pubescent, black : a line of fuscous pubescence extends longitudinally 

 between the first and the third striae, gradually diverging from the 

 suture, and extending laterally at the apex ; between the fourth and 

 seventh striae is another longitudinal line, more distinctly flavous, 

 which extends (near the shoulders) as far as the margination, and 

 terminates before it arrives at the base : antennae filiform, long and 

 slender ; joints one to three and five to seven piceous, four, and eight 

 to ten pale testaceous, the eleventh fuscous. Legs pale testaceous ; 

 the anterior tarsi (and base of the tibiae) rufo-testaceous ; the base 

 of the posterior femora is fuscous, and the globular inflation above the 

 posterior claw bright rufous.
