MORDELLISTENA LUCIDOVIRGA. new species 



Figure 28, /, m 



This species is most closely allied to ephippium, described below, 

 and can be separated by the different color and maculation of the 

 entire body, the two ridges on the hind basitarsus, and the different 

 shape of the tenninal segment of the maxillary palpus. 



Length: 2.15 mm; including anal style, 3 mm. Elongate, narrowly 

 subcuneate; derm of head and thorax fuscous with fuscocastaneous 

 margins; elytra piceous, with a broad castaneous discal stripe extending 

 from base almost to apex; antennae fuscocastaneous; maxillary palpi 

 and legs flavous, except posterior femora, which are black; ventral 

 surface piceous. Surface densely covered with fine recumbent 

 pubescence, partaking of ground color. 



Antennae 0.75 mm long, reaching posterior coxae; segments 3 and 

 4 equal; 5-10 each one-half longer but very little broader than 4; 

 11 rounded, slightly longer than 10. Apical segment of maxillary 

 palpi enlarged, triangular, outer margin concave, other sides straight, 

 corners rounded. Pronotum slightly broader than long (0.65 by 0.6 

 mm), sides rounded, base arcuate, midbasal lobe short, rounded. 

 Scutellum small, triangular. Elytra almost three times as long as 

 broad (1.55 by 0.65 mm), sides narrowly rounded, apices individually 

 curved. Posterior tibiae with two oblique ridges, the anterior ex- 

 tending entirely across outer face ; basitarsus and second segment each 

 with two ridges, each extending halfway across outer surface. Anal 

 style two and one-half times as long as apical ventral segment, stout, 

 truncate at apex. 



Type locality. — Maricao, Puerto Rico. 



Type.— Feimde, U.S.N.M. no. 51605. 



Remarks. — The type, a unique, was taken at Maricao on July 2, 

 1917, by H. Morrison.
