150 THE ENTOMOLOGIST. 



Odonata. 



Crocothemis erythrea, Br,, Sympetrum striolatum, Aeschna mixta, 

 Brachytron hafniense, Calopteryx haemorrhoidalis, Lestes barbarus, 

 Sympycna fusca, Pyrrhosoma nymphula, Agrion mercuriale, A. 

 puella. 



All these were taken on a single day at Hyeres Plage, and 

 that only in the afternoon when our time was getting very short. 

 To British collectors it appeared strange to find Sympetrum 

 striolatum and Aeschna mixta in mid May; Sympycna fusca is 

 well known to hibernate, and the single ? found is obviously 

 not freshly emerged. For the identifications I am indebted to- 

 Mr. H. Campion. 



Neuroptera. 



ASCALAPHID^. 



Ascalaphus longicomis (H. and S.B.). 



A. libelluloides (S.B.). 



On this occasion A. longicomis was found only at Hyeres, 

 but it was taken by Mr. Main at Ste Baume in July, 1920. 

 A long search for the larvae under stones at both places (a 

 search encouraged by each of us finding one, and one only), 

 and that in spots where the adults were common, appears to 

 demonstrate that though the larvae may occasionally be 

 found in these situations such are not their usual haunts. 

 Unfortunately, though one of the larvae moulted once, we 

 could not get them to feed properly and both died. 



MYRMELEONID.2B. 



Myrmeleon formicarius (H. and S.B.), larvae only. 



The well-known pits of these insects were found in plenty 

 in both localities, sometimes on sheltered ledges of rock 

 faces, sometimes on open stretches of sand, even on the sea- 

 shore. It is not certain that these were all of one species, 

 as unfortunately the larvae were not kept distinct. The 

 only flies to emerge in August were of this species. 



Palpares libelluloides (H). Larvae only. These were found in 

 some numbers on the landward side of a low ridge of sandhills 

 bordering the sea. They form no pit^iike Myrmeleon, and 

 the only sign of their presence was a few dead beetles and 

 other, insects on the sand. On running the hand over the 

 surface of the sand, immediately beneath which they lie, 

 the larvae, large and small, were easily turned out and 

 discovered. No flies emerged during the summer, and no 

 cocoons were formed, though the larvae fed well until the 

 autumn. During the winter they have been kept in an 

 unheated room and not fed at all. A few have died, but
