CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 371 



belongs to a more southern species and leaves the present one without 

 a name. The name proposed above is in reference to the strongly 

 divergent clypeal margins. The numerous illustrations used as char- 

 acteristic of the genus in this paper are the result of following Signoret's 

 definition of the species and considering, admittedly in error, that 

 this was the type of the genus. However, no serious problems should 

 arise if this is duly noted. 



Since divergens is the only species of the genus known to occur far 

 enough north to reach Cuba, Martorell's (1939, p. 186) notes on 

 terginus on that island probably pertain to it. These notes include 

 several interesting biological facts on the species and are quoted as 

 follows : 



This insect becomes a real menace during the rainy nights at La Providence. 

 It is the favorite food of the toad, Bufo marinus L., during this season. About 

 90% of the stomach contents of toads, during the time that these insects were 

 abundant, consists of S. tergimis, according to dissections made by the writer. 

 The toads do not seem to mind the repugnant odor of these bugs. During the 

 first hours of the evening, when the bright lights inside of the School of Agriculture 

 were turned on, these insects would come in great numbers, attracted to the lights.

Diagnosis. — The presence of numerous rows of close-set tubercles 

 that fill the corbicle and extend irregularly to the base of the posterior 

 tibia will easily separate this species from all others in the genus. 



Description, — Based on one female. 



Female: Head: Wider than long, 1.75 : 1.63; interocular width, 

 1.33; width of eye, 0.21; ocellus small, separated from eye by a space 

 IK times ocellar width; juga weakly convex, almost as long as tylus, 

 latter diverging slightly from base to apex. Antennal segments: 

 I, 0.60 ; II, 0.63 ; III, 0.43 ; IV, 0.60. Labial segments : I, 0.60 ; II, 0.66 ; 

 III, 0.46; IV, 0.38. 



Pronotum: Length-width ratio, 2.70 : 4.65; posterior lobe with 

 numerous, scattered, fine, fuscous punctures. 



Scutellum: Length-width ratio, 3.81 : 3.15; with a few fine punc- 

 tures toward sides similar to pronotum. 



Hemely tron : Polished, with scattered fine punctures, those of exo- 

 corium colored like those on pronotum; membrane yellowed, very 

 short, reaching almost to apex of penultimate tergite. 



Legs : Posterior tibia with corbicle and dorsal surface crowded with 

 rows of close-set tubercles (fig. 136). 



Color: Light brown, apices of anterior tibiae slightly darker. 



Length of body: 8.40.
