82 I. AHMAD 



$ genitalia : First gonocoxae broad at bases, apices pointed (Text-fig. 244) ; fifteen 

 pairs of intervalvular sacs (Text-fig. 276) ; spermatheca elongated and thin, with a coiled tube 

 and a median flange as in Text-fig. 230. 



Type material. Holotype $, Celebes : Gilolo (Wallace Coll.), B.M.(N.H.). 



Other material. Malaya : 13 $, 14 $ ; Philippine Islands : 4 <$, 2 $ ; Sara- 

 wak : 25 (J, 10 $ ; Celebes : 6 <$, 6 $ ; Halmahera Island : 2 <$, 1 $. 



The range of this species extends in the west into Malaya and in the east as far 

 as Halmahera Island east of the Celebes. This species has also been reported on 

 paddy and on grasses, Panicum barbatum. It seems to be very common in the early 

 part of the year, December, January and February. 



This species is the closest ally of L. costalis (Herrich Schaffer) but can easily be 

 separated from this species by the apical antennal segments, which are pale only 

 at bases (pale both at bases and at apices in costalis), by the dorsum of abdomen which 

 is yellowish brown, unicolourous (posterior one-third black in costalis) and by the 

 short paraclypeae, which are thicker at bases and pointed at apices (cylindrical, 

 pointed and knob-like at apices in costalis) . Its broadly truncated claspers extending 

 well beyond the posterior margin of pygophore and linear spermatheca are its 

 peculiarities. 



Distant synonymized this species with L. costalis (Herrich Schaffer) and conse- 

 quently this species was not included by China (1924) in his key for the Oriental 

 species of Leptocorisa ; but the apical antennal segments, abdominal colour and £ and 

 5 genitalia show it to be distinct (see above).

Characterized by the lateral black line, which is represented by two dots on the 

 posterior sides of head and on the pronotal collar, by the basal antennal segments 

 which are black at apices and by the form of <$ and $ genitalia.
