No. 2370. BEETLES OF THE TRIBE TILLINI—WOLCOTT. 283 



basal half, becoming finer posteriorly and obsolete at apical fourth, 

 punctures separated by about half their own diameter; intervals 

 flat, as wide or nearly as wide as the punctures, finely, irregularly, 

 sparsely punctulate. Body beneath very finely, sparsely pubescent; 

 mesosternum coarsely, not closely punctate; metasternum with a 

 few moderately coarse, scattered punctures; abdomen with segments 

 one to four coarsely punctate, closely at the sides, more sparsely at 

 middle of first and second and finely and densely at middle of third 

 and fourth segments, the fifth segment in its entire width finely and 

 densely punctate. Legs moderately sparsely clothed with short 

 fine yellowish pubescence. Length, 9.25-13.25 mm. 



Male. — Fifth ventral segment parabolically emarginate; sixth 

 ventral wider than long, the sides strongly sinuate, narrower at base 

 than at apex, apex subtruncate, with a broad, deep U-shaped emargi- 

 nation, each apical angle of which is furnished with a long, dorsally 

 reflexed tooth, middle deeply sulcate from emargination nearly to 

 base. Last dorsal narrower but much longer than last ventral, sides 

 subparallel but feebly sinuate, apex strongly sinuate, with a narrow 

 but deep triangular emargination. 



Female. — As in balteata. 



Type locality. — North Carolina. 



Three paratypes.— Cat. No. 23126, U.S.N.M. 



Described from four specimens. The type, a male, from North 

 Carolina (B. Gerhard), in my collection, No. 60; paratypes, a male 

 from St. Louis, Missouri, May 11 (H. Soltau); a male from central 

 Missouri, July (C. V. Riley) ; a female from Laredo, Texas, May 28 

 (E. A. Schwarz). 



This species simulates balteata so closely that no doubt it stands in 

 many collections as that species ; it differs from that species by having 

 the body fully winged and the elytra proportionately broader at base; 

 the sexual characters of the male are also quite unlike those of balteata. 

 The female is only separable by the fact that the wings are not 

 aborted. 



CYMATODERA, species. 



Two females, one (No. 68) in my collection from Mississippi (R. J. 

 Weith) and one in museum collection from Crescent City, Florida, 

 are similar to the female of the preceding species, but differ somewhat 

 in abdominal sexual characters; while these very probably represent 

 a new species, I think it best to wait until male specimens of the form 

 are at hand before publishing a description of this species. 



CYMATODERA BALTEATA LeConte. 



Brownsville, Texas, June 27 (C. H. T. Townsend); LaGrange, 

 Texas, August 17 (E. A. Schwarz); Columbus, Texas, June 2 (E. A. 

 Schwarz); San Antonio, June 23 (H. Soltau); Texas (J. B. Smith). 

 Three males; five females.
