Genus ELAUNON, Burr. 



Elauuon, £irrr, (07') p. 123. 

 Forticula, Dohvn, Sciidd. (partim). 

 Sphingolabis, Kirhy (partim). 

 Apterygida, Bonn., Burr (partim). 



Type, SphinrjoJahis h'lpartita, Kirby. 



Body depressed. Abdomen almost parallel-sided ; fourth an- 

 tennal segment transverse ; tarsi short, first segment rather 

 broad, but little longer than the third. Eoi'ceps of S slender. 



Range. India and Africa. 



Owing to the presence of a flattened triangular tooth near the 

 base of the forceps, the single Indian species of this genus has 

 somewhat the appearance of Forficula, but the almost parallel- 

 sided abdomen and short tarsi distinguish it. 



Originally formed for E. hipartita only, the genus should also 

 include the African species E. erijthrocephala and E. honchampsii, 

 formerly ranged in Diaperasticus.

Chestnut and yellow ; slender ; not very hairy. Antennas 

 brown ; fourth segment nearly as long as the third, all cylindrical. 

 Head deep orange, smooth, tumid. Pronotum orange, the sides 

 paler ; truncate anteriorly, rounded posteriorly, sides parallel, 

 rather flattened, about as broad as long. Elytra long, narrow, 

 parallel-sided, smooth, bright straw-yellow, with a narrow in- 

 distinct fuscous band down the suture and costal margin. AVings 

 long, clear yellow. Legs j^ellow, rather short. Abdomen parallel- 

 sided, elongate, reddish chestnut ; lateral tubercles darker, well 

 developed ; finely and densely puuctulate. Last dorsal segment 

 of (5 rectangular, transverse, puuctulate; posterior margin straight, 

 depressed in the middle, with tumid elevation on each side over 

 the roots of the forceps. Penultimate ventral segment of S and $ 

 obtusely convex. Pygidium of S short, blunt. Forceps with 

 branches in the J depressed, elongate, nearly straight, the inner 

 margin near the base itself dilated to form a tooth-like broad 

 triangular projection, the point of which is sometimes acute, 

 sometimes blunt, sometimes truncate ; beyond this projection very 

 slender and elongate, almost straight, gently hooked at the apex ; 

 in § short, simple, straight, contiguous.
