'E^TOMOhOGY .—Description of a new species of Sphenophorus 

 from Florida (Coleoptera) . F. H. Chittenden, Bureau of 

 Entomology.^ 

 Recently, during studies of the weevils of the genus Spheno- 

 phorus, an undescribed species collected in Florida by Hubbard 

 and Schwarz has come to my attention. This may be known 

 from the following brief description: 



Sphenophorus deficiens Chittenden, sp. nov. 



Body more than twice as long as wide. General color black, mod- 

 erately shining. Head finely, sparsely, punctulate. Rostrum half as 

 long as thorax, feebly arcuate, rather wide, moderately, nearly equally 

 compressed, this compression more pronounced at the base; base much 

 widened but not dilated in front of scrobes, flattened, not sulcate, 

 interocular impression shallow, foveate; apex feebly dilated; surface 

 finely not deeply punctulate, at base moderately punctate, punctures 

 shallow and sparse. Thorax one-fourth longer than wide, posterior 

 half with nearly parallel sides, very little narrower at base, anterior 

 half narrowing toward apex, which is very feebly constricted at sides and 

 scarcely above; surface coarsely irregularly punctate, punctures 

 finest and sparsest just in front of middle where there is a short, nearly 

 smooth, but scarcely elevated space representing the median vitta; 

 a little coarser each side of the middle on the posterior half in what 

 corresponds to the lateral vittae; the surface between these vittae 

 very coarsely irregularly foveate-punctate, some of the punctures 

 contiguous and some confluent ; a shallow fossa each side of the vittae 

 there caused by the coarse punctures coalescing at these points. Elytra 

 one-fifth longer than thorax, subovate, at base distinctly margined, at 

 humeri broadly rounded, gradually narrower toward apex; surface 

 uneven, distinctly finely striate, striae interrupted by large, rounded, 

 moderately deep punctures; intervals flat, of unequal width, but not
