Chalcid Monodontomerus. The primary larvae 

 of Meloe sometimes infest these bees. 



Anthophora, Latr. — A genus containing four species in 

 Britain, three of which, A. retusa, pilipes and 

 quadrimaculata, burrow in hard sand, mud banks 

 or mortar of walls, and the fourth, A. furcata, in 

 decayed wood. The two first-named are gre- 

 garious. The earth-burrowing species make 

 large oval cells, which look like rough pebbles 

 externally; inside they are exquisitely finished, 

 almost resembling porcelain. 



These bees again have many enemies, which 

 attack them in various ways, — the allied inqui- 

 line genera Melecta and Ccelioxys, the remarkable 

 Coleopteron Sitaris muralis, Forst., the delicate 

 Dipteron Anthrax, and the little Chalcid Mono- 

 dontomerus nitidus. Sometimes only about half 

 the cells in a colony of Anthophora produce off- 

 spring arriving at maturity. 



A. retusa, Linn. — Haivorthiana, Kirb. — Taken at Hazle- 

 grove, B.C. 



A. pilipes, Fab. — acervorum, Sm. — retusa, Kirb. — Distri- 

 buted widely in the district, and often abundant 

 locally. Sitaris muralis has been taken near 

 its burrows in the valley of the Bollin, 

 J.B.H. 



A. furcata, Panz. — Only single specimens so far recorded, 

 from Chester, E.C.T., and Hooton, R.JNT. It 

 should occur elsewhere in Cheshire, as it is not 

 infrequent in North Wales. 

 Saropoda, Latr. — The quick-flying and shrill-sounding 

 S. bimacidata is the only British species. It 

 forms large colonies in banks and sandy cliffs. 

 Apparently a southern insect, it has not been
