The references in literature to this species are very numerous. 

 Tlie above are the most important. 



Black. Antennae and mouth-parts yellow. Thorax dull black 

 smooth, with a few impressed points. Legs uniform yellow! 

 Abdomen rather broad, all the segments recurved at the sides 

 in the J, the sides regular and in some specimens forming a 

 longitudinal keel ; in the $ the sides are merely convex and 

 smooth. The whole of the abdomen is sparsely covered with 

 impressed points. Last dorsal segment of (S rectangular, parallel- 

 sided, broader than long, with a median impression, the posterior 

 margin straight; similar in the $, but somewhat narrower. 

 Branches of the forceps in the c? remote at the base; in the 

 basal third stout, straight, trigonal and somewhat dilated, especially 

 the right branch ; asymmetrical, the left branch being gently and 

 regularly incurved and tapering, while the right branch is abruptly 

 curved inwards, so that the apical third of the branch is at rif^ht 

 angles to the longitudinal axis of the insect ; the outer margin 

 presents a regular curve ; the inner margin is curved in a semicircle 

 and shows a rectangular projection at the basal third where the 

 attenuation is sudden. In the $ the branches are symmetrical, 

 subcontiguous, trigonal, nearly straight, unarmed, and tapering. 



Length of body 15-23 mm. 21-23 mm. 



forceps 3-3-5 „ 3-5-4-25 „

This species, apparently indigenous to the Pal^arctic 

 Eegion, has been transported by shipping to all parts of the 

 world and has quickly naturalised itself wherever possible. 



Its usual haunts are the banks of rivers and coasts of seas 

 but it sometimes occurs on mountains at a considerable elevation' 

 as in the above noted instances in Tenasserim ; and de Bormans 

 records it from Mount Lebanon. It probably occurs also in the 

 mainland of India in suitable localities. 



Although generally considered a stable species, A. maritima 

 varies within certain limits, as Scudder first pointed out. That 

 author refers to two males from South Carolina, with forceps
