Subfamily LYG^EIN^E. (Vol. II, p. 2.) 



Genus JETHALOTUS. 



(To follow Astacops, Vol. II, p. 3.) 



^Ethalotus, StSl, En. Hem. iv, p. 98 (1874). 



Astacops, Still (nee Boisd.), Hem. Afr. ii, p. 125 (1865). 



Type, JE. afzelii, Stal, from "West Africa. 



Distribution. Ethiopian and Oriental Eegions. 



" Body very oblong or subelongate ; head short, triangularly 

 produced, deflected ; eyes pedunculate, the peduncle of variable 

 length ; rostrum not passing the posterior coxae ; antenna? with 

 the first joint short, not passing the apex of head ; pronotum 

 trapezoidal ; scutellum equilateral ; hemelytra complete ; legs of 

 moderate length, femora unarmed." (St&l.) 



The above are the generic characters given by StSl when he 

 described (1865) his West African type under the genus Astacops. 

 He subsequently (1874) founded the genus ^thalotus for its 

 reception, giving the following additional characters : " Ocelli 

 about twice as far removed from each other as from eyes ; pro- 

 notuin punctate." 



The position of the ocelli (sometimes only one and a half times 

 as far removed from each other as from eyes) and the punctate 

 pronotum will serve to separate ^thalotus from Astacops.

" Head with the eyes nearly twice as broad as long, slightly 

 exceeding the shoulder breadth ; ocelli small, about one and a half 

 times as wide apart as from the eyes, middle of front with a flat 

 longitudinal impression which is also present in &. afzelii [the 

 African type] ; pronotum transverse, only slightly narrowed in 

 front, pronotal process very distinctly punctured, also along the 

 front margin of the pronotum, as well as in the depressions of 

 the scutellum, there are a few fine punctures; corium between 

 the ridges very finely and closely coriaceous ; membrane not
