CYDNIDAE OF THE WESTERN HEMISPHERE FROESCHNER 431 



punctures; posterior lobe with numerous prominent, elongate punc- 

 tures over entire surface, sometimes with short, longitudinal rugulae 

 between. 



Scutellum: Longer than wide, 1.19(1.13-1.23) :0.96(0.93-1.01); 

 sm-face sculpture similar to but less dense than that of posterior 

 pronotal lobe. 



Hemelytron: Clavus and corium alutaceous; clavus with one or 

 two partial rows in addition to one complete ro\v of punctures; meso- 

 corium with two complete rows of punctures parallehng claval suture, 

 elsewhere with well-separated punctures becoming much finer apically; 

 punctation of exocorium similar to but more dense than that of 

 mesocorium; costa without setigerous punctures; membranal suture 

 straight, lateral angle not produced; membrane longer than basal 

 width, usually just reaching apex of abdomen. 



Propleuron: Shining, with numerous irregular, anastomosing, 

 longitudinal rugae; prosternal carinae almost as high as labial II, 

 abruptly terminated posteriorly. 



Mesopleuron: Evaporatorium extended into posterolateral angle, 

 not reaching lateral margin of segment; lateral area in part rugo- 

 punctate. 



Metaplem-on: Terminal lobe of peritreme semicircular, reaching 

 almost to convex lateral margin of evaporatorium; lateral area in 

 part rugopunctate. 



Legs: Anterior tibia with five or sLx stout spines dorsally. 



Sternites: Shining and minutely punctate on middle half, coarsely 

 rugopunctate on lateral fourth. 



Terminalia: Genital capsule shining, distinctly punctate in lateral 

 angles, apical margin straight; gonostylus as illustrated (fig. 209). 



Length of body: 3.32(3.18-3.42). 



Female: Smiilar to males, measurements averaging larger. 



Head: Length-width ratio, 0.60(0.50-0.64) : 0.83 (0.80-0.91) ; inter- 

 ocular width, 0.59(0.56-0.63). Antcnnal segments: I, 0.17(0.16- 

 0.20); II, 0.18(0.15-0.20); III, 0.19(0.14-0.24); IV, 0.25(0.25-0.26); 

 V, 0.34(0.33-0.37). Labial segments: I, 0.22(0.19-0.26) ; II, 0.42(0.36- 

 0.51); 111,0.31(0.26-0.36); IV, 0.26(0.24-0.33). 



Pronotum: Length-width ratio, 0.94(0.90-1.03) :1.73(1.62-1.87). 



Scutellum: Length-width ratio, 1.26(1.13-1.34) : 1.04(0.90-1.16). 



Length of body: 3.43(3.25-3.60).
