short pubescence, tibi;e with a few long hairs, antennse with 

 blackish seta^ and rather long outstanding hairs. Head and pro- 

 thorax with large shallow punctures, almost concealed l:)y 

 pubescence; elytra seriate-punctate (in about ten rows), the 

 punctures large and coarse at base, becoming obliterated towards 

 apex; mesosternum densely and strongly punctate; metasternum 

 and abdominal segments densely and minutely punctate, the 

 former with large scattered punctures; legs very densely and 

 minutely punctate. 



Head truncate at base, about as long as the width across eyes; 

 eyes rather large, prominent and finely faceted; antenna? rather 

 stout, not quite reaching apex of metasternum, the distance 

 between their bases slightty less than between them and the apex 

 of mandibles, composed of tw-elve joints, 1st small, globular, dis- 

 tinctly separated from 2nd, 2nd larger, about the size of 7th, 3rd 

 narrowest, 3rd-llth subequal in length and increasing in width, 

 12th not quite as long as lOth-llth combined, its basal half about 

 the size and shape of 11th, decreasing then to apex. Prothorax 

 wider than, long, longer and slightly wider than head, strongly 

 constricted towards and truncate at base, apex transversely 

 globose; median canal distinct but shallow in the middle, obsolete 

 at base and apex. Scutellum triangular, considerably longer 

 than wide. Elytra parallel-sided to near apex, fully twice as long 

 as head and prothorax combined, about once and a half as 

 wide as the latter at base, base scarcely truncate, shoulders feebly 

 rounded; a feeble depression near the base (only visible when 

 viewed sideways). Margins of mesosternal keel finel}^ carinate. 

 Legs long, tibise almost straight. Length 51, width Ih mm.

May be distinguished from either L. cocciiiea or L. 2 faster si by 

 its much more elongate form, less, angular prothorax, longer 

 scutellum, longer pubescence, distinctly twelve- jointed antennae, 

 (fee; in both of those species the scutellum is tranvserse, in 

 Mastersi rounded, and in coccinea truncate at apex. Members of 

 this genus are subject to considerable alteration of colour if 

 immersed for any time in spirits, the head and prothorax
