 asymmetrical, spiny and sac -like (Text-fig. 287) ; three left lateral conjunctival appendages 

 as in Text-fig. 287 ; frontal conjunctival appendages with three sclerotized pieces (Text-fig.

$ genitalia : First gonocoxae triangular, apices pointed (Text-fig. 245) ; sixteen pairs of 

 intervalvular sacs (Text-fig. 289) ; spermatheca twisted at apices, with a median flange and a 

 long coiled tube of variable thickness.

The range of this species extends in the west into Sumatra, Thailand and Malaya 

 and in the east into Borneo and the Philippine Islands. It seems to be very common 

 in Borneo. Adults have been collected almost throughout the year. 



It is a completely isolated species in the genus on the basis of the aedeagus. 

 However it is close to L. biguttata Walker in colouration of the hemielytra, but the 

 two can easily be separated from each other by the characters of apical antennal 

 segment, colouration of abdomen and shape of claspers (see above). 



In the original description Herrich Schaffer (1848) stated " M. virescens antennis 

 (articulo 4 basi albo) linea lateralis capitis, angulis posticis thoracis, scutello et 

 elytris intus nigris, tibiis tarsique fuscis (Fig. 864) ". Dr. W. Forster (Zoologische 

 Samlung des Bayerischen Staates) has kindly informed the author that in 1944 the 

 type of Myodochus costalis Herrich Schaffer was destroyed as the result of an air 

 raid, but a number of specimens agreeing with Herrich Schaffer's description and
