Description of the Larva of Galerita Janus. 



Head of medium size, flat, semicircular, somewhat enlarged 

 anteriorly, with a short, cylindrical basal neck ; above, sparingly 

 covered with short black hairs ; depressed in the middle ; sides 

 and base rounded, convex ; branches of the Y suture protruded 

 interiorly in the middle, where a small black dot is to be seen, 

 ending inside of the elevated, somewhat cylindrical, anterior 

 angles of the head, where the antenna? are inserted ; above the 

 anterior border, a horny prolongation nearly as long as the head, 

 conical at the base, the apical half bifurcated, each branch with 

 two bristles on the under surface, one nearly terminal, the other 

 a short distance behind the first ; just behind the insertion of 

 the antenna 1 , six oval ocelli arranged around a low, conical ele- 

 vation, in two transverse series, the middle pair more widely 

 separate than the upper or lower ones ; on the Upper surface of 

 the head, within and behind the ocelli, on each side, a longer 

 bristle ; head beneath flat ; on each side near the base, two 

 bristles on short pointed tubercles. 



Antenna? twice as long as the head, of four cylindrical joints, 

 the first nearly equal to the two following united, the second 

 half as long, and the third more than half as long as the first, 

 the fourth very small, lozenge-shaped; the first and second 

 straight, the first with three equidistant interior bristles and two 

 internal and two or three external finer bristles near the apex, 

 the second with one prominent and several finer bristles, the 

 third and fourth joints bent downwards and outwards, with 

 more numerous, very long and fine hairs, in the fourth inserted 

 upon two internal, one external and one terminal tubercles. 



Labium rudimentary, a small, transverse plate, turned back, 

 with rounded angles and under surface densely covered with
