at base of 2nd vein, tip of auxiliaiy vein, marginal cross vein, mth a 

 narrow streak from base of 3rd vein along anterior cross vein, base of 

 discal cell and posterior cross vein. Halteres black.

 Hills, 3,500—3,900 ft., vii-17 {Kemp). 



This species is near my longinervis, in which the wings are equally 

 long, but in that species the cells in the apical tliird of the wing are ex- 

 tremely elongated, almost as much so as in Libnotes. When the two 

 species are placed side by side their distinctness is obvious at a glance. 



Limnobia nigrescens, sp. no v. 



(^. Assam. Long, about 4| mm. 



Wholly dull black. Wings dark grey ; auxiliary vein ending half 

 way between base of 2nd vein and marginal cross vein, which latter is 

 at tip of 2nd vein ; anterior cross vein at base of discal cell, distinctly 

 beyond base of 3rd vein ; 2nd and 3rd posterior cells subequal, a httle 

 longer than discal cell ; posterior cross vein a little beyond base of discal 

 cell. Halteres black.

This must be near aterrima, Walk, but in that species the antennae 

 are described as setaceous and the wings are said to be black. In 

 nigrescens the antennal joints are very distinct. There is also apparently 

 a discrepancy in the venation as the figure Walker refers to shows the 2nd 

 vein forked, in which case aterrima cannot be a Limnobia. 



Limnobia punctithorax, sp. nov. 



(^. S. W. India. Long. 5 mm. 



Head brownish-yellow ; eyes nearly contiguous above ; antennae 

 dark brown except the long 1st scapal joint brownish-yellow, the 2nd 

 scapal joint being similar to the 1st flagellar. 



Fig. 1.— Thorax of Limnobia pund Ihorax, sp. nov., side view 



TJiorax rather elongate, brownish-yellow ; pleurae pale yellowish ; 

 two rather large approximately oval blackish spots behind suture ; 

 scutellum blackish with a median pale stripe ; metanotum blackish. 

 A conspicuous feature of this species is the presence of a number of small 

 more or less round black spots on the anterior and lower part of the 

 thorax, situated as follows. Two, almost contiguous, on anterior mar- 

 gin ; a row of four lower ones along prothorax ; one in the small pit
