stuall, but very prominent rotundato-pyramida! tubercle, deeply and widely 

 furrowed. Eyes rather prominent, about twice as high as broad ; their fore 

 margin straight, hind margin rounded. Maxillary palpi 6-jointed ; the last 

 joint somewhat thickened, about live times as long as broad ; the fifth joint 

 more than twice as long as the sixth, distinctly longer than the fourth, and 

 subeqnal to the third. Pronotum with the fore and hind margins widely 

 rounded ; all the margins, except the hind one, incrassate ; the lower margin 

 of the lateral lobes distinctly convex; the front and hind angles obtuse, 

 rounded. Fore legs moderately long; coxae not spined ; femora beneath 

 flattened, but only feebly sulcate, bearing a few scattered small spinules along 

 the fore lower carina, and armed with a pair of short rigid apical spinules on 

 the upper side; tibiae ."trongly laterally compressed, bearing four rows of 

 spinules, 4-6 spinules in each row, and armed apically with two pairs of spuis 

 (besides one pair of subapical spinules), tlie lower pair being distinctly longer 

 than the lateral pair. Middle femora with about ^ spinules on the inner lower 

 carina and about 8 on the outer lower carina, with a pair of small rigid apical 

 spines on the upper side and with one spine at the base of the inner knee-lobe ; 

 tibiae strongly laterally compressed, with four rows of spinules, 4-8 spinules in 

 each row, and with two pairs of apical spurs (besides one pair of lower sub- 

 apical spurs). Hind femora basally distinctly incrassate, with the apical half 

 strough' attenuate ; about 10 spiiniles along the outer lower carina and about 

 li^ along the inner one; the knee with two short rigid spinules on the upper 

 side and with one spinule at the base of the inner knee-lobe. Hind tibiae with 

 1-3 spinules along both of the lower carinae, and with two rather regular rows 

 of 18-:^0 spinules on the upper side ; the apex with one pair of small lower 

 subapical spinules, one pair of larger upper subapical spinules and two pairs of 

 vspurs ; the upper spurs are more than twdee as long as the lower ones, and 

 distinctly less than half the length of the first tarsal joint, rather thick, 

 straight, with the apices pointed, incurved. All the tarsi strongly laterally 

 compressed; each joint of the hind pair (except the apical) with a flattened 

 space at the apex from bereath. Subgenital plate of $ convex, transverse. 

 Ovipositor inflated basally, almost straight, near the apex somewhat recurved 

 and pointed. Cerci setaceous, reaching the middle of the ovipositor. 



Genotype : Chopardina importata, sp. n. 



This genus is undoubtedly closely related to Gymnoplectron 

 Hutton, of New Zealand, where the group " Dolichopodini " is repre- 

 sented by several genera. It is separable from Gymnoplectron by the 

 fore femora being armed with two apical spinules, and by the unarmed 

 hind tarsi. Cliofardina is related also to the Mediterranean genus 

 Dolicliopoda, the species of Avhich inhabit caves, but differs from it 

 by the spinulose femora. 



ChOPABDINA IMPOBTATA, sp. n. 



2 . Dirty yellowish-brown. Fastigium of the vertex with the median 

 furrow black. Pronotum with the fore and hind margins brown. Abdomen 

 with the hind margins of tergites brown. Legs unicolorous. Length of body 

 17 mm.; pronotum 4-5; fore femora 14 ; middle femora 14-5; hind femora 

 23 ; fore tibiae 15-5 ; middle tibiae lo-o ; hind tibiae 26'o ; ovipositor 13 mm.
