Cryptocephalus iniplaciduSf new species 



Figures 3, 104 



General: Body 1.65 to 1.75 times as long as wide; dorsal surface 

 somewhat shining, mthout pubescence, most of ventral surface with 

 short, sparse, whitish pubescence. 



Head: Dull orange to light dull orange, vertex and antennal 

 insertions reddish or darker; front with large, coarse, dense punctures; 

 clypeus sharply delimited at sides, distinctly broadest at apex; 

 antennae of female a little over half as long as body, dull orange 

 throughout to brownish apically. 



Pronotum: Dull light orange to dull reddish orange, large punctures 

 irregularly darker or reddish; punctation dual, smaller punctures 

 minute, moderate in density, larger punctures large, dense, coarse. 



Elytra: Dull hght orange to dull reddish orange with vague indica- 

 tions of two dark, transverse bands, one behind middle, one before 

 apex. Each elytron with nine rows of fairly large, close punctures, 

 sometimes occasional punctures out of alignment or rows slightly 

 irregular; sixth and seventh rows even throughout to somewhat con- 

 fused; punctures slightly smaller at apex; inner and outer rows con- 

 fused at apex and not joining, confused punctures at apex obliterating 

 intervals. 



Ventral surface: Ventral surface and appendages dull reddish, 

 generally with femora, mesosternum, and base of abdomen dull orange. 

 Anterior margin of prosternum in female somewhat produced ventrally 

 into a rather broad lobe. Fifth abdominal segment at center with a 

 broad, deep pit in female. Pygidium dull orange to dull reddish, densely, 

 coarsely punctate. 



Length: 4.6 to 5.1 mm. 



Type data. — The above description is from three individuals, all 

 females. The holotype (USNM type number 69250) was taken at 

 Mansura, Louisiana, on March 26, 1910, by Cush (sic) and Hood. 

 One para type was collected at Hockley, Texas, on June 16, 1891, by 

 F. W. Thurow (in USNM). The final paratype is from Leon County, 

 Texas and was taken on May 18, 1948, by D. J. Knull (in OSU). 



Discussion. — This species is quite similar to ochraceus. In the latter 

 species, elytral striae six and seven are largely to entirely confused, 

 and specimens are knoAvn only from Florida. In implacidus, elytral 

 striae six and seven are even to somewhat confused, and specimens
