latter member of the genus by the divergent line of pubescence on 

 the elytra, the rounded mesal edge of the terminal segment of the 

 maxillary palpi, and the larger size. 



Length : 5.4 mm. ; including anal stjde, 6.8 mm. Moderately ro- 

 bust, subcuneate; dermal color black; surface densely covered with 

 fine, recumbent pubescence, partaking of ground color, except for 

 the folloAving whitish areas: head and pronotum completely, con- 

 densed on latter part to form three short, longitudinal, basal bands; 

 scutellum completely; elytra with humeri narrowly and two diver- 

 gent stripes, anterior extending submarginally to within one-sixth of 

 apex and separated from margin by its own width, interior one ex- 

 tending diagonally across disk and joining whitish suture subapically, 

 sides of mesosternum and metasternum densely, bases of abdominal 

 segments, and legs somewhat less distinctly. 



Antennae 1.4 mm. long, scarcely reaching posterior coxae; seg- 

 ments 3 and 4 equal in length ; 5-10 each one-half longer than 4 and 

 considerably broadened; 11 rounded, one-half longer than 10. Distal 

 segment of maxillary palpi enlarged, subtriangular, rounded on 

 mesal surface and apex. Pronotum one-third broader than long 

 (2.1 by 1.6 mm.), convex, sides finely margined, basal angles obtuse, 

 midbasal lobe short, broad, subtruncate. Scutellum twice as broad 

 as long, rounded-triangular. Elytra broadest subbasally, almost 

 twice as long as broad (3.8 by 2.1 mm.), sides attenuate to apex, 

 latter parts individually rounded, distinctly obtuse. Intermediate 

 tibiae and tarsi equal in length. Tarsal claws with four teeth, all 

 somewhat blunt at ends, proximal one rudimentary. Anal style 3 

 times length of apical ventral segment, narrowly truncate at apex. 



Type locality.— Mount Puilsboreau, Haiti. 



Type.—K unique male, U.S.N.M. No. 52930, collected on May 29

MORDELLA LATITHORAX, new specie* 



This species is somewhat allied to Uformis Champion (1891, p. 295) 

 but differs from the latter member of the genus in numerous particu- 

 lars, the most striking of which are the decidedly transverse prono- 

 tum, the equilateral condition of the distal segment of the maxillary 

 palpi, the much narrower and more elongate antennae, and the dif- 

 ferent color. 



Length : 3.5 mm. ; including anal style, 4.8 mm. Form moderately 

 broad, sides parallel posteriorly to middle of elytra, thence broadly 

 rounded to apex; body broadest near base of pronotum. Head cas- 

 taneous, with a piceous rounded spot on vertex reaching occiput and 

 extending laterally in a narrow line to eyes, anteriorly not extending
