172 MONOGRAPHIC 



rotundate, lateral margin with a black band extending to 

 the occiput ; vertex with an horse-shoe shaped depression ; 

 eyes flat ; antennae long, the first joint large, cylindrical, 

 second only the half the size, sub-conical, third acutely 

 hooked, last two small, nearly equal; prothorax sub-conical, 

 narrower than the head ; metathorax quadrangular, both 

 with a broad concave black lateral margin; abdomen nearly 

 filiform, the first seven segments with a pitchy-black trape- 

 zoidal lateral spot on each side, last two entirely pitchy, 

 rather paler ; legs very long, with the superior margin of 

 the coxae, femora, and tibiae black, base of the latter with a 

 black annulus ; anterior femora enlarged. Length 2. 



The only specimens I have seen of this species, I took 

 from a White Stork (Ciconia alba), in 1829. Dr. Bur- 

 meister says, " segmentis abdominalibus fascia lata-nigra 

 primis 3 interruptis" In my specimens this character 

 formed the exception. I believe only one had the lateral 

 spots united so as to form fasciae, the general character 

 was as represented, with a dorsal pale line, the whole 

 interrupted.
