general aspect of a male Halictus, but the spines on the 

 apical ventral segment at once distinguishes it. 



Mr. J. B. Bridgman, of Norwich, has this season completed 

 his remarkable captures of Macropis labiaia, by securing at 

 last the long-looked'-for female; males he had taken in 1874, 

 and also in 1876; the other sex had not been previously 

 taken in this country. Some forty, or perhaps fifty, years ago 

 Dr. Leach took a male in Devonshire. This remained an 

 unique British specimen in the British Museum colleclion, 

 until Mr. J. Walton found another in the New Forest, 

 twenty, or probably nearly thirty, years afterwards. Several 

 years again elapsed, when another male was taken by 

 Mr. S. Stevens, at Weybridge. No other capture of the 

 species occurred, until Mr. Bridgman found it at Brundall, 

 thirty-two years subsequently. 



I am not aware of any other capture of new or rare 

 Aculeata made during the past season ; but when such as I 

 have recorded are the fruits of a general scarcity of ^cw/erj^a, 

 we may be pardoned if we wish many returns of similar 

 seasons.

Description of the larva of Acidalia incanaria. — 

 The eggs of this species I received in July, 1875, from Mr. 

 Alfred E. Hudd, of Clifton, Bristol. They were globular, 

 and pale straw-colour. On the 29th of the same month they 

 hatched, and the newly-emerged larvae were slender, body 

 dark green, the head brown. They fed on Polygonum 

 aviculnre until autumn, when they hibernated ; still feeding 

 a little, however, on withered dandelion leaves, on mild days 

 all winter. The dandelion leaves had been supplied when 

 the knot-grass failed, and was subsequently their food until 

 their fidl growth. They were spinning up from the middle 

 to towards the end of A])ril. Length about three-quarters of 

 an inch, and of average bulk in proportion. The head has 

 the face flattened, and is notched on the crown. Body 

 tolerably cylindrical, tapering from the 9th segment to the 

 head, which is very small. The segments overlap each 

 other, making the divisions distinct; but there is not the 

 marked difi'erence between the width of the posterior and
