 Female genitalia with spermathecal head kidney-shaped, 



often with top-knot; tail swollen, weakly curved (Fig. lOOe) 



(7 dissected) . 



Stridulatory files present on occipital region of male 

 heads; absent on females. Males have a slight lateral 

 extension of prosternum; extending 0.33 distance from 

 sutural notch at anterior prosternal margin to lateral edge 

 of prothorax (Fig. 13) . Females have foveate punctures on 

 prosternum in front of procoxae; males lack these punctures. 



Variation . The basal and anterior pronotal spots are 

 often sguared and connected at the margin. The majority of 

 specimens has the connection less than half the spot's 

 length. In a specimen from Panama these spots appear as 

 single large spots. 



Most specimens have the subhumeral spot free, and the 

 scutellar and central spots well separated. In a few, the 

 subhumeral spot touches the scutellar spot. One specimen, 

 from Tobago, has the subhumeral spot fused with the 

 scutellar spot. This specimen also has the scutellar and 

 central spot connected from the suture to stria III 

 (Lacordaire' s "variete A"). The other specimens studied 

 have this connection narrowed to stria I or lacking. 



Type . No specimen could be identified as a "type" of 

 Ischyrus incertus . Lacordaire gave no indication where the 

 "type" specimens were deposited, and their current location 

 is unknown. Lacordaire stated in the original description
