being the relatively larger head, smaller force])s and the reduced 

 antennal segmentation ; head broadly cordate, dark brown, eyes 

 black, antennae with eight joints, sparsely covered with short 

 stout hairs, and 2nd joint short, one-fourth the length of the 3rd, 

 which is the longest, 4th to 8th about equal, terminal joint coni- 

 cal, brown, the basal joints yellow, gradually darkening, the api- 

 cal dark brown. Pronotum subquadrate, narrower than head, 

 angles rounded, testaceous, posterior margin being slightly 

 emarginate. Mesonotum quadrate, equal in width and length 

 to the pronotum, angles rounded, testaceous, with a median pale 

 infu'scate transverse band which extends to the episterna. Me- 

 tanotum posteriorly slightly wider than the preceeding and 

 shorter, distinctly emarginate, yellowish brown. Abdomen, 

 campodeiform, dorsal segments ten, the ist visible; ventral 

 segments eight, no trace of 9th and loth visible, testaceous, the 

 sides with dark brown bands, widening and darkening antero- 

 posteriorly and uniting at about the 7th segment. Forceps 

 slender, nearly straight, no trace of segmentation, bases testa- 

 ceous, reddening apically ,with stout han-s sparsely distributed. 

 Legs stout, testaceous, basal halves of the femora smoky brown, 

 tarsus 3-jointed, second joint very short with a distinct lobe 

 which is about one-third the length of the 3rd joint.

Second Larval Iiisfar. 



At about the r)th day (after hatching) the ist ecdysis occurs. 

 The dimensions at this instar are as follows : 



Antennae 4 mm. 



Head and body 5-6 mm. 



Forceps 1.25 mm. 



The general facies is very similar to that of the previous in- 

 star ; the chief change being seen in the additional joints of the 

 antennae. The following variations from the previous instar 

 are to be observed : As regards the darkened areas, these are 

 much darker. Head blackish brown. Antennae with twelve 

 joints the additional four arising between the 3rd and 4th joints 

 from the segmentation of joint 3 ; the basal even testaceous ; the 

 newly formed 4th to 7th shorter than those succeeding them ; 

 8lh and 9th dark brown, loth (sometimes 9th or none) whitish ; 

 nth and 12th very dark brown, terminal conical. Pronotum 

 ciuadrate, as wide as head, yellow testaceous. Mesonotum, 

 blackish brown, except the posterior margin, which is testa-
