Genera and Species of Exotic Trichoptera. 253 
Fam. LEPTOCERID. 
Genus GaNnoneMa, nov. gen. 
Antenne longiores, tenuiores; articulo primo inflato. Caput 
fere quadratum, inter antennas productum. Ocelli nulli. 
Palpi maxillares hirsuti; articulo primo brevi; 2° quam 1° 
longiori; 3° quam 2° vix breviori; 4° quam 8° breviori; 5° 
tenui, 3° quali. Ala anticee pube brevi sparse vestite, 
apicem versus valde dilatatz ; margine costali arcuato, apicali 
oblique rotundato; radio et sectore apicali primo confluenti- 
bus; cellula discoidali elongata, angustata, occlusa; ale 
posticee fere dimidio breviores; cellula discoidali aperta, 
Calearia 2-4-4. Abdomen robustum. (@.) 
Antennz very long and slender, more than twice the length of 
the wings; basal joint bulbous, scarcely so long as the head. 
Head nearly quadrate, produced into a broadly triangular pro- 
longation between the antenne, and with a deep excavation near 
the eyes, below the basal joints of the antenna. Eyes large. 
Ocelli none. Maxillary palpi very hairy; the basal joint short; 
the second very long; the third slightly shorter than the second; 
the fourth much shorter than the third; the fifth about the length 
of the third, thinner and flexible. Prothorax scarcely evident. 
Mesothorax ovate, convex, sulcated in the middle above, scarcely 
hairy. Anterior wings rather broad, much dilated towards the 
apex; the hairy clothing slight, most dense along the costal margin ; 
apical fringes very short; costa arched; apical margin obliquely 
rounded, nearly elliptical ; dorsal margin concave ; radius straight, 
confluent with the first apical sector shortly before its termination ; 
discoidal cell long and narrow, closed, the apical half deeply 
excised on the upper margin from the point where the first apical 
sector branches off; first apical cell much longer than the sue- 
ceeding ones; the inferior branch of the ramus discoidalis ending 
in three apical sectors; cellula thyridii long and narrow, closed 
by one transverse vein, and united to the lower edge of the dis- 
evidal cell by another, Posterior wings short, scarcely half the 
length of the anterior, broad, the costal margin slightly rounded ; 
radius confluent with the first apical sector, as in the anterior wings ; 
discoidal cell open; apical forks four. Legs very slender. Spurs 
2-4-4; anterior tibize with a pair of minute apical spurs; inter- 
mediate and posterior tibiae each with two pairs of rather long 
and unequal spurs. Abdomen robust. 
The neuration of the male probably differs in the inferior branch
