macronema, and I consider them as form- 
ing a section of that genus characterized by the narrow and 
elongate anterior wings. In all three species the anterior tibiz 
appear. to be spurless, but the apex of the tibize is very obliquely 
truncated, and drawn out into a point, which might be mistaken 
for a spur, only that it is above, instead of below, the insertion of 
the first tarsal joint. The type of L. quadrifurca is a female, not 
a male as described. 
- * I suppose always that the locality ‘ Haiti’’ is correct; but both this 
insect and Limnephilus griseus are forms that one would scarcely expect to 
find within the tropics.
