TAXONOMIC STUDY OF MORDELLIDAE RAY 303 



Remarks. — The type and a male paratype were collected at Coliseo, 

 Province of Matanzas, Cuba, June 15, 1934 (S. T. Danfortli). The 

 allotype and a female paratype were collected at Central Jaronu, 

 Cuba, June 2, 1930, on weeds and grasses (L. C. Scaramuzza) and 

 Central Jagueyal, Cuba, June 30, 1927, on grasses (L. C. Scara- 

 muzza). 



MORDELLISTENA LATIPALPALIS, new species 



Figure 18, i 



This species is rather closely allied to aequinoctialis Champion 

 (1891, p. 311) but may be separated from the latter member of the 

 genus without difficulty by means of the much smaller size, the dif- 

 ferent character of the antennal segments, the broader terminal seg- 

 ment of the maxillary palpi of the male, and the general difference 

 in color. 



Length : 2.95 mm. ; including anal style, 4.15 mm. Form elongate, 

 narrow, sides subparallel, attenuate, and gradually rounded caudad 

 from middle of elytra. Dermal color dark fuscocastaneous, legs, 

 except posterior femora, maxillary palpi, antennae, two basal seg- 

 ments lighter, apex of front, and clypeus, flavocastaneous. Surface 

 rather densely covered with fine, recumbent, yellowish-white pubes- 

 cence, densest on elytra, abdomen, and anal style ; eyes sparsely cov- 

 ered with short, whitish hairs. 



Antennae 1 mm. long, slender, reaching intermediate coxae; seg- 

 ments 1 and 2 subequal; 3 and 4 equal in length, narrow; 5-10 each 

 one-third longer and broader than 4, lateral margins straight, mesal 

 margins curved, broadest at apex; 11 one-half longer than 10, sides 

 and apex rounded, broadest medially. Distal segment of maxillary 

 palpi enlarged, somewhat pear-shaped, broad, mesal margin straight, 

 lateral margin and apex broadly rounded, greatest width on apical 

 third. Pronotum distinctly broader than long (0.95 by 0.85 mm.), 

 apex and sides rounded, basal angles subacute, forming a right 

 angle, base arcuate, midbasal lobe moderately produced, subtruncate. 

 Scutellum broadly subtriangular, broader than long, apex abruptly 

 transversely truncate, angles obtuse. Elytra distinctly more than 

 twice as long as broad (2.1 by 0.95 mm.), sides subparallel on basal 

 half, narrowly attenuate caudad, broadly rounded on caudal fourth, 

 apices individually rounded. Hind tibiae with two oblique ridges 

 extending halfway across outer surface ; basitarsi with three, second 

 segment with two oblique ridges, all extending halfway across outer 

 surface. Tarsal claws with four teeth, the distal three long, acute, 

 postmedian, proximal one short, blunt, and median in position (fig. 

 18, j). Anal style elongate, narrow, attenuate to apex, three times 

 length of apical ventral segment (1.2 by 0.4 mm.) ; last ventral seg- 

 ment three times as long as penultimate one.
