adjoining surface scarcely fit all raodified. The female difters 

 somewhat, having the thoracic process slightly wider and just 

 noticeabl3' narrowed at base, the elytra barely twice as long as 

 wide and very broadly and obtusely rounded behind, and the 

 elytral maculation paler and more suffused. In some of its 

 characters pictus recalls sem'atus, the anterior fascia being a 

 coalescent variation of the short dashes of that species, but the 

 elongate, parallel elytra and non-dentellate thoracic process will 

 always readily- distinguish it. It is difficult to understand how 

 such a conspicuous form as this could so long have been over- 

 looked ; it is represented in my cabinet by five individuals. 



MECYNOTARSUS Laf. 



The differences between this genus and Notoxus are very radi- 

 cal, in spite of the general similarity of facies and possession of 

 the pronotal process, which is so eminently characteristic of the 

 latter ; in Mecynotarsus it is even more elaborately developed 

 than in Notoxus. But in Mecynotarsus the tarsi are extremely 

 long and filiform, with the penultimate joint cylindrical and un- 

 modified. The body is always small and of elegant form, and the 

 upper surface is devoid of the erect tactile setje so evident in 

 Notoxus. Our species may be known by the following charac- 

 ters, elegans differing almost subgenericallj^ from the fii'st three : — 



Upper surface clotlied with fine sericeous pubescence; eyes large; antennae 

 very slender; thoracic horn finely and closely crenulate. 

 Elytra devoid of median darker area. Atlantic Coast. 



Prothorax broadly rounded throughout at the sides, widest scarcely behind 

 the middle; elytra very nearly twice as long as wide. Length 2.0 mm. 



candid IIS Lee. 

 Prothorax widest and prominently rounded at the sides behind the mid- 

 dle; elytra three-fourths longer than wide flavicans n. sp. 



Elytra pale testaceous, with a conunon sutural piceous cloud. Yuma, Cal. 



Length 2.5 mm delicatlllus Horn 



Upper surface clothed with elongate parallel and decumbent scales, which are 

 white on the elytra, with a conspicuous pattern of black; eyes small; legs 

 and antenna; much shorter and stouter; thoracic horn less broad, with large 

 distant, abrupt and quadrate marginal teeth elegans Lee. 



The first two species and probabl}^ also the third, have the pro- 

 notum finely, deeply channeled along the posterior margin, the 

 surface thence rai)idl3' ascending to the general level and bearing
