which arc grey ; prothorax with a broad, dark brown, median 

 stripe, a less (listinct one on each side of it, and a narrower 

 one on the iiiMoxed sides; elytra M'ith the suture narrowly 

 Ight brown, and with dark l)rown niacuhir stripes covering; 

 stria; 1, 2, 5, an 1 the base of l-. But some or all of these 

 niarkiui^s may be very nearly obliterated. 



Also very close structurally to L. cana, but the eyes arc 

 decidedly more convex, and the central stria on tlie forehead 

 is more concealed by the scaling; the rostruin is even 

 shorter in proportion to its ba«:al width, and the central 

 carina is more raised at its baso ; the seta; on the head and 

 rostrum arc longer and distinctly raised, whereas in L. cana 

 they lie (juite flat; the setae on the pronotum and elytra are 

 similarly longer and much more conspicuous; the prothorax 

 lias the ba-*al margin narrowly carinate and less stiougly 

 rounded ; the scutcllum is smaller, being scarcely per- 

 ceptible ; the elytra bear very shallow striaj (of which there 

 is no trace in the other two species), and when abraded the 

 punciures appear appreciably larger and more closely set. 

 Length 5-6 mm., breadth 3-3.f mm.

Head twice as broad as long, trisculate, the eyes \ery 

 prominent. Rostrum subijuadrate, separated from the head 

 by a deep sinuous furrow that reaches the sides, the lower 

 surface with two dee[) longitudinal furrows and a transverse 

 basal impression ; epistome well defined, the sides forming 

 an obtuse ridge, rounded behind, the front margin deeply 

 sinuate and shorter than one of the sides ; mandibles multi- 

 setose and without scaliui:-, with a distinct median tooth and 

 a sharp longitudinal caiina running from the scar to the 

 base ; mentiim with the anterior part convex and bearing a 

 fringe of setae, the posterior part tlat and deeply sunk in 

 its cavity; serobes entirely lateral and quite invisible from 

 above, very deep and gradually widening outwardly, the 

 u[)per edge ending on a level with tie lower margin of the 

 eye. Antenna with the scape gradually clav;ite aiul rcachin--
