544 PROCEEDINGS OF THE NATIONAL MUSEUM vol. in 



Metapleuron: Evaporatorium occupying mesal half, prolonged 

 laterally along anterior margin; peritreme extended about one-third 

 across segment, evanescent apicall}^; lateral area alutaceous and 

 punctate on mesal two-thirds. 



Legs: Moderately long; posterior tibia straight. 



Sternites: Alutaceous, finely punctate, with few irregular rugae 

 laterally. 



Length of body: 6.29. 



Type data. — Holotype female (Wien) labeled "Fiebrig, Paraguay, 

 S. Bernardino." 



Discussion. — As indicated in the key, this species is most closely 

 allied to brevis Signoret and signoreti Mulsant and Key. In addition 

 to the key characters it agrees with these in general habitus, being 

 broadly oval, with a semicircular head, and having the dorsum and 

 venter alutaceous. Its large size (6.29) and creamy white costa 

 separate it from signoreti, while the pale costa and the greater number 

 (about 30:15) of submarginal setigerous punctures laterally on the 

 pronotum distinguishes it from brevis.

Diagnosis. — Among those members of the genus whose body 

 length is less than 6 mm., the broad scutellar apex and lack of distinct 

 punctures towards sides of pronotal lobes will identify this species. 



Description. — Based on the single available specimen which 

 lacked antennae, legs and abdomen, consequently sex is unknown. 

 Oval. 



Head: Length two-thirds width, 0.90 :L36; interocular width, 0.94; 

 surface shining, juga with few obsolete, radiating rugae and numerous 

 very fine punctures; ocelli small, separated from eye by twice an 

 ocellar width; jugum ventrally and maxillary plate impunctate, 

 latter finely alutaceous; antennae missing; bucculae lower than height 

 of labial II. Labial segments: I, 0.40; II, 0.61; III, 0.47; IV, 0.34. 



Pronotum: Length half width, 1.40:2.81; anterior margin broadly 

 and moderately emarginate; side margins strongly converging from 

 base; Vv'ith a single submarginal row of about 25 setigerous punctures; 

 transverse groove slightly behind midlength, very feeble; anterior 

 lobe shining, with fine but distinct punctures behind anterior emargina- 

 tion and a few obsolete punctures laterally; posterior lobe with 

 irregularly scattered moderate to minute punctures.
