pubescence ; it has usually been regarded as confined to the north, where 

 it has occurred rarely in the Tweed, Clyde, and Argyle districts of 

 Scotland, but I have a record from Mr. Champion of its occurrence at 

 Deal. 



EMUS, Curtis. 



This genus contains three or four species, one occurring in New 

 Guinea and another in Sumatra ; our single species is extremely rare in 

 Britain, and may^be at once known by the peculiar appearance caused by 

 the dense yelloAV and black pile with which it is clothed, which gives it 

 rather the appearance of a large humble bee, especially when flying, 



E. hirtus, L. A large and stout species, densely and rugosely 

 punctured, clothed with thick pilose pubescence, rather dull velvety 

 black, Avith the under side somewhat violaceous, the head, the greater 

 part of thorax, the three last dorsal segments of hind body, and the 

 sides of the fourth and greater part of fifth ventral segments clothed 

 with, very thick golden pile ; the apical portion of the elytra is variegated 

 Avitli ashy pubescence ; head variable in size ; antennae black, rather 

 strongly thickened but not clavate, with joints 6-10 strongly transverse; 

 thorax transverse narrowed behind, thickly and rugoselj'- punctured with 

 the central line raised, and not glabrous as in Creoj^/iilus ; elytra scarcely 

 as long as thorax; hind body feebly rounded at sides; legs black, 

 pubescent. L. 18-24 mm. 



Male Avith head much larger than in female, and with seventh ventral 

 segment of hind body strongly sinuate in middle of apical margin ; 

 posterior trochanters with a strong curved hook, posterior tibiae a little 

 sinuate before apex. 



In or about fresh cow-dung; sometimes on tlie wing; very rare; Sheerness 

 (Hawaid) ; Chatham (Chanej) ; New Forest ((t. Lewis) : in the latter locality it 

 appears to be found at intervals, and probably occurs there every year in small 

 numbers. Curtis records it from the New Forest, Parley Heath, Eeachamwell 

 (Norfolk), Guildford, Coombe Wood (Surrey), and Devonshire. 



XiEISTOTROPKUS, Perty. 



This genus comprises about fourteen species, which are widely dis- 

 tributed, some of them occurring in North America, India, Brazil, Japan, 

 Java, &c. ; there are two British species ; a specimen of the North 

 American L. cingulatus was taken by the Eev. H. Matthews in North 

 Devon in 1874^ but this was evidently an importation, as is remarked 

 by the Eev. A. Matthews, who records it in Ent. Mo. Mag. xiv. 38.
