334 Coleopterological Notices, V. 



Besides these two species, the genus will probably include Homa- 

 lota geniculata Mixkl., specimens of which, or of an extremely closely 

 allied form, I have taken abundantly at San Francisco and San 

 Diego; it probably follows the general rule, as observed in Mots- 

 chulskium sinuatocolle, Aleochara sulcicollis and several other 

 well-known species, and extends along the entire coast from Alaska 

 to Lower California. This distribution of sea-beach species is 

 exactly what might be expected, as the cold inshore current from 

 the north maintains the water at practically the same temperature 

 throughout. I am at a loss to understand the reference of genicu- 

 lata to Eudera Fvl. in our most recently published check-list; it 

 does not remotely resemble the representatives of that genus, which 

 are related closely to Falagria. 



EIJRYPROIVOTA n. gen. * 



Body rather broad, convex. Head moderately inserted, the nuchal 

 constriction concealed; eyes moderate, not prominent, at more than 

 their own length from the base, the tempora parallel, nearly straight; 

 labrum short, transverse, truncate. Antennae inserted in small foveae 

 at a noticeable distance from the eye, feebly incrassate, the basal 

 joint compressed; second and third subequal, the latter obconical, 

 more than twice as long as wide ; tenth about as long as wide ; 

 eleventh conoidal, as long as the preceding two. Maxillary palpi 

 moderate, the third joint much longer than the second; fourth 

 oblique, slender, one-half as long as the third. Ligula with a 

 slender apical process forked at apex, the labial palpi apparently 

 three-jointed, with the third joint long and slender. Infralateral 

 carina obsolete. Mentum trapezoidal, the apex feebly emarginate. 

 Prothorax very large, transversely orbicular, the hind angles very 

 broadly rounded ; hypomera strongly inflexed, not visible from the 

 side. Elytra moderate, much narrower than the prothorax. Abdo- 

 men with the basal segment alone impressed ; second longer than 

 the first or third ; fifth longer than the fourth. Mesosternal pro- 

 cess acute, extending slightly beyond the middle of the coxiB, the 

 latter contiguous, with the acetabula apparently shallow and ill- 

 defined. Metasternum ample ; the episterna parallel; epimera not 

 extending beyond the elytra, moderate, the suture almost obsolete, 

 disappearing under the elytra behind the middle. Legs short; tibiae 

 moderate, pubescent ; tarsi short, 4-5-5-jointed, the basal joint of
