SYNOPSIS OF THE LAMIIX/E. 127 



"Black, pubescence cinereous, dense and short, not intermixed with hairs: 

 thoracic surface a little inequal, sparsely punctured, variegated : elytra si)arsely 

 punctured, with black granulations, a few asjierities, a black sublateral vitta ex- 

 tending from the base beyond the middle." — LeConte. 



LrEPTUR^JES Bates. 



In tliis (^'C'luis tlie sides of the thorax are angulate close to the base ; 

 the aiitennie are scarcely finil)riate beneath, the j)ro- and inesosternuin 

 linear scarcely .se])arating the coxie, the first joint of the posterioi- 

 tarsi is as long as the others united. The following analytical table 

 is that of Dr. Horn (Tr. Am. Ent. Soc. vii, 126), suitably modified : 



Lateral prominence of the thorax rather broad and very close to the base. 



Kyininetricus. 

 Lateral prominence more slender and acute, the tip recurved, less close to base. 



Elytra lineate, eyes prominent megalops. 



Elytra fasciate. 

 The fascia behind the middle incomplete, broadly interrui)ted by the suture. 



signaliis. 

 The fascia broad, black and entire, oblique on each elytron, apex not lilack. 



querci. 



The fascia broad, black and entire, transverse, the apex also black. lacetiis. 



Elytra cinereous, each maculate with six round black spots; thorax with four 



spots regularise.

[The synonymy is less from differences in taxonomy than from 

 color ornamentations; pictuii, the form most commonly met with is 

 pale, with short gray pubescence; four spots on the i,horax, two spots 

 on each elytron near to the base and clo.se to the suture, a lateral 

 stripe before middle connected with a broad, irregular, transverse 

 band seldom attaining the suture, and three spots in front of apex 

 arranged in the arc of a circle often united, black. From this these 

 markings vary in both directions, .so as to liecome nearly suffused or 

 entirely wanting, as in ut,onuitn.'<.1 " Ham." 



Li. iiiegalops n. sp. 



[Elongate, narrow, i)arallel, piceous black throughout, shining with dull luster, 

 l)ubescence cinereous, very fine, short and incons])icuous above, longer on the ab- 

 domen, two obscure, narrow, interrupted lines of grayish or reddish pubescence 

 on the disc of each elytron. Head smooth, minutely jiunctrtte; front convex,
