Habits: Several specimens are labeled as taken at light. It is 

 interesting that of the total of 33 specimens examined, only 4 are males.

Zonitis smythi Wolcott, 1950, p. 321. New synonymy. 



Diagnosis: Similar to P. marginata except as follows: Pronotiim 

 frequently with a wide median rufous vitta. Elytra each with a 

 rather broad, fuscous submarginal vitta and a similar subsutm'al one, 

 these united at base and apex and leaving a narrow orange-yellow 

 discal line, or with vittae narrowed and pale fuscous in color, or with 

 vittae entirely absent. Middle of femora and tibial apices some- 

 times weakly infuscate. Length, 9-12 mm. 



Distance separating eyes beneath head varying from one-fifth 

 to two-fifths distance on front. Antennae even more slender than 

 in P. marginata; segments I to III subequal in length. Pronotum 

 as long as or barely longer than wide. 



Male having fore and middle tarsi neither swollen nor expanded, 

 similar in size to hind tarsi. Sixth abdominal sternum cleft, moder- 

 ately impressed, each side evenly tapered, not emarginate, not 

 recurved at base. Genitalia as in figure 8; fused gonocoxites broad, 

 sinuate, abruptly curved dorsad at apex. 



Female having sixth abdominal sternum with an extremely deep, 

 oval emargination medianly. 



Type locality: Of P. obscuricornis, Puerto Rico. Of Z. smythi, 

 Gu^nica, Puerto Rico. 



Geographic distribution: Apparently confined to the West 

 Indies. Recorded from Jamaica, Puerto Rico, and Guadeloupe. 



Seasonal distribution: April to November 6.

 by Enns (1956). The three other species included in this group are 

 presently recorded only from the southwestern United States.
