TAXONOMIC STUDY OF INIORDELLIDAE RAY 283 



MORDELLA MILITARIS, new species 



This species is most closely allied to ogloUini Pic (1930, p. 29) 

 and may be separated from the latter member of the genus by the 

 absence of distinct maculations on the elytra, the more slender, atten- 

 uate anal style, and the smaller size. In the synopsis of the Argen- 

 tinian species of Mordella (Pic, 1936, pp. 114, 115) jnilitaiis keys out 

 to oglohlini. 



Length: (male) 5.85 and (female) 7.35 mm.; including anal style, 

 (male) 8.1 and (female) 9.35 mm. Elongate, sides narrowing pos- 

 teriorly to apex of elytra, body subcuneate in shape; dermal color 

 piceous, except for basal three-fourths of elytra, which are golden- 

 brown. Surface densely clothed with fine, recumbent pubescence, par- 

 taking of gTound color, except for the following whitish areas : head ; 

 pronotum, densest on lateral and basal margins ; elytra, condensed on 

 suture and apex of golden-brown area; mesosternum and meta- 

 sternum; basal margins of ventral abdominal segments, densest at 

 lateral edge ; base of anal style ; legs. 



Antennae (male) 2.2 and (female) 2.4 mm. long, reaching posterior 

 coxae ; segments 3 and 4 equal in length ; 5-10 distinctly serrate, each 

 slightly longer and twice as broad as 4; 11 rounded, slightly longer 

 than 10. Distal segment of maxillary palpi enlarged, with form of a 

 scalene triangle, outer margin distinctly curved, cephalic surface with 

 a median, elongate depression. Prothorax distinctly broader than 

 long (1.6 by 1.5 mm.), sides rounded, base arcuate, basal lobe short, 

 subtruncate. Scutellum small, subtriangular, sides and apical angle 

 rounded. Elytra twice as long as broad (3.6 by 1.8 mm.), sides 

 straight, attenuate to apex, apices individually rounded. Tarsal 

 claws with seven teeth, the distal one longest, successively shortening 

 proximad, the proximal one scarcely more than rudimentary. Anal 

 style slightly more than twice as long as apical ventral segment, 

 slender from a dorsal view, attenuate to apex. 



Type locality. — Argentina. 



Type. — Male, in the collection of the Deutsches Entomologisches 

 Institut. 



Remarks. — A male and female example (type and allotype), with 

 the data merely as "Argentina — Coll. Kraatz," contains all available 

 information. There is no visible external difference between the sexes. 

 The middle tarsi are missing in both specimens. 



MORDELLA SUMMERMANAE, new species 



This species cannot be closely allied with any of the known North 

 American forms. The form of the body, with its subovate form, the 

 extremely short anal style, the short elytra, and the narrow distal
