reddish spot above and near the 

 eye often present. Prothorax al- 

 most as long as broad, with round- 

 ed front angles and sometimes 

 with reddish lateral margins. An- 

 tennae pale, but a little darker 

 towards apex. Claws with rather 

 broad dent-shaped dilatation at base. 

 The specimen from Easter 

 Island is a mature one; with red- 

 dish cheeks, reddish streak along 

 the lateral margins of prothorax, 

 and with a reddish spot on the 

 posterior part of the vertex near the eye. Its antennae are strongly brownish 

 coloured in their apical part. In other respects it agrees very well with con- 

 tinental specimens.

Chrysopa Skottsbergi n. sp. 



Yellowish (greenish in life). Head, palpi, thorax, abdomen and legs 

 yellowish. Antennae at least as long as the forewing, yellowish at base and 

 becoming dark brown towards apex; basal joint rather robust and with a 

 distinct dark brown rectangular spot near tip dorsally. At each side of clypeus 

 an indistinct brownish spot. Prothorax broader than long and with truncate 

 front angles. Abdomen with a rather long, pale pilosity. Claws with a strong 

 dent at base. Wings rather short and broad, and obtuse at apex. Venation 

 pale and with short hairs. Gradate veins 

 and a few crossveins at base in the fore- 

 wings somewhat darker. Pterostigma (espe- 

 cially in the hindwings) large, conspicuous, 

 brownish yellow and opaque. At the 

 origin of Cu in the forewing a small brown- 

 ish spot. My^ and M2 coalesce beyond 

 the first crossvein between Rs and M. 

 Series of gradate veins in the wings %, 

 7? or ^/s. Between R and Rs in the forewing 

 9 — II crossveins, in the hindwing 8 — 10; 

 between Rs and M in forewing 4 crossveins. 

 The space between the two series of gra- 

 date veins in the wings rather broad. 



Length of forewing 10 — 11 mm, that of hindwing 9 — 10 mm. Four speci- 

 mens from Easter Island, June (BacKSTROM leg.). 



The species is easily recognized by its short and broad wings, and by 

 the large and conspicuous pterostigma.
