The Sf"! and 4* joints of the antennae are equal, and a little shorter than the 5"i. 

 Varies with the elytra fuscous. I have diligently compared this with European spec- 

 imens, without finding any difference. 



*2 Anthophilax. Caput mox pone oculos constrictum, palpis dilatatis, labialibus 

 multo latioribus. Antennae ll-articulatse,^ inter oculos insertse ; oculi emarginati. 

 Thorax angulis posticis rectis, utrinque modice constrietus, lateribus acute tubercu- 

 latis. 



To this group belongs Pachyta 4-maculata of Europe. Differs from Strangalia and 

 Leptura by the dilated labial palpi. 



A. viridis. — Nigra, capite thoraceque virescentibus, punctatis, cinereo-pubescenti- 

 bus, hoc antice angustato, utrinque constricto, leviter canaliculato, lateribus subacute 

 spinoso, elytris grosse confluenter punctatis, substriatis, splendide viridi-ajneis, apice 

 rotundata, antennis apice, tibiis basi rufescentibus. Long. ■&. Eagle Harbor. 



The S^*! joint of the antennae is longer than the 4'^. 



*^ S. plebeja. — Elongata, nigra, confertim punctata, thorace longe flavo-pubescente 

 lateribus parum rotundatis, utrinque tenuiter profunde constricto, angulis posticis 

 laminatim productis ; elytris testaceis, postice sensim angustatis, paulo dehiscentibus, 

 apice intus incisa. Long. -55. 



Precisely similar to S. nigrella, except in the color of the elytra: the pubescence of 

 the thorax is long and prostrate ; while in S. nigrella it is short and erect. 



■•■* L. tibialis. — Nigra, brevitcr flavo-pubescens, capite thoraceque confertissime 

 punctatis, hoc convexo, antice parum angustato, apice, basique constricto, lateribus vix 

 rotundato, elytris confertim punctatis, subparallelis, apice paulo dehiscentibus, intror- 

 sum oblique leviter truncatis, flavo-testaceis, macula lateral! ad medium, altera majore 

 pone medium, apiceque nigris, tibiis tarsisque flavis, illis apice fuscis. Long. -43.
