Phytophaga 31ulayana. 179 



of the front impressed with a longitudinal groove, which runs 

 upwards from the apex of the epistome ; the latter entirely sepa- 

 rated from the front, pentagonal, apical angle nearly rectangulai*, 

 apex acute ; sides straight, and very slightly converging back- 

 wards ; anterior border concave-emarginate, angles of the con- 

 cavity acute, slightly produced ; surface more coarsely punc- 

 tured than the front ; antennas and hibrum entirely black. Thorax 

 equal in breadth to the elytra ; sides rounded, converging in 

 front ; anterior angles obsolete, hinder angles tuberculate ; sur- 

 face deeply impressed with large round punctures. Scutel- 

 lum as broad at the base as long, semiovate ; sides converg- 

 ing backwards ; apex rounded. Elytra parallel, not excavated 

 below the basilar space ; striae strongly punctured in front, sub- 

 sulcate, the interspaces minutely but not closely punctured, 

 slightly but distinctly convex ; behind the middle the striae are 

 much less deeply punctured and very fine, and near the apex 

 the punctures are visible only under a lens ; on the hinder disk 

 the interspaces gradually flatten and become plane before their 

 termination. 



The shorter body, broadly dilated thorax, and entirely black 

 colour above, will at once distinguish this species from its con- 

 geners.

Subelongata, convexa, nigro-picea, nitida ; pedibus obscure 

 rufo-piceis; antennis basi rufo-fulvis; thorace sparse hie 

 illic sat profunde punctato ; elytris thorace latioribus, paral- 

 lelis, infra basin vix transversim excavatis; striis integris, 

 ante medium sat fortiter punctatis, leviter sulcatis ; inter-

 impressis, apicem versus fere deletis ; interspatiis fere planis ;

Head very finely granulose, finely punctured ; epistome entirely 

 separated from the front, pentagonal, scarcely longer than broad, 

 apical angle acute; sides straight and parallel in front, slightly 

 converging near the apex ; middle of anterior border deeply con- 

 cave-emarginate, angles of the emargination produced, obtuse; 

 surface deeply impressed with large punctures ; lower portion of the 

 front impressed with a deep groove, which runs upwards from the 

 epistome ; a broad line, running along the inner and upper margin 

 of the eye, together with the labrum, rufo-piceous ; anterior border
