 greater part of femora, apex of first and second dorsal segments, blackish ; pubes-

 medially ; head about as wide as thorax, strongly and confluently punctured, the 

 postero-lateral angles slightly evident ; first joint of flagellum about as long as 

 following two united ; thorax distinctly longer than broad, the punctures of upper 

 surface larger and less confluent than those of head, sides scarcely crenulated ; 

 first and second segments sessile, second dorsal witli rounded, separated punc- 

 tures, from which project fine, appressed, golden hairs, which give the segments

Florida ; Texas. This is certainly not the ?> of dubitata Smith, 

 as suggested by Blake (Tr. A. E. S., xiii, p. i43) as it is in nowise
