KEVISION OF ELEODIINI BLAISDELL. 305 



together scarcel}^ as long as the fourth; first joint with a total length 

 of about twice as long as wide. 



The ungues are comparatively long. 



ELEODES VENTRICOSA var. FALLI, new. 



Elongate-ovate, .smooth and shining, elytra scarcely inflated, simply 

 jjunctate and more or less caudate in the male. 



Antennm as in ventricosa. 



Prothorax quadrate, about one-eighth wider than long, not notice- 

 ably more narrowed anteriorly than posteriorly; apex broadly and 

 quite strongly emarginate ; sales evenly and quite moderately arcuate 

 from base to apex; base one-fifth to one-fourth wider than the apex 

 and more or less greater than the length; apical angles strongly 

 prominent anteriorly, acute, rather large, slightly reflexed and not 

 everted ; basal angles obtuse and not rounded. 



Propleurce quite smooth and quite obsoletely sculptured. 



Elytra rather broadly oval, scarcely inflated, sides evenly and 

 moderately arcuate, w4th the apex more or less produced ; disc quite 

 evenly arcuate from side to side, sometimes slightly depressed on the 

 dorsum, not sulcate, punctate, punctures fine and usually of the same 

 size; the serial punctures may be coarser, scarcely more strongly 

 sculptured laterally. Cauda feebly impressed along the suture and a 

 little longer than in rentricosa. 



Sterna and parapleuraj more or less obsoletely sculptured and 

 glabrous. 



Legs usuall}^ rather slender; anterior tibiae slightly constricted at 

 base, otherwise as in ventricosa. 



Male. — Body somew^hat robust. Elytral cauda about 4 nnn. long 

 and less oblique than in rentricosa. The tuft of spinules on the first 

 joint of the anterior tarsi is interrupted at middle and does not close 

 the groove. Otherwise as in centricosa. 



Female. — Body moderately robust. Elytral apex more or less 

 slightly produced and subacute. Otherwise as in rentricosa. 



Measurements — Male: Length, 32.2 mm. with cauda; width, 12.5 

 mm. Females: Length, 30-33 mm.; width, 13.2-14 nnn. 



Genital charactei's, imde. — As in rentricosa. 



Female. — Compares with rentricosa as follows: The genital seg- 

 ment has the apical margin of the dorsal plate of a valve less oblique 

 and sometimes feebly arcuate; angle about as or less prominent. 



The ventrolateral surfaces are less strongly but more evenly convex, 

 and the surface lines straight when viewed longitudinally. 



The appendage is larger, subconico-semiellipsoidal, completely fill- 

 ing the fossa and projecting beyond the margins of the dorsal, plate, 

 not as long as wide.
