Mr. C. L. Witiiycombe's Notes on 



Head small, wholly dark fuscous, but with a narrow V-shaped, 

 lighter mark in the centre. Antennae short, about the same length 

 as the head, dark fuscous. The terminal joint is smaller and narrower 

 than the previous joint. Jaws shorter than the head, fuscous, 

 but castaneous at apices. Palpi thicker than antennae. Basal 

 half of palpus white, banded Avith dark fuscous. Terminal joint 

 wholly pale fuscous. Below, the head is white. 



Body creamy-white, with dark brown latero-dorsal bands, most 

 marked in thorax. Prothorax with a pair of latero-dorsal brown 

 bands, in which are imbedded two elongate, dark brown sclerites. 

 Meso- and metathorax with latero-dorsal bands represented by a 

 pair of large spots per segment, in which arc a pair of small dark 

 sclerites. 



In the abdomen the latero-dorsal bands continue, but are less 

 distinct and more broken. In the anterior part of each segment a 

 brottn mark from these extends laterally. A dark median dorsal 

 line runs from the hind part of the thorax along the abdomen. 

 Underside of body mainly v/hite. Legs short, fuscous. 



The larva of Syinpherobius can at once be distinguished 

 from that of Hemerobius, by the short antennae and jaws, 

 and the stout palpi. 



M^inter is passed as a free larva under bark, etc., not 

 within a cocoon. 



Larvae were fed upon Phylloxera jnmctata Licht., and 

 Chionasjns salicis L. upon oak, and probably this is similar 

 to their natural food. The imagines feed greedily upon any 

 aphids, and have thus been kept alive for over two months, 

 during which period many eggs were laid, all fertile. 



Sympherobius elegans Stephens (= striatellus Klap.). 



Wing expanse 10-12 mm. A small daik species with two ladia] 

 sectors in the fore-wings and venation wholly dark fuscous. Some- 

 what resembles Sisyra fnscata and Sy)nj>hcrobius inconspicuus, 

 from both of which it can be separated in possessing two radial 

 sectors.
