400 ANNALS OF THE LYCEUM. 



25. E. INSIPIENS. — Briglit reddish-brown; transverse fronta 

 line much elevated, rounded. 



Desc. Body rather slender, bright reddish-brown, polished : 

 head with the transverse line prominent, regularly rounded, the 

 edge acute ; antennge a little serrate, second and third joints sub- 

 equal : thorax with an obsolete impressed line at base : elytra 

 with impressed punctured striae. 



Length more than one-fifth of an inch. 



[A species of Cr atony ckus. — Leg.] 



26. E. APPRESSiFRONS. — Obsoletely metallic ; transverse fron- 

 tal line not prominent. 



Desc. Body rather slender, dark brownish, with a slight brassy 

 tinge ; hairs recurved, not prominent : head with the frontal line 

 or tip of the clypeus not elevated, but decurved between the an- 

 tenna; : antennae rather robust, serrate ; second joint much 

 shorter than the third, which is of the same form, and nearly of 

 the same size as the fourth ; terminal joint abruptly contracted 

 near the tip ; thorax with an impressed longitudinal line obsolete 

 before : elytra with acute, punctured striae, suture exterior mar- 

 gin somewhat paler : feet piceous : abdomen margined with dull 

 rufous. 



Length two-fifths of an inch. 



Rather common. It closely resembles cylindriformis nob. : but 

 that insect is somewhat larger, with a prominent, emargined 

 [268] frontal line, the third joint of the antennae is cylindrical, 

 altogether different in form from the fourth, and the ultimate 

 joint is not abruptly contracted near the tip; in these and many 

 other characters it obviously diff"ers from the present species. 

 In soine specimens the anterior margin of the thorax is obscurely 

 piceous. 



[Belongs to Corymhites. — Leg.] 



27. E. COLLARIS. — Black ; thorax rufous ; frontal line not re- 

 fleeted; second and third joinis of the antennas subequal. 



Elater collaris Melsh. Catal. 



Desc. Head black, the frontal transverse line or tip of the cly- 

 peus not in the slightest degree reflected, but considerably ele- 

 vated above the surface of the nasus : antennae serrate, second and 

 third joints subequal and nearly alike in form ; thorax bright 

 rufous, posterior spines acute : scutel black, orbicular : elytra
