This is a minute species of CryptorJiTjuchus, and differs some- 

 what from the type of the genus — if we regard the Cr. Lapathi as 

 such — thougli not sufficiently, as it appears to me, to require 

 removal from that section. Its form is more elongated, and its 

 scutellum is so minute as to require the aid of a strong lens to 

 detect it ; the insect nevertheless has well developed wings : the 

 rostrum is stouter, and subdepressed, and is inserted in a very 

 deep rostral groove, which terminates between the coxse of the 

 anterior pair of legs ; the scape of the antennae is shorter and 

 stouter, the basal joint of the funiculus is also stouter, the second 

 joint is of an elongate obconic form, the remaining joints are also 

 obconic, but very short; the club is tolerably developed, and 

 of a short ovate form; the femora are rather less stout, and very 

 indistinctly toothed beneath. 



The head is covered chiefly with pale scales, but has two black 

 spots ; the thorax is rather broader than long, rather suddenly 

 contracted in width from the middle to the fore part, and with the 

 lateral margins of the hinder half nearly parallel, being very slightly 

 rounded ; the upper surface is densely beset with short, stiff", erect 

 bristles, which are most of them black, but some few are white, 

 and are aggregated in parts so as to form small spots and a white 

 mesial line; the hinder margin is clothed with orange-yellow scales, 

 and these form a small spot near the scutellum. The elytra are 

 more than three times the length of the thorax, and about half as 

 wide again, the humeral angle is rounded, the sides nearly parallel, 

 except towards the apex, where they are rather suddenly con- 

 tracted, and obtusely rounded : they are covered with scales, some 

 of which are dirty white, others brown, and others black, producing 

 a variegated appearance ; in each of the tolerably large punctures 

 of the striae is a white scale : on the fourth interstice from the su- 

 ture is a small white spot, which is rather more conspicuous than
