Antennae 0.85 mm long, reaching base of metasternum; segment 

 4 one-half longer than 3; 5-10 each as long as 4 and slightly broader; 

 11 rounded, no longer than 10. Apical segment of maxillary palpi 

 enlarged, club-shaped, broadest subapically, then rounded to distal 

 end. Pronotum but slightly broader than long (0.75 by 0.7 mm), 

 convex, sides margined, basal angles obtuse, midbasal lobe broad, 

 rounded. Scutellum small, triangular. Elytra almost two and one- 

 half times as long as broad (2.1 by 0.8 mm), sides distinctly rounded, 

 apices individually curved. Posterior tibiae with two oblique equal 

 ridges extending halfway across outer face; posterior basitarsi with 

 three obhque ridges, basal one rudimentary, second segment with 

 two such ridges. Anal style almost three times as long as apical 

 ventral segment, rather tliick and truncate at apex. 



Type locality. — Ad juntas, Puerto Kico. 



T^/pe.— Male, U.S.N.M. no. 51598. 



Remarks. — The type was collected at Adjuntas on March 24, 1933, 

 on orange leaf (R. G. Oakley); the allotype was collected at Villalba 

 on June 21, 1934 (C. M. Matos); a male paratype was collected at 

 Maricao on July 2, 1917 (H. Morrison). No visible external differ- 

 ences in the sexes were noted. 



MORDELIISTENA DANFORTHI, new species 



Figure 28, i 



This species may be separated from indistincta Smith (1882, p. 93) 

 by the bicolorous antennae and ventral abdominal segments and by 

 the broader distal segment of the maxillary palpi. 



Length: 2.4 (male) and 2.3 (female) mm; including anal style 3.5 

 (male) and 3.2 (female) mm. Elongate, subparallel; dermal color 

 flavous, except for the following fuscous areas: Eyes, seven apical 

 segments of antennae, scutellum, elytra (except a broad, Hght, 

 humeral spot extending along base to suture), three apical ventral 

 abdominal segments (except at apex), apical two-thirds of anal 

 style, and ridges and apical setae of hind tibiae and tarsi. Surface 

 densely covered with fine recumbent pubescence, partaking of ground 

 color, except on fuscous portion of elytra, where it is golden. 



Antennae 1 mm long, reaching base of abdomen; segments 3 and 

 4 equal; 5-10 each one-third longer and slightly broader than 4; 11 

 rounded, slightly longer than 10; apical segment of maxillary palpi 

 enlarged, elongate-triangular. Prothorax slightly wider than long 

 (0.75 by 0.7 mm), sides rounded, base arcuate, midbasal lobe short, 

 rounded. Scutellum small, subtriangular. Elytra slightly more 

 than twice as long as broad (1.7 by 0.8 mm), sides parallel, apices 

 rounded. Hind tibiae with two obhque ridges extending halfway 

 across outer face; basitarsi with three, second segment with two
