shining black, dark reddish at the base and sides, with a dull 

 black band as on the preceding segment ; towards the middle it

 pair of more distant, less prominent, rounded, reddish protuberances ; 

 fifth segment in the shape of two scales, reddish at base and black 

 at apex ; genitalia hemispherical, large, bare, dark reddish above, 

 yellowish below, with two appendages beneath. Venter shining 

 black, much hollowed between the sternites, which are prominent 

 below, forming a sort of channel. Legs entirely yellow, including 

 coxae and trochanters, the femora at end and the tarsi darker, but 

 not black ; all the femora are incrassated and a little bent. Wings 

 wholly hyaline, vitreous, with black veins ; third vein straight ; 

 subcostal cell entirely blackish, the stigma therefore very con- 

 spicuous, in the shape of a black line.

 the base of the antennae, becoming reddish in front. Thorax and 

 scutellum as in the male, the dorsum blacker. Abdomen narrow 

 and elongate ; first and second segments wholly black, shining ; the 

 others dark reddish, shining, with bluish reflexions, without any

Genus 7. XANTHOGRAMMA, Schiner (1860). 



I have placed in this genus, taken in a broader sense, the species 

 which cannot remain in &i/rjjJuts, on account of the complete bright 

 yellow lateral stripes of the thorax, nor in SjiJicero^horict, on 

 account of the different abdomen and genitalia. They can be best 

 included provisionally in the present genus, though having a slightly 

 different facies from the typical species, chiefly on account of the 

 abdomen being not so broad. The recently erected genus IscJii- 

 odon, Sack (1913) applies to the species of the group scuteUare- 

 CBgyptium ; this name can perhaps be used for all the species men- 

 tioned below : 



1 (2) Third anteimal joint ovate, elongate ; 



front coxse mainly black ; yellow lateral 

 stripe on thorax passing- the suture, but 

 not reaching the scutellum ; hind tro- 

 chanters of the male with a strong spine 

 and front tarsi with the internal claw 

 bifid at end (Ischiodon) eeyyptium, Wied. 



2 (1) Third autennal joint rounded, short ; front 



coxae wholly yellow ; lateral yellow 

 stripe on the thorax complete, reaching 

 to the scutellum ; hind trochanters and 

 fore tarsi of malt? simple.
