3f>4 INSECTS ABROAD. 



During life the general hue is yellow, and even after death the 

 yellow stripes upon the thorax are plainly visible. The wings 

 are coloured after a rather curious fashion. They are translucent 

 for nearly two-thirds of their length, and then become gradually 

 tinged with yellow. Across the tips runs a bold dark line, and 

 the extreme tip of the wing beyond this dark line is opaque 

 chrome yellow. 



The speciiic name ornatus, or " ornamented," refers to the 

 coloured wings, while the generic name Mecistogastcr signifies a 

 very long abdomen, and is given to the insect in allusion to the 

 structure of that part of the body.
