144 Mr. P. Cameron on some 



base of the mandibles. The antennie are situated imme- 

 diately over the clypeus, which is small, and broadly but 

 not deeply incised ; the labrum is large, broad, and semi- 

 truncated at the apex. The thorax is globular ; the lobes 

 of the mesonotum are very distinct ; the scutellum is broad, 

 almost truncated in front, narrowed and rounded behind, 

 and distinctly separated from the surrounding parts, over- 

 hanging the cenchri. Abdomen longer than the head and 

 thorax, carinated in the middle above, and semi-truncated 

 at the apex. Legs moderately long ; the posterior tibiae 

 bear a single spine near the middle ; the tarsi are a little 

 longer than the tibite ; the basal joint is longer than all the 

 others combined ; the three following are nearly equal ; 

 the last is as long as the preceding three, and terminated 

 in long curved sharp single claws. The wings have one 

 marginal and four submarginal cellules ; the first sub- 

 marginal is small, the second a very little longer, and 

 receives a recurrent nervure near its centre ; the third is 

 a quarter longer than the second, and forms nearly a 

 parallelogram, and receives one recurrent nervure ; the 

 fourth is longer than all the rest. The marginal cellule 

 has a nervure surrounding its upper border, and which 

 forms at its termination a very small appendicular cellule. 

 In the posterior wings there is also a surrounding nervure, 

 ending in an appendicular cellule, which is slightly better 

 marked than the one in the upper ^vings. There is one 

 dividing nervure in the middle cellule (in the posterior 

 wing) as in Cephalocera. 



In some respects this genus comes very near to Cepha- 

 locera, but it may be at once distinguished therefrom by 

 the pilose, non-clavate antennje, the last joint especially 

 being conical, and if anything thinner than the 6th; while 

 in Cephalocera the 7th joint is thickened out into a dis- 

 tinct club, the joints being also bare. There is also an 

 appendicular cellule in the posterior wing, while there is 

 none in the other. 



Beyond the non-clavate antennae I see no reason why 

 this genus should not be included among the Cimbicina, 

 if Cephalocera and Syzygonia are to be included among 

 them. Incalia forms a connecting link Avith the Hylo- 

 tomina.
