Genera and Species of Exotic Trichoptera, 271 
Calcaria 2-4-4. Abdomen robustum; appendicibus inferi- 
oribus ( ¢ ) forcipatis, triarticulatis. (¢ et .) 
Antenne longer than the wings, slender, obsoletely serrated 
within; basal joint very short. Head nearly quadrate above, the 
disk smooth and polished. Ocelli none. Maxillary palpi long 
and hairy ; the basal joint short; the second and fourth equal ; 
the third nearly twice the length of the second ; the fifth very 
slender, thong-shaped, as long as the others united. Labial palpi 
small ; the basal joint short; the second longer; the third very 
slender, much longer than the two others united. Prothorax 
rather distinct. Mesothorax subquadrate. Anterior wings nar- 
row at the base, but broad at the apex ; the apical margin obliquely 
truncated, and very slightly excised just below the apex; hairy 
clothing very slight, whence the wings appear smooth and polished; 
neuration strong and distinct ; discoidal cell closed, rather large ; 
a transverse vein below this cell, another closing the cellula thy- 
ridii, and two others towards the base ; apical forks 1, 2, 3, 4 
and 5 all present, forks 1 and 3 short. Posterior wings as broad 
as the anterior, and but slightly shorter; fringes very short; dis- 
coidal cell closed ; apical forks 1, 2, 3 and 5 present. Legs rather 
short ; the intermediate tibia not dilated in the female. Spurs 
2-4-4; anterior tibiae with two long and equal apical spurs; in- 
termediate and posterior tibiae each with two pairs of long and 
equal median and apical spurs. Abdomen robust; the apex 
obliquely truncated in the female; the male provided with pincer- 
like triarticulate inferior appendices. 
This genus bears a certain amount of resemblance to Hydro- 
psyche, but differs in the nearly-smooth and polished head and 
wings, in the obsoletely serrated antenna, and in the form of the 
palpi, &c. t
