0. flaviguttula Godg. 



Female. — Very slender; not coarsely punctured, sparsely pubescent. Face 

 yellow, punctures dark ; clypeus rounded, extending below marginal line of 

 cheeks ; clypeal sutures, inner margins of eyes, ocelli, spots at base of vertex 

 over ocelli, and callosities of pronotum, red. Median carina of pronotum black, 

 interrupted by mid-dorsal white spot. Pronotum not reaching apex of elytra, 

 testaceous, pattern obscurely indicated. Obsolete parallel reddish bands ex- 

 tending from pronotal callosities straight back over humeri. White vittae ris- 

 ing from mid-lateral pronotal margin to junction with mid-dorsal transverse 

 white spot, narrowly bordered posteriorly with dark reddish ; apical fourth with 

 obsolete sub-apical transverse white vitta bordered obscurely with blackish. 

 Dark border of pronotal mid-lateral white vitta continued in band across 

 elytron, broadly whitish before it ; base and apex of elytra dark, otherwise 

 hyaline. Beneath pale; femora above, tibiae in front, black. Length s l A mm. 



Described from specimen in author's collection, taken by him at Bronx- 

 ville, Westchester County, N. Y., July 4, 191 1, on hickory. 



It will be noted that aside from differences in color or shade the 

 above two descriptions present two other conspicuously inconsistent 

 characters, i.e., Dr. Goding describes his specimen as densely pubes- 

 cent (thereby suggesting pubescens) instead of sparsely pubescent; 

 and, although describing the elytra, makes no reference to the mid- 

 elytral dark band, so notable in the Bronxville specimen. However, 

 both in respect to degree of pubescence and the presence of the 

 elytral band, an actual comparison of the latter specimen with that 

 in the National Museum supposed to have been determined by Dr. 

 Goding as his flaviguttula discloses no appreciable difference between 

 them. 



In addition to the above four specimens a comparatively large 

 series has been studied by me which by reason of depth of color and 

 sharp definition of pattern I have been disposed to regard as consti- 

 tuting still another species. These range from bright red to black 

 in both sexes. Those in my collection I had provisionally designated 

 as 0. definita n. sp. But in view of their gradation in coloring toward 

 the specimen in the National Museum bearing the record of Dr. 

 Goding's determination above referred to (though none is quite so 

 pale and obscurely patterned), their similarity in size, and apparent 

 lack of other structural differential character, I hesitate to give them 

 separate specific rank, and for the present would associate them as 

 variety definita with what is here regarded as typical flaviguttula
