and by the longitudinal white lines behind the transverse one. 



Dark brown , the palpi , antennae and legs reddish 

 brown; covered with a delicate greyish pile and variegated 

 above with white lines and dots. The two basal joints of 

 the antennae entirely.^ the following joints only on the 

 basal half, covered with a fine grey pubescence; the legs 

 are covered with a similar pubescence which is intermixed 

 with a few erect pale coloured hairs; the antennae are 

 thinly fringed underneath with long pale coloured hairs 

 which disappear, however, towards the tip. 



The lower half of the head (the epistomum , labrum and 

 base of mandibles inclusive) covered with a dense pale 

 yellowish pubescence which is interrupted by several bare 

 lines , namely a transverse one separating the face from the 

 epistomum , an oblique one across the cheeks , three ver- 

 tical straight' ones (one along the middle of the face and, 

 on each side of it, another uniting the inner margin of 

 the eyes with that of the corresponding mandible) , and 

 finally a J-shaped one between the mesial- and lateral 

 lines. The vertex of the head with two diverging white 

 lines and another behind the eyes , all corresponding with 

 four similar lines on the pronotum of which the outer ones , 

 however, are more or less obliterated. 



The pronotum is irregularly wrinkled , and with an irregu- 

 lar smooth space in the middle; the wrinkles are inter- 

 mixed with a few glossy granules , especially on the flanks. 

 The scutellum is impunctate , transverse , broadly rounded 

 posteriorly. 



The elytra distantly covered with large and deep punc- 

 tures , whereas a few glossy granules are present at the base ; 

 they are divided , just before the middle , by a slightly 

 angular transverse line of a white pubescence; their basal 

 half is sparingly speckled with white , their apical half 

 surrounded by a narrow line of a white pubescence and 

 provided along the disk with three irregular similar lines 

 and a few white dots between them. 



The sterna are glossy and impunctate and show along
