TAXONOMIC STUDY OF MORDELLIDAE — RAY 297 



of posterior tibiae twice as long as inner one. Anal style almost 

 three times length of apical ventral segment (0.28 by 0.1 mm.), stout, 

 dorsal surface rounded to apex, latter acute, bearing several short, 

 black bristles ; ventral surface straight ; last ventral segment but twice 

 as long as penultimate one. 



Type locality. — Paraiso, Canal Zone, Panama. 



Type. — A unique male, U.S.N.M. No. 52919, collected on April 22,

Reiivirks. — This species is named for Dr. A, Dampf, chief en- 

 tomologist of the Mexican Department of Agriculture, who so largely 

 contributed to the possibility of this work by sending an assortment 

 of 802 specimens collected over a period of years.

MORDELLISTENA CANDELABRA, new species 

 FiGXiRES 16, k; 18, g 



This species is most closely allied to xanthopyga Champion (1891, 

 p. 344) and may be separated from the latter member of the genus 

 by the difference in color pattern, the peculiar shape of the distal 

 segment of the maxillary palpi, the longer length of the third 

 antennal segment, and the presence of but a single spur at the apex 

 of the posterior tibiae. 



Length : 1.82 mm. ; including anal style, 2.38 mm. Elongate, nar- 

 row, sides subparallel; body flavocastaneous, eyes and ridges on 

 posterior tibiae and tarsi fuscocastaneous, elytra and ventral ab- 

 dominal segments (except distal segment) piceocastaneous. Sur- 

 face covered with fine, recumbent, uniform pubescence, partaking of 

 ground color, with contrasting areas on elytra, as follows: a broad 

 humeral patch extending obliquely into disk and reaching suture; 

 a broad, transverse, postmedian band; and a broad sutural line con- 

 necting the preceding two. 



Antennae 0.48 mm. long, reaching base of lateral pronotal margin ; 

 segments 1 and 2 large, equal ; 3 distinctly longer but narrower than
