CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 497 



Length of body: 5.28. 



Type data. — Known only from the holotype male (BiM), "Maza- 

 runi: High Forest, 20, viii, 1937, British Guiana: coll. Richardson & 

 Smart. B. M. 1937-776." 



Discussion. — The unusual punctation of the pronotum is unique 

 within the genus and suggested the trivial name. Additional com- 

 ments on this species may be found in the discussion of rugonotum 

 which is also described as new in this paper. 



Pangaeus {Pangaeus) quinquespinosiis, new species 



Plate figures 83, 158, 234 



Diagnosis. — The male of this species can be recognized from the 

 others with a single submarginal setigerous puncture anterior to each 

 eye and polished coria by the simple posterior tibiae which have five 

 preapical spines on the posteroventral margin. 



Description. — Male: Oval, sides subparallel. 



Head: Length more than two-thu-ds width, 0.89(0.87-0.91) :1.36 

 (1.30-1.41); interocular width, 0.78(0.73-0.83); anterior outline semi- 

 circular, weakly angulated medially, juga longer than and narrowly 

 continguous beyond clypeus; surface polished, impunctate, with 

 mostly obsolete, radiating rugae; ocelli moderate, separated from eye 

 by space almost twice transverse ocellar width; jugum ventrally and 

 maxillary plate, except basally, shining, impunctate. Antennal seg- 

 ments: I, 0.25(0.24-0.26); H, 0.24(0.23-0.26); HI, 0.33(0.32-0.36); 

 IV, 0.43(0.40-0.50); V, 0.55(0.51-0.58). Bucculae almost as high as 

 labial H; labium reaching between middle coxae. Labial segments: 

 I, 0.42(0.40-0.46); II, 0.68(0.66-0.73); III, 0.52(0.47-0.56); IV, 

 0.35(0.34-0.40). 



Pronotum: Length more than half width, 1.47(1.34-1.56) : 2.73 

 (2.47-2.86); anterior margin shallowly, doubly emarginate; lateral 

 margin straight on basal half, with five setigerous punctures sub- 

 marginally; transverse impression weak to obsolete medially, dis- 

 tinctly impressed laterally, marked by medially interrupted, regular 

 row of close-set punctures merging laterally with few scattered punc- 

 tures on both lobes; posterior lobe with less than a dozen punctures 

 medially. 



Scutellum: Length subequal to or shorter than width, 1.60 

 (1.42-1.69) 11.61(1.43-1.75); disc shining, with numerous punctures 

 except at base and apex. 



Hemelytron: Clavus and corium polished; clavus with single row 

 of punctures; mesocorium with two complete rows of coarse punctures 

 paralleling claval suture, discally with fine punctures becoming denser 

 towards base and apex; exocorium finely and more densely punctate 

 than mesocorium; costa with one setigerous puncture; membranal
