2. L. GUTTATA. — Elytra with minute elevated points, and 

 about sis obsolete gray spots. 



Lamia Q-guttata Melsh. Catal. 



Body brownish : antennae a little longer than the body, obscurij 

 rufous ; the joints dusky at their tips : thorax a little inequal, 

 with hardly elevated, very obtuse tubercles ; lateral spine none, 

 being substituted by a slightly elevated tubercle : elytra punc- 

 tured, each with six lines of minute black spots, which are each 

 elevated, reflected, and acute ; about six obsolete gray spots on 

 each, of which one is sub-marginal behind the humerus, a minute 

 one is upon the middle, and the third is small, subsutural, and 

 behind the middle : thighs clavate, blackish : tibias dull rufous, 

 annulate with dusky. 



Length nearly seven-twentieths of an inch. 



This species resembles the preceding, but it may be distin- 

 guished by the want of the large gray lateral spot of the elytra, 

 and more essentially by being armed with reflected points on the 

 elytra. It also resembles the L. acuJifera nobis, but is destitute 

 of the whitish elytral band, and the general form of the body is 

 diflFerent from either, being less robust,

Body light brownish-cinereous : antennae a little longer than 

 the body, with rather long, close-set hairs on the inferior side :
