70 GYRETES GLABRATUS. 



(Ier tliis species ; it only differs from scaphidiformis by the 

 somewhat smaller size (hardly 6 mm.) and by the tomen- 

 tous border of the elytra , which widens out very suddenly 

 in the middle, forming here a projection in the shape of 

 an obtuse angle, and attains the suture at a somewhat 

 larger distance from the apex. 



12. Gyretes glahratus, sp. n. 



Long. 5^/2 — 6 mm. — G. cincto Germ, simillimus. Ova- 

 tus, convexus, postice paululum atteuuatus, supra nitidis- 

 simus, nigro-coeruleus , plus minus iricolor, anguste luteo- 

 marginatus; subtus nigro-piceus , pectore medio, abdominis 

 apice pedibusque rufis , epipleuris flavis; prothorace anguste 

 ad latera punctato-tomentoso ; elytris ad apicem paulo obli- 

 que truncatis (9 magis oblique) , angulis rectis , haud de- 

 letis ; elytris angustissime utriuque a medio et ad trunca- 

 turam punctato-tomentosis. cf tibiis anticis angulo apicali 

 externo obtuso , vix deleto ; tarso dilatato , ovato. 



This species is closely allied to Gyretes cinctus Germ, but 

 differs from it by the following characteristics: the tomen- 

 tous border of the prothorax is a little narrower; that of 

 the elytra begins on the middle as a narrow edge which 

 posteriorly widens out inconspicuously and, accompanying 

 the contour of the outer edge and of the truncation , at- 

 tains the suture scarcely before the apex ; the outer apical 

 angle of the anterior tibia of the cf i^ obtuse and hardly 

 blunted , whereas it is strongly rounded in cinctus ; tarsus 

 likewise dilated and oval.
