Tegmina and wings pale hyaline, the venation ochraceous. 

 Tegmina with the transverse veins at the bases of the second 

 and third apical areas darkly infuscated ; the costal membrane 

 ochraceous, with its outer edge fuscous, the postcostal area 

 fuscous. Wings with the margins of the abdominal area 

 narrowly infuscated. 



? . The body above darker in hue than in the male; the 

 spots of the abdomen fused and fasciate-like in appearance 

 and distinctly greyishly tomentose ; anal appendage with two 

 oblique black fascige. 



The rostrum reaches the posterior coxae ; the face is faintly 

 sulcated on its posterior half and is somewhat obscurely 

 transversely striate. 



Long., excl. tegm., (^ ? 37 millim. ; exp. tegm., (^ 100,

Hob. New Caledonia. 



DORACHOSA, gen. nov. 



Head about twice as long as the breadth between the eyes ; 

 the front somewhat broad and prominent ; ocelli about as far 

 apart from the eyes as from each other; lateral margins of 

 the vertex somewhat convex ; eyes very long, directed 

 obliquely backwardly, their inner margins ampliated and 

 laminately produced inwardly. Pronotum rather more than 

 twice as broad as long, the lateral margins straight and trun- 

 cate, the posterior lateral angles moderately ampliated. 

 Mesonotum with the cruciform elevation well developed, with 

 its anterior margin slightly gibbous, and its anterior angles 

 very slender. Tympanal coverings absent, the tympana 

 altogether exposed and uncovered. Face very broad, globose, 

 and prominent. Anterior femora armed beneath with three 

 large spines, one at base, one at centre, and one near apex. 

 Rostrum with the apex rather broad and reaching the inter- 

 mediate coxEe. Opercula very small and slender. Abdomen 

 grooved beneath on each side before the lateral margins. 



Tegmina and wings hyaline. Tegmina with eight apical 

 areas, the ulnar veins well divided, the basal cell much longer 

 than broad and wider at base than at apex ; the interior ulnar 

 area about as broad at base as at apex. Wings with six 

 apical areas. 



This genus is allied to Tibicen^ from which it may at once 

 be distinguished by the remarkable structure of the eyes j 

 the structure of the front and face and the strongly spined 

 anterior femora are also distinctive characters.
