with somewhat coarse closelj-set punctures, whicli become 

 smaller below and are absent on the cheeks below the eyes ; 

 face and cheeks clothed with silvery-white pile, which is very 

 sparse on the former, but thicker on the latter, and partially 

 conceals the oral cleft ; a curved shining black mark on each 

 side of the antennary pit below, continued backwards as a 

 narrow incised line on each side of the contracted portion, and 

 ending in a small triangular shining spot on each side of the 

 commencement of the wider portion of the oral cleft; between 

 each of these spots and the eye, and nearer the latter, a con- 

 spicuous, sharply defined, and somewhat rounder shining spot, 

 while in the same straight line and close to the orbit lies a 

 much smaller and less distinct fleck, above which and halfway 

 between it and the transverse shining spot already mentioned 

 is a similar mark ; the extremity of the vertical arc of the 

 fissura frontalis on each side dull black ; occiput clothed with 

 silvery-white pile ; occipital orbits silvery white. 



Thorax and sciitellum thinly clothed above with short black 

 pile, which becomes more conspicuous and forms a distinct 

 longitudinal stripe above the thick white pile of the pleurae ; 

 pectus also clothed with thick white pile ; posterior border of 

 the sciitellum thinly clothed beneath with whitish pile, which 

 projects beyond the margin, and so gives the scutelluin a 

 whitish rim. 



Abdomen coarsely granular above; posterior border of 

 third, fourth, and fifth segments and that of the second on the 

 sides narrowly shining black ; upper surface thinly clothed 

 with short black hairs ; basal angles in the typical specimen 

 clothed with longer silvery-white pile, in front of which is a 

 little black pile, while the basal angles are connected by a 

 semilunar band of silvery-white pile, which conceals the hind 

 margin of the second segment, and in the median line projects 

 on to the third segment, which is clothed in the centre behind 

 this projection with brownish pile ; in the other specimen the 

 longer pile on the second segment is for the most part 

 brownish, a little paler and thinner in the middle of the hind 

 margin, while there is more black pile on the sides of the 

 segment in front ; ventral groove thickly clothed with whitish 

 pile, except in the median line ; sides of the segments below 

 thinly clothed with short silvery pile ; genital ring a broad 

 quadrangular plate. 



Legs : coxce shining black, pollinose, clothed with whitish 

 pile, the posterior pair also with black hairs ; femora reddish 

 brown, pollinose, apices black, extreme tips shining, clothed 

 above and below with whitish pile, while the second and third 

 also bear a certain number of black hairs on the inner side at
