Stll's figure of the tegmen ( 1866, Hem. Afr., IV, PI. 1, fig. 3) 

 is incorrect, the transverse claval nervure ( by the presence of which 

 the Swedish Master distinguishes this genus and its allies from Dicty- 

 ophara, Germ., etc. ) not being represented. Brongniart (4) has 

 figured beautifully the flight organs in D. liyalinata ( Fabr. ), and a 

 tegmen is also correctly enough represented in Spinola's Monograph 

 ( PI. 13, fig. 3 ), but as both these works will be inaccessible to a large 

 number of workers, the neuration of the tegmina of the allied D. 

 hampsoni, Distant, is portrayed on PI. 2, fig. 1.

The true hyalinata does not apparently occur in Ceylon ; hampsoni 

 is separable at once by the distinctly longer cephalic process.

Head porrect, eight times as long as pronotum ( medianly ), basal 

 third of dorsal part not much narrower than the two eyes together, 

 finely and closely rngulose transversely, carinate medianly and later- 

 allv, the latter sinuate ; somewhat superficially carinate transversely 

 behind the central line of the eyes, the head above behind this 

 carina being produced laterally, and as wide at the base as the anterior 

 margins of the pi'onotu n. At about one-third of its length the head 

 is suddenly contracted, the central carina of the dorsal part becoming 

 quite obsolete on the basal half, i.e., of the contracted portion, and 

 somewhat superficial on the apical half ; the lateral carinas are sub- 

 parallel up to a short space from the apex, when they suddenly diverge
