Gymnophora. 429 



segments; some of the present tergal piates may be rather small; 

 it is also to be noted that the chitinized tergites are rather weak, and 

 liabel to shrivel in exsiccating. The seventh segment has long hairs 

 roimd the hind margin; at the end there are two styliform lamellæ. 

 Abdomen is almost bare, only at the end of sixth segment in the male 

 small hairs are more visible. Legs rather slender and hind femora in 

 no way dilated; there are no bristles, the legs being clothed only 

 with short hairs; on the posteroventral side of hind tibiæ there are 

 in the basal half curious, a little longer and erect hairs in both sexes; 

 on the posterior side of hind tibiæ, on a little area just at apex, the 

 short hairs are arranged in transverse, comb-like row, and the same 

 is the case with the a little longer hairs on posterior side of hind meta- 

 tarsi; the posterior tibiæ have small apical spurs. Claws and pulvilli 

 small; empodium small, bristle-shaped. Wings somewhat large; 

 costa reaching to or near to the middle, 1 very long in relation to 

 2 -f 3 ; costa without cilia, only with fme and short hairs ; mediastinal 

 vein distinet and somewhat long, but ending free, not or not distinctly 

 uniting with the first vein; third vein forked, fourth vein relatively 

 short, ending long before the apex of the wing; the furcated concave 

 fold between fifth and sixth vein rather conspicuous; alular margin 

 with only some few fine hairs. ^ 



The developmental stages do not seem to be known; Zetterstedt 

 says: "Larvae parasitae in Lepidopteris degere dicuntur", but I do 

 not know what this statement is based upon. 



The species of Gymnophora occur in woods especiålly in humid 

 piaces, and are seen on leaves of bushes and in low herbage; they are 

 also often found on stems of trees. 



This genus stands in several respects somewhat apart; character- 

 istic of it is especiålly the scarcity and weakness of bristles both on 

 head, thorax and legs. The genus was hitherto considered to include 

 only one species, arcuata Meig., with some synonyms, but recently 

 Schmitz has studied it very thoroughly and proved that it includes 

 four well distinguished European species. Here, as was also the case as 

 regards Phora, difficult synonymicai questions arise; I have here 

 quite followed Schmitz in this respect. 



^ Becker says: "der grosse FliigeDappen fehlt, bildet eine grade Begrenzung 

 und tragt keinerlei Borsten." That alula is wanting is the case also in the 

 other genera, and the margin has a few hairs; the "kleiner Fliigellappen" 

 with some hairs mentioned by Becker is a part of the alar squamula and is 

 present also in other genera.
