species having short beaks in both sexes are numerous within 

 the borders of the United States and have only been super- 

 ficially elaborated thus far." In the paper cited 9 additional 

 species are described. The present paper describes 5, and it 

 seems probable, as surmised by Colonel Casey, that there are 

 still more awaiting description ; in fact, it was only for lack 

 of sufficient material that some of the forms mentioned in the 

 present paper were not described earlier. 



Balaninus baculi, n. sp. (fig. 3). 



Elongate ovate, strongly convex above, brownish piceous ; head, ros- 

 trum, antennae, and legs piceo-rufous. Vestiture scant; of lower surface 

 and legs, composed of short pale-gray scales ; of elytra, the same, with 

 many small, moderately dull brown, inconspicuous scaly areas. 



Head about one-half as wide as thorax, eyes separated by three- 

 fourths their width, space divided by an impressed line terminating in 

 a rounded puncture posteriorly. Rostrum $ a little less than three- 

 fifths as long as the body, robust, 

 of nearly uniform width, slightly 

 widened at extreme base and apex, 

 impunctate, nearly straight to an- 

 terior fourth or third, where it 

 is more or less abruptly recurved; 

 antennae inserted just behind 

 proximal third. Scape scarcely 

 longer than first two funicular 

 joints, first funicular a little 

 shorter than second and third 

 together, third scarcely shorter 

 than second. Thorax one-fourth 

 wider than long; sides strongly 

 sinuous to apex, which is tubulate 

 and emarginate; base subtruncate; 



FIG. 3. Balaninus baculi: a, Female 

 beetle; b, head, rostrum, and antenna 

 of typical female; d, head and rostrum 

 of male; c, female of straight-beaked 



form. Four times natural size. (Orig- disk moderately convex, densely, 

 inal, U. S. Dept. Agr.) deeply and finely, and reticulately 



punctate. Elytra about one- 

 half longer than wide, nearly three times as long as, and less than 

 three-fifths wider than thorax; strongly rounded at humeri, sides arcu- 

 ate, rapidly convergent to apex. Striae somewhat narrow and deep, 

 with a single row of short white scales, with spaces between about 

 equal to their own length. Intervals wide, moderately convex, rather 

 finely and densely punctato-rugose. Scutellum nearly white, divided or 

 entire. Lower surface with scaly covering sparse, scales mainly very 

 short and whitish gray; fifth ventral segment deeply and widely concave 

 at middle, with sides more than usually arcuate and rounded. Femora 

 comparatively slender, teeth small, acute, with reentrant angle weak 

 and rounded. Tibiae slender, sinuous.
