DESCRIPTIONS OP NEW SPECIES. 133 



rugous ; the side-pieces of the trunk are densely punctured, and 

 the abdomen is more finely punctured and more shining; the pro- 

 sternum is densely, and the metasternum sparsely punctured. 



The slightly undulated outline of the sides of the thorax will 

 enable this species to be easily recognized.

A mutilated specimen from California, kindly given me by Mr. 

 J. Akhurst. The form is as elongated as H. gracilis, but the 

 elytra are marked with transverse rugosities as in H. rugulosus 

 and opacus. The antennae are more than half the length of the 

 body, not very Slender, and the 9th and 10th joints are about 

 twice as long as their width. 

 



415. H. Slllcipennis. Apterus, modice elongatus, nigro-seneus 

 nitidus, viridi variegatus, capite thoraceque fortiter dense puuctatis hoc 

 latitudine haud breviore, lateribus late rotundatis tenuiter marginatis, 

 modice convexo, apice truncato angulis haud rotundatis, basi late rotun- 

 data tenuiter marginata, angulis posticis subrectis ; elytris ovalibus 

 thorace latioribus, striis profundis externis punctatis, interstitiis con- 

 vexis vix punctulatis ; prothorace subtus plicato-punctato, metathorace 

 rude, abdomine subtilius punctato ; antennis Cmaris) elongatis, gracili- 

 bus, extrorsum parum incrassatis. Long. -30. 



One specimen found by me on Mount Yona, Habersham Co., 

 Georgia. Three joints of the front and middle tarsi are moder- 

 ately dilated and spongy beneath. The 9th and 10th joints of 

 the antennae are longer than twice their width. The elytra are 

 as deeply striate as in H. venustus. 



416. H. mgicollis. Apterus, elongatus, seneo-piceus, subnitidus. 

 capite thoraceque confertissime longitudinaliter aciculatis, hoc sub- 

 quadrato latudine paulo breviore, transversim parum convexo, apice 

 basique fere truncato, angulis anticis fere rotundatis, lateribus late 

 rotuudatis, angulis posticis obtusis subrotundatis ; elytris oblongis,
