ent. Anterior only half as large as posterior and much smaller. Granula- 
tion, color of legs, body, and appendages as in Al. cyanea. The lateral 
appendages are more slender and more pointed, and the hind angles of

Nympha skins, male and female ; and full-grown nympha, dry. Locality, 
Lueneburg, M. Heyer; Keeingsberg, H. Hagen. Length, 42 mm.; breadth, 
9 mm. 
Similar to A#. rufescens, more slender. Head narrower behind; hind 
angles of occiput more rounded. Sides of head not so straight. Mask 
somewhat shorter and broader. Palpus narrower, more convex. Processes 
nearly equal length, enclosing nearly a right angle; tips bent outward. 
Abdomen more slender, uncolored ; lateral spines on segments six to nine. 
Middle appendage shorter and more notched than in AX. rufescens ; lateral 
superiors short, one half length of middle one; male projection nearly as 
long as the lateral superiors, conical, tip rather sharp. 
The species was raised by Miss Olga Poljetajewa, I. c. p. 15. She says the 
nympha is very similar to AS. juncea, except that the lateral spines of abdo- 
men are developed as well as in “E. grandis.
