BEMBIX OCHRACEA Handlirsch 



Figures 146-148 



Bembex ochracea Handlirsch, Sitz. Akad. Wissensch. Wien, Math.-Nat. CI., 

 vol. 102, 1893, p. 864.— Dalla Torre, Cat. Hym., vol. 8, 1897, p. 509. 



The single male specimen that I have doubtfully referred to this 

 species agrees in most respects with Handlirsch's description. It 

 differs in having no fascia on the propodeum; in having a pair of 

 obscure yellow spots on the seventh tergite; and in having on the 

 st^rnites well-developed fasciae, of which that on the second sternite 

 is quite broad and those on the other sternites are broad laterally but 

 are narrowed conspicuously at the midline. These differences in the 

 extent of the maculations are well within the limits of variation 

 found in species of this genus. Handlirsch's type lacked complete 

 antennae. Segments 7-11 of the flagellum of this specimen are 

 excavated below and segments 7-9 are spinose. Segment 11 is some- 

 what dilated and the terminal segment is short, strongly curved and 

 roundly truncate at the apex. The form of the seventh tergite is 

 shown in Figure 148 and the form of the genitalia in Figure 147. 

 The specimen, which is the property of the Zoologisches Museum 

 der Universitate, Berlin, bears the label " Cap Myers " and the 

 number 21616.
