VESPOID AND SPHECOID HYMENOPTERA COLLECTED IN 

 GUATEMALA BY W. P. COCKERELL. 



By S. A. RoHWER, 



Of the Bureau of Entomology, United States Department of Agriculture, 



Shortly after Mrs. Cockerell returned from Guatemala in 1912, 

 Prof. T. D. A. Cockerell referred to me, for naming, all the wasps 

 which had been collected; but, due to the fact that very little time 

 could be spent in studying this collection, it was not until recently 

 that all the species have been worked up. The following is a report 

 of every species submitted. As will be seen, a number of them were 

 undescribed, and descriptions of these have been added. 



The collection, as here reported upon, has been given to the United 

 States National Museum by Professor Cockerell. 



POLISTES INSTABILIS Saussure. 



Two workers were collected February, 1912, one from Gualan and 

 one from Quirigua, Guatemala, 



NECTARINA LECHEGUANA (Latreille). 



Two workers collected at Amatitlan, Guatemala. 



PARACHARTERGUS APICALIS (Fabricius). 



Two females collected at Guatemala City, Guatemala, and one 

 female collected at Gualan, Guatemala, February 10, 1912. 



PSEUDOCHARTERGUS CHARTERGOIDES (Gribodo). 



One worker collected at Quirigua, Guatemala, on flowers of Zexme- 

 nia virgulata. 



This is the first record of this species north of Panama. 



POLYBIA OCCIDENTALIS (Olivier). 



Five specimens collected at Gualan, Guatemala, and five at Quiri- 

 gua, Guatemala, one on flowers of Ipomoea quinquefolia. 



Most of these specimens are rather darker than the typical form, 

 the yellow bands on the abdomen being narrower and the yeUow of 

 the metanotum being reduced or in two cases wanting.

 Not hitherto recorded from Guatemala. 



STELOPOLYBIA MERIDIONALIS R. Ihering. 



One worker collected at Guatemala City, one at Quirigua, two at 

 Gualan, on flowers of Verononia aschenborniana, and one iit Ama-
