DESCRIPTIONS OF NEW SPEC1KS. 113 



peculiar; small scattered granules arc visible, equally distributed ; 

 the rest of the surface is nearly smooth at the base, bul gradually 

 becomes granulated, until at the tip the granules arc quite dis- 

 tinct, though the difference between them and the larger scattered 

 granules is quite obvious. The bod; beneath is nearly smooth 

 with a few long yellow hairs near the edge of the prothoras 

 and on the epipleura?; a few wrinkles are also Been Dear the 

 anterior coxas. 



This species indicates a different section of the genus from anj 

 heretofore described. 



The singular arrangement of the epipleura! limits in (lie differ- 

 ent sections of this genus seems to demonstrate the necessity of 

 uniting the Praocini with the Coniontini. In this case the tribe 

 Branchini should be suppressed, unless the short gular fissure is 

 sufficient to separate it. 



3S2. Ell. laevis. Ovalis convexus, uiger subopacus, imptractatns, 



thorace angulis posticis retrorsum productis ; elytris abasi ultra medium 

 paulo ampliatis, et lateribus fere rectis. Long. •5ti ; lat. *32. 



Cape San Lucas, Lower California; Mr. Xantus. Less rounded 

 in outline than Eu. reticulalus, with the sides of the elytra almost 

 straight from the base to beyond the middle, and nearly parallel, 

 though very slightly wider behind. The upper surface is dull 

 and entirely without sculpture; the under surface is also dull, 

 and marked with only a few wrinkles on the under part of the 

 prothorax near the coxae. The elytra are suddenly declivous at 

 the sides, not margined as in Eu. reticulalus, but the epipleura;, 

 as in that species, are well defined, and suddenly dilated at the 

 base. It therefore indicates a separate section of the genu- inter- 

 mediate between Discodemus and typical Eusattus. The anterior 

 tibiae are obliquely prolonged at the outer angle, which is rounded 

 at the tip. 



CONICKVTIS Esgii. 



383. C. lata. Ovalis robusta convexa, piceo-uigra, rabopaea, capita 

 thorace elytrisque aqualiter punctulatis, thorace latitudine duplo br.-vi- 

 ore, a basi antrorsum fortiter angustato, lateribus rotundatis, angoltl 

 posticis magis productis; subtus nitida punctulata, prothoraoe renal 



coxas longitudinaliter rugnso, antennis pedibusque piceis. Long. -4G ; 

 lat. -24— long. -40 ; lat. -20.
