suture weakly bisinuate; membrane longer than basal width, sur- 

 passing apex of abdomen. 



Propleuron : Feebly alutaceous, punctate in depression and anterior 

 to acetabulum; prosternal carinae less than half as high as labial II. 



Mesopleuron: Lateral area impunctate, weakly rugose. 



Metapleuron: Lateral margin of evaporatorium distinctly con- 

 cave; lateral area impunctate. 



Legs: Not specially modified, posteroventral margin with five 

 preapical spines. 



Sternites: Shining, impunctate. 



Terminalia: Genital capsule shining, with few punctures laterally; 

 gonostylus as illustrated (fig. 234). 



Length of body: 5.23(4.30-5.70). 



Type data.— Holotype male (USNM 64423), "Barro Colo. Id., 

 C.Z., VII-VIII-42, Jas. Zetek, No. 4985." Paratypes, four males: 

 Same data as holotype (RCF); same locality and collector, Jan. -Feb. 

 1945 (USNM), Jan.-Feb. 1944 (USNM), April 1945 (USNM). 



Discussion. — The only habit note attached to any specimen was 

 the conventional "at light." 



Pangaeus (^Pangaeus) rufobrunneiis Jensen-Haarup 



Pangaeus rufobrunneus Jensen-Haarup, 1926, p. 49. 



Diagnosis. — The combination of the four or five submarginal 

 setigerous punctures on the jugum, the virtual absence of distinct 

 punctures laterally on the anterior lobe of the pronotum and the 

 presence of three or four setigerous punctures on costa sets this species 

 apart from all others in the subgenus. 



Description. — From one specimen, the type. Female: Oval, 

 broadest behind midlength. 



Head: Length slightly more than two-thirds width; 1.10:1.60; 

 interocular width, 0.99; anterior outline semicircular, clypeus as long 

 as juga, very slightly narrowed at apex; line on either side of clypeus 

 extending posteriorly to between ocelli where they diverge around a 

 median fovea; surface with numerous minute punctures on coarse, 

 radiating rugae; jugum with submarginal row of four close-set punc- 

 tures in front of eye and one separated distally; ocelli small, separated 

 from eye by space about three times transverse ocellar width; jugum 

 ventrally and maxillary plate (except at posterior margin) polished, 

 impunctate. Antennal segments : I, 0.3 1 ; II, 0.37 ; III, 0.39, IV, 0.46 ; 

 V, 0.54. Bucculae about as high as labial II; labium attaining base 

 of middle coxae. Labial segments: I, 0.53; II, 0.80; III, 0.72; IV, 

 0.43. 



Pronotum: Length more than half width, 1.82:3.31; anterior mar- 

 gin deeply, simply emarginate; lateral margins not sinuate, with
