Body pale yellowish: antennae Mackisli; tliiiT hasal j»jint« 

 honey-yellow, with a black line alxivo : vortex with a black spot 

 thorax with twn (<niall dotH, ainl an abbreviated lino arranged tri- 

 angularly, black, and a lateral, somewhat larger, oblitjue, oval, 

 indented black dot : (-•eutel black : elytra inipunctured, destitute 

 of strife ; a common sutural black vitta, another in the middle, 

 somewhat narrower than the intervening portion, and a subniar- 

 ginal one : pectus yellnwish : postpeetiiH and venter black, the 

 latter with yellowish margins to the segmeut*< : feet honey-yellow : 

 tibiae and anterior and intermediate thighs with a black line. 



liCngth one-iifth of an inch. 



Very closely allied to A. nltttuntit IHig , the form and propor- 

 portion of the elytral vitta being the same, but that species is 

 somewhat larger, and is altogether destitute of the lateral thora- 

 cic impressed dots. 



3. A. CKHACOr.Lls. — White ; head black, elytra violactH)us. 



Inhabits Mexico. 



Uody white, impnncturcd ; head black, with an elevated line 

 below the antennas: antennae black, second and third joints white, 

 with a black line above : thorax immaculate : elytra violaceous, 

 burnished j tarsi and tips of the tibiic black. 



Length less than one-fifth of an inch. 



Resembles the .1. roUaris Illig., (jrauthonohta Dalman,) but 

 is much more closely allied to .1. cnllat<t Fabr. It is somewhat 

 doubtful if it be a distinct species ; but as I pos^-^css specimens 

 of the latter from Pennsylvania, Missouri [201] and Florida, all 

 correspond in having green elytra, white front, and other dis- 

 tinguishing traits, I have ventured to assign it a distinct name. 



EKOTYLUS Fab.
