TAXONOMIC STUDY OF MORDELLIDAE — RAY 2^9 



oblique ridge, all extending halfway across outer surface. Tarsal 

 claws with four distinct teeth, basal one shorter than others and 

 obtuse (fig. 18, 5). A single spur on posterior tibiae, thick, two- 

 thirds as long as basitarsus. Anal style almost three times as long 

 as apical ventral segment (0.28-0.4 by 0.1-0.15 mm.), fairly stout, 

 attenuate to apex; last ventral segment but twice as long as 

 penultimate one. 



Type locality. — La Ceiba, Honduras. 



rype.— Male, U.S.N.M. No. 52913. 



Remarks. — The type was collected at La Ceiba, Honduras, August 

 25, 1916 (F. J. Dyer). A male paratype was taken at Peto, Yucatan, 

 Mexico, August 9, 1925, at about 30 meters elevation, in a dense bush 

 forest (A. Dampf ) . This latter specimen has the pronotum fuscopice- 

 ous, except for a small flavous area at middle of lateral margin, the 

 seven apical segments are slightly darker than in the type, and the 

 basal elytral spot is smaller, so that it does not reach the lateral 

 margin. Structurally the paratype, even including the nature, dis- 

 position, and length of the teeth on the tarsal claws, is identical 

 with the type.

Figures 16, & ( 5 ), d ( 9 ) ; 18, d 



This species may be separated from both diluta Champion (1891, 

 p. 338) and emarginata., new species, described below, by the complex 

 maculation of the elytra, the very peculiar shape of the distal seg- 

 ment of the maxillary palpi in the male, the much greater length 

 of the second over the first antennal segment, the equal length but 

 greater width of segment 4 over segment 3, the longer com- 

 parative length of the apical ventral segment, and a distinct differ- 

 ence in the form of the tarsal claws. 



Length: 1.07 mm.; including anal style, 1.5 mm. Elongate, nar- 

 row, sides subparallel, narrowing only one-fourth from apex of 

 elytra, broadest at middle of pronotum. Head (including mouth 

 parts and antennae), pronotum, and elytra, flavocastaneous, latter 

 part with the following piceous areas : a triangular humeral patch, 

 a Y-shaped sutural area at base narrowly connected to humeral 

 patch, a broad marginal spot at middle extending halfway to suture, 

 and an ai-ea covering apical sixth; ventral surface flavocastaneous, 

 abdomen slightly darker (base and sides of mesosternum and sides 

 of metasternum up to a point parallel with posterior coxae, piceocas- 

 taneous in female) ; ridges of posterior tibiae and tarsi piceous. Sur- 

 face densely covered with fine, recumbent pubescence, partaking of 

 ground color.
