Metapleiiron (fig. 94): With well-developed auricle, near osteole; 

 evaporatorium extending to lateral margin of segment; lateral area 

 with few distinct punctures near evaporatorium. 



Sternites: Polished, with numerous widely separated punctures on 

 lateral third. 



Length of body: 3.70. 



Type data. — The type female (Copen) bears no locality label 

 although Jensen-Haarup stated "Brazil" as the type locaUty (see 

 discussion below). 



Discussion. — In the absence of a locality label on the type, a 

 question arises as to the source of the locality cited by Jensen-Haarup. 

 One possible explanation is that he derived it from a manuscript 

 "n. sp." label on the pin, the generic name of which was apparently 

 based on the name of that country. Although some doubt may thus 

 arise as to this truly being a species of the Western Hemisphere, the 

 ligulate extension of the peritreme allies it to the present genus — and 

 since this development is not known from any other locality in the 

 world, the logical conclusion is that lucida is a species of the New 

 World. 



Genus Macroporus Uliler 



Macroporus Uhler, 1876, p. 278. 



Diagnosis.— The shape of the osteolar peritreme here extends 

 more than three-fourths of the way to the lateral margin of the 

 metapleuron where it ends in a conspicuous, recurved, polished lobe 



(fig. 91). 



Description. — Small (3.2-4.4), broadly oval, greatest width 

 behind middle; dorsum slightly, venter moderately, convex. 



Head: Length almost three-fifths width, slightly convex above; 

 outline semicircular, clypeus as long as juga; with fine, dorsal carina 

 marginally; submargin, including clypeus, with complete row of 

 coarse, close-set setigerous punctures giving rise to a complete row of 

 pegs and a few hairs; eyes small, entire, moderately projecting; 

 ocelli well developed, moderate in size, situated slightly posterior to 

 line connecting hind margins of eyes, separated from eye by space 

 less than transverse ocellar width; antennae 5-segmented, II shortest 

 and most slender, III, IV, and V increasing slightly in length, all 

 longer than I ; bucculae low, reaching almost to base of head (fig. 30) ; 

 labium reaching between middle coxae, II longest, compressed, 

 without semicircular foliaceous lobe. III longer than I and IV which 

 are subequal. 



Pronotum : Length about half width ; lateral margin entire, slightly 

 convex, narrowing from base; anterior margin deeply and simply
