CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 657 



marked by regular row of crowded, very coarse, elongate punctures; 

 anterior lobe moderately tumid, with two irregular rows of coarse 

 punctures laterally and subapically, disc of calli and midline with 

 scattered, fine punctures; posterior lobe with numerous punctures, 

 these coarser on apical half; umbones impunctate. 



Scutellum: Length-width ratio, 0.56:0.67. 



Hemelytron: Apical half of mesocorium mostly impunctate; exo- 

 corium abundantly punctate for full width. 



Propleuron: Prosternal carinae about as high as labial II, obtusely 

 triangular. 



Legs: Anterior femur ventrally with large, unevenly furcate spine 

 near basal third; anterior tibia with low, blunt angulation near middle 

 of ventral margin; posterior femur dorsally with subapical angulation, 

 ventrally with weakly curved, subapical spine about as long as two- 

 thirds femoral height. 



Terminalia: Gonostylus as illustrated (fig. 297). 



Length of body: 2.47. 



Type data.— Holotype male (USNM 64409), "Martinique, W. I., 

 8-21-29, Bartsch-Hoffmann." 



Discussion.— The following species, described as new on the basis 

 of six distinct pegs on the apex of the clypeus, may be sunply the female 

 of radialis. Female specimens that run to the present species should 

 be checked against the next one to determine if they are not the same 

 and to help evaluate the feature of the additional pegs on the clypeus.

Diagnosis. — The present form, if not based on an aberrant indi- 

 vidual, is unique within the genus in possessing six pegs at the apex of 

 the clypeus, the usual four along the margin and one above and one 

 below the margin on the midline (fig. 60). 



Description. — Based on one female. Oval, widest behind mid- 

 length. 



Head: Length about four-fifths width, 0.47:0.58; interocular width, 

 0.32; clypeus slightly surpassing apices of juga, with six pegs apically, 

 usual four along margin and one above and one below margin on mid- 

 line (fig. 60) ; surface with coarse punctures between eyes. Antennal 

 segments: I, 0.12; II, 0.05; III, 0.23; IV, 0.31; V, missing. Labium 

 attaining middle coxae. Labial segments: I, 0.16; II, 0.26; III, 0.23; 

 IV, 0.16. 



Pronotum: Length about three-fourths width, 0.83:1.36; anterior 

 margin shallowly concave; lateral margins strongly narrowing from 

 base, straight on basal half; transverse impression strong only at ends, 

 marked by irregular row of coarse punctures; anterior lobe with two
