BEETLES RELATED TO PHYLLOPHAGA—SAYLOR 159 
described ones known to me that belong in Triodonyx. P. ecostata 
possesses most of the characters of the new genus (3-toothed tarsal 
claws, lack of noticeable sexual differences, incomplete tibial carinae, 
straight clypeal carina) except that the propygidium is plane and not 
sulcate; in spite of this I believe it best to place ecostata, at least for 
the time being, with Jalanza and gigantissima. 
CNEMARACHIS,’ new genus 
Adults with characters on the whole as in PAhyllophaga, sensu stricto, 
but differing as follows: Either middle or hind tibiae or usually both, 
of both sexes, with an incomplete carina; lateral margins of the middle 
and hind tibiae usually with obviously serrate edges or with one to 
several moderately large to large spines; only rarely do the tibiae 
lack such carinae or spines or teeth. Locality : West Indies. 
Genotype.—Lachnosterna vandineit Smyth. 
The genus includes nearly all the described West Indian species 
formerly placed in Phyllophaga. 'These have at one time or another 
been listed under the following generic names: Ancylonycha Dejean, 
Phyllophaga Harris, Lachnosterna Hope, Melolontha Fabricius, and 
Phytalus Erichson. The genus is divided into the following two 
subgenera: 
CNEMARACHIS, sensu stricto, new subgenus 
Tarsal claws in both sexes with a distinct median or submedian 
tooth. Tibia never with a complete or nearly complete carina. 
Type of subgenus.—Lachnosterna vandinei Smyth, from Puerto 
Rico. Nearly all the described species of Cnemarachis belong in this 
subgenus. In most of them the lateral tibial teeth are very marked, 
the antennal club is small and ovate, and the male abdomen is rather 
gibbose, much as in the females of the continental Phyllophaga. - 
ABCRANA, new subgenus 
Tarsal claws entirely simple in the male (female unknown). Hind 
tibia with a weak, though nearly complete, carina. Middle tibia with 
carina usually complete, at times much feebler at the middle than 
at sides. 
Type of subgenus.—Phyllophaga crinitissima More, monobasic. It 
occurs in Puerto Rico. 
CLEMORA, new genus 
The adults are similar to those of the genus Phyllophaga but differ 
from them in the following characters: Hind and middle tibiae each 
with very incomplete carina; lateral tibial edges with spines; and 
3 enema, tibia + rachis, spine.
