■1 ; 5-10 each successively shorter and narrower than preceding ; 11 as 

 long as 1, spindle-shaped, broadest subbasaliy, attenuate to apex. 

 Distal segment of maxillary palpi enlarged, elongate, with form of a 

 scalene triangle, sides and apex but slightly rounded (fig, 16, k). 

 Pronotum but slightly broader than long (0.56 by 0.52 mm.), apex 

 and sides rounded, basal angles obtuse, base arcuate, midbasal lobe 

 short, rounded. Scutellum small, triangular. Elytra two and four- 

 tenths times as long as broad (1.26 by 0.52 mm.), sides gradually 

 narrowing to within one-fourth of apex, where they become broadly 

 rounded, apices individually rounded. Penultimate segment of an- 

 terior and intermediate tarsi filiform. Posterior tibiae with a short 

 subapical ridge, a short median one, and a long oblique one extending 

 entirely across outer surface near basal articulations; basitarsi with 

 two short, oblique ridges, each very oblique ; second segment with one 

 short, oblique ridge. Tarsal claws with two distinct, broad teeth, 

 distal one longest, and a small, blunt, median elevation on concave 

 surface (fig. 18, g). Outer spur of posterior tibiae more than half 

 iis long as basitarsus; inner spur ladling. Anal style tAvo and two- 

 thirds times as long as apical ventral segment (0.55 by 0.2 mm.), 

 narrow, evenly attenuate to apex. 



Type locality. — Panama City, Panama. 



ry;>f .— Male, U.S.N.M. No. 52939. 



Remarks. — Seven specimens: The type and a male paratype were 

 taken at Panama City, Panama, April 12 (A. H. Jennings) ; the allo- 

 type and two female paratypes were taken at Paraiso, Canal Zone, 

 Panama, on January 17, 1911, and April 18, 1911, respectively (E. A. 

 Schwarz) ; a female paratype was taken at Pedro Miguel, Canal Zone. 

 Panama, April 17, 1911 (E. A. Schwarz). 



I have been unable to find the shorter spur of the posterior tibiae in 

 any of the seven specimens at hand ; in the absence of any damage to 

 the series this peculiarity is unaccountable. If this is the normal case 

 for this and several otlier species, it is the first occurrence of such an 

 omissioi\ in the family. 



The males of candelahra are darker tlian the females, with ventral 

 surface of abdomen a uniform piceocaslaneous (except distal segment).
