no I. AHMAD 



The type of this species could not be examined. According to Horn (1926-28), 

 the Montrousier collection is supposed to be present in Montpellier Museum (Herault) 

 France. M. Jean Claparede, the curator of this museum, wrote saying that there 

 was no insect collection there and he would convey my request to the University of 

 Montpellier, but no further information has been received. 



However two specimens labelled " Leptocorisa bnrmeisteri Montrousier " from 

 New Caledonia and New Hebrides in the collection of the Paris Museum were 

 examined. These represented Leptocorisa acuta (Thunberg). As the title of 

 Montrousier's paper shows, Kanala is in New Caledonia, from where a number of 

 specimens have been identified as Leptocorisa acuta. In the light of original descrip- 

 tion and type locality it becomes certain that this species is a synonym of L. 

 acuta (Thunberg). 



MUTUSCA Stal 

 Mutusca Stal, 1866 : 160, 1873 : 86 



Type-species : Leptocorisa prolixa Stal by monotypy. 



Body linear. Head elongated. Antennae with basal segments swollen throughout their 

 length, in side view wider beyond middle. Rostrum short, nearly reaching second coxae. 

 Pronotum at least twice as long as broad. 



In o\ posterior margin of seventh abdominal tergum produced into a medium rounded process 

 (Text-fig. 355) ; pygophore rounded, claspers curved at apices, curved portion triangular (Text- 

 fig. 357) ; aedeagus with both (dorsal and ventral) pairs of thecal appendages, with a pair of 

 lateral conjunctival appendages, a dorsal membranous with a terminal appendage (Text-fig. 

 356) and a pair of dorso-lateral conjunctival appendages. Frontal or dorsal conjunctival 

 appendages wanting. 



In $, posterior margin of seventh abdominal sternum emarginate, with a short median split 

 and a fold (Text-fig. 368) ; intervalvular sacs absent ; spermatheca rounded, with a small 

 twisted tube but without a median flange (Text-fig. 370). 



This genus can easily be separated from other genera of the tribe by the basal 

 antennal segments, which are swollen throughout their length. 



Key to Species 



1 Basal antennal segment long, at least a third as long again as third segment ; second 

 at least slightly longer than third ; paraclypeae thin and straight (Text-fig. 3) ; 

 usually a faint black median longitudinal line present on abdominal venter. (In o\ 

 pygophore with a concave median posterior margin (Text-fig. 364) ; aedeagus with 

 second left lateral conjunctival appendage represented by scattered spines and 

 first lateral appendage asymmetrical (Text-fig. 366). In $, ninth paratergite 

 narrow and elongated, at least three times as long as broad (Text-fig. 368)) 



prolixa (p. 113) 



- Basal antennal segment comparatively short, only slightly longer than third ; 

 second at least slightly shorter than third ; paraclypeae thick, medially curved 

 and converging at apices (Text-fig. 354) ; faint black line on abdominal venter 

 usually absent. (In 5*, pygophore with a pointed apex (Text-fig. 355) ; aedeagus 

 with second left lateral conjunctival appendages represented by a bunch of spines, 

 all fused together and first lateral appendage symmetrical (Text-fig. 356) ; in $, 

 ninth paratergite broad and comparatively short, about twice as long as broad))
