150 Mr. P. Cameron on some 



the extreme base, luteoiis. At the apex of the first sub- 

 marginal celhile is a large, black horny point. 



Length Z\ lines; alar exp. 9 lines. 



Hah. — Brazil. 



The antennae are strongly compressed and only slightly 

 pilose ; the head is small, and closely attached to the 

 pronotum, and the front is only slightly carinated. 



Trailia nigro-lineata, sp. n. 



?. Pale reddish, the antennte (except the tAvo basal 

 joints beneath), the head (except the part below the 

 antennae), and a line on the outer side of the four posterior 

 tibi[B and tarsi, black. Wings blackish, hyaline at the 

 apex, and there is an irregular clear line in the first sub- 

 marginal cellule ; the costa is luteous at the base. 



Length 4^ lines ; alar exp. 9| lines. 



Hub. — Bahia. 



Comes near to Hylotoma -prcEcox, Kl. (also from 

 Bahia), but it is readily known from it by the reddish 

 pleurte and sternum, the hyaline apex of the wings, and 

 the black-lined tibias and tarsi. 



The antennae are a little compressed, and moderately 

 covered with a pale pile. The anterior tibife have the 

 extreme apex black on the outside, and the two posterior 

 nearly the whole. The posterior tarsi are black, the 

 anterior only black at the apex. The mandibles are 

 piceous. 



RusoBRiA, gen. nov. 

 = Klug's, section 4, of Hylotoma. Yahrb. p. 245. 



Antenna3 somewhat compressed, densely covered with 

 long hair. Epistoma keeled. Wings with one marginal 

 (having an appendicidar cellule) and three submarginal 

 cellules ; the first submarginal cellule long, and it receives 

 a recurrent nervure ; the second small, receiving also a 

 recurrent nervure. The lanceolate cellule is contracted, 

 the basal nervure being very short. The posterior wings 

 are as in Cypliona. The calcaria are long. 



In the form of the antennas and of the head Rusobria 

 agrees Avith Trailia, but differs othei'wise in having an 

 appendicular cellule, and in having the lanceolate cellule 

 constricted. The antenna3 in the males arc forked {teste 

 Klug).
