The details of this genus, given in pl. X, are taken from this variety. The mandibles are oblong, with 
the apex oblique and but slightly sinuated (fig. 104); the maxilla are terminated by three ciliated membranous 
lobes, with six-jointed maxillary palpi, the three basal joints gradually increasing slightly in length, the three 
terminal ones longer and subequal (fig. 10); the labial palpi composed of three nearly equal joints (fig. 10d) ; 
the antenna of moderate length, the first joint long, the second and third slightly longer than the fourth ; the 
ungues of the tarsi are slender, nearly straight, with a very small tooth in the middle of the inner edge.
