 pieces of mesosternum darker; anal style fuscous (piceous in male) ; 

 apical setae and ridges of legs })iceous; antennal segments fuscocas- 

 taneous. Body densely covered with fine, recumbent, flavocinereous 

 pubescence.

 2 equal; 3 and 4 equal, each one-third shorter than 2; 5-10 equal in 

 length, each as long as 3 and 4 together, strongly convex on mesal 

 margin; 11 one-fourth longer than 10, rounded, attenuate to apex. 

 Apical segment of maxillary palpus enlarged, broadly scalene-tri- 

 angular, sides slightly curved, corners rounded. Prothorax slightly 

 broader than long, sides rounded, basal angles acute, base arcuate, 

 midbasal lobe short, rounded. Scutellum small, triangular. El}i:ra 

 two and one-half times as long as broad, sides subparallel, apical 

 third strongly curved, apices individually rounded. Posterior tibiae 

 with two equal oblique ridges extending halfway across outer face; 

 posterior basitarsus with iwo, second segment with two oblique ridges. 

 Anal style more than two and one-half times as long as apical ventral 

 segment, moderately slender, evenly attenuate, truncate at apex. 



Ti/pe locality. — Dominican Republic. 



Type.— MdilQ, U.S.N.M. no. 51050. 



Remarks. — Four specimens, one male, three females, are at hand. 

 All w^ere secured in EpideTidruni sp. from the Dominican Republic on

MORDELLISTENA CHAPINI, new species 



This species may be separated from both caHhyana. Champion and 

 epidendrana., described above, by the peculiar coloration of the derm 

 and pubescence on the elytra, the different color combinations of 

 the entire body, the club-shaped terminal segment of the maxillary 

 palpi, the single ridge on the second segment of the posterior tarsi, 

 the slenderer, peculiar antennae, and the smaller size. 



Length: 2.2 mm: including anal stjde, 2.7 mm. Elongate, sub- 

 parallel. Derm bicolored : head and pronotum fuscocastaneous, the 

 latter Avith a mediodor.sal cloud; humeri of elytra with a broad, 

 circular, humoral spot, extending one-fourlh entire length, not touch- 

 ing suture; anterior and intermediate legs flavous, antennae, maxil- 

 lary palpi, and posterior legs fuscoflavous. Body densely covered 

 with fine, recumbent pubescence, parlaking of ground color, except 

 on elytra, where there occurs postmedially a broad, transverse, arcu- 

 ate band (broadest anteriorly at suture) and a large apical area 

 covering apical sixth.
