what irregular, intervals flat, smooth. Metasternum coarsely punctured at 

 tlie sides, abdomen obsoletely punctate. Length .06 — .08 inch; 1.5 — 2 mm. 

 (PI. VII, fig. 10). 



Male. — Anterior and middle tarsi slightly stouter, posterior femur with the 

 outer condyle prolonged into an obtusely unciform process. Tarsi 5 — 5 — 4. 



Female. — Tarsi not broader. Posterior femur broad without unciform process. 

 Tarsi 5—4—4. 



Four specimens, Detroit, (Hubbard); District of Columbia, (Ulke). 



L.IODES Latr. 

 Head feebly convex, not narrowed behind, received in the emarginate thorax 

 nearly as far as the eyes, beneath with well defined antennal grooves, oblique 

 from the eyes inward. Clypeus slightly jjrolonged beyond the front and 

 corneous, separated from the front by a well marked impressed suture and :» 

 depression on each side. Eyes round, moderately prominent. Labrum short 

 usually truncate in front. Mandibles robust, not prominent, simple. Maxillary 

 palpi slender at base, the terminal joint stout, conical. Antennse arising under 

 a slight frontal margin, nearly attaining the hind angles of the thorax, eleven- 

 jointed, first joint stout, second nearly as stout but shorter, third slender and 

 longer, 4 — 6 small, gradually broader, the next five forming an elongate loose 

 club, the second joint of which is smaller. Anterior coxfe closed behind, the 

 presternum in front very narrow. Mesosternum moderately separating the 

 middle coxse and usually nearly vertical between them, not carinate. Posterior 

 coxse contiguous. Abdomen with six segments, the terminal usually small. 

 Legs not long, the tibise spinulose externally. Tarsi slender, the first joint of 

 the posterior moderately long, the number of joints variable in the sexes, being 

 5—5—4 in the male and 5 — 4—4 female. 



I am indebted to Dr. Leconte for the use of a short tabular study 

 of the species of the present genus, prepared by Mr. Frederick 

 Blanehard of Lowell, Massachusetts, in which I find the species well 

 and accurately separated, but the increase in the mass of material 

 before me required the preparation of an entirely new table which is 

 presented below. The characters there used seem sufficiently definite 

 and not to need further explanation. 



Elytra with regular striae of punctures 1. 



Elytra with more or less confused striae, becoming in some species nearly 

 double striae 2. 



Elytra without strial arrangement, punctures confused 3. 



1, Ninth stria of punctures marginal in the greater part of its length, distant 



from the margin at base only. 

 Elytra strongly sinuate at the sides, the ninth stria very distant from 

 margin at base, punctures of striae rather fine. 



Intervals of strias distinctly punctulate globosa Lee. 



Intervals of striae smooth or very nearly so polita Lee. 



Elytra not sinuate at the sides, the ninth stria not very distant at base, 



punctures of striae rather coarse, intervals smooth discolor Mels. 



Ninth stria distant from the margin in its entire length, elytra not sinuate. 



Bluiichardi n. sp.
