without eburneous spots, and spinose at apices. Abdominal seg- 

 ments unequal in length. Mesosternum broad, obliquely declivous in 

 front, emarginate behind. Prosternal process not very narrow, and 

 arcuately declivous posteriorly. Anterior coxae large, subglobose, 

 moderately prominent, not angulated externally, and the cavities 

 open posteriorly. Intermediate coxal cavities open externally. 

 Legs unequal in length; tibiae not longitudinally carinate; femora 

 spinose at apices, feebly clavate, but not petiolate at bases ; posterior 

 tarsus with the first joint scarcely as long as the following two 

 joints united. Body not conspicuously pubescent. 



Genotype. — Brittonella chardoni, new species. 



This genus belongs to the tribe Hesperophanini and is allied to 

 Hesperophanes Mulsant, but it differs from that genus in having 

 the elytra spinose at apices, antennae not distinctly longer than the 

 body, and not ciliate beneath, pronotum not transverse, femora 

 spinose at apices, and the body only obsoletely pubescent. 



I take great pleasure in dedicating this genus to Dr. N. L. Britton, 

 eminent botanist, director for more than three decades of the New 

 York Botanical Garden, chairman of the Porto Rico committee of 

 the New York Academy of Sciences, to whose able and indefatigable 

 services are due in large part the success of the natural history 

 survey of Porto Rico. 



BRITTONELLA CHARDONI, new species 



Male. — Elongate, parallel, strongly flattened above, moderately 

 shining, uniformly reddish brown, with the legs and antennae more 

 yellowish brown. 



Head with the front very short, strongly transverse, uneven, 

 deeply, abruptly depressed between the antennal tubercles, which are 

 narrowly separated and slightly elevated, feebly, coarsely, irregularly 

 punctate, sparsely, irregularly clothed with erect, coarse, whitish 

 hairs, and with a narrow, longitudinal groove between the antennal 

 tubercles; eyes separated from each other on the top by about the 

 width of the upper lobe. Antenna about as long as the body, basal 

 joints sparsely clothed with long, erect hairs, apical joints densely 

 clothed with short, recumbent, whitish pubescence; first joint rather 

 robust, subcylindrical, feebly arcuate, slightly flattened beneath, 

 slightly longer than the third joint, which is two-thirds longer than 

 the fourth, the following joints subequal in length to the first. 



Pronotum as wide as long, slightly wider at base than at apex; 

 sides nearly parallel, rather strongly sinuate, more or less narrowed 

 toward apex, and narrowly constricted at base ; disk slightly uneven ; 

 surface more or less rugose, sparsely, coarsely, irregularly punctate, 

 and sparsely clothed with moderately long, erect, whitish hairs.
