Anat HETEROMERA. 77 



On flowers, &c. ; occasionally by beating dead twigs ; local, bnt not uncommon 

 in many districts, although, apparently, often overlooked; Darenth Wood, Leith 

 Hill, Mickleham, Cowley ; Portsea ; New Forest; Glanvilles Wootton ; Sutton 

 Park and Solihull. near Birmingham ; Reptoti, Bretby Wood (on wild cherry blossom) ; 

 Dunham Park, Manchester ; Northumberland and Durham district, Wallington and 

 several other localities; Scotland, common in flowers, Solway, Tay, Dee, Moray, and 

 probablv other districts ; it is most likely not uncommon in Ireland, and may be con- 

 sidered to be generally distributed, although somewhat local, throughout the greater 

 part of the kingdom. 



This species much resembles A. frontalis, but may be known by its 

 shorter and stouter moniliform antennae, and evidently stronger sculp- 

 ture, as well as by the straighter and narrower appendages of the third 

 ventral segment in the male. 



A. melanostoma, Costa (monilicornis, Muls. : s.g. Nasipa, 

 Emery). Very like the preceding, but less elongate, and distinguished 

 by having the thorax not or scarcely strigose, and the sculpture of the 

 elytra very obsolete, as well as by the fact that the third ventral seg- 

 ment of the abdomen in the male bears no lacinise, being simple as in 

 the female ; the antenna? are rather stout and moniliform, with the 

 second joint small, and joints 5-10 subtransverse ; the thorax, moreover, 

 is shorter than in A. rujilabris, and has the posterior angles less acute 

 and more nearly right angles ; the formation of the antennae and the 

 absence of ventral appendages in the male will separate it from A. 

 frontalis ; the colour of the legs is somewhat variable ; in the male the 

 fifth ventral segment is split to base, and the anterior tarsi are dilated. 

 L. 2^-3 mm. 



On flowers, &c. ; one specimen in Dr. Power's collection taken at Darenth Wood on 

 Juce 3, 1860; many years ago Mr. Crotch expressed it as his opinion that it would 

 occur in Britain ; it appears to be found in most of the districts of France, and is 

 rare, according to Thomson, in Norway and Sweden ; it is very likely not uncommon 

 in Britain, and may often have been passed over partly through its likeness to 

 A. f runt alls, and partly owing to the difficulty of determination occasioned by the 

 absence of the appendages in male ; the split fifth segment, however, is a good character ; 

 Mr. Crotch considers Thomson's character of the nearly smooth thorax and obsoletelv 

 strigose elytra to require further confirmation, and adds, as an additioual character to 

 separate it from A. rufilabri*, the fact that the first joint of the anterior tarsi is equal 

 to the second, whereas in the last-named species it is much shorter. 



A. Geoffroyi, Mull, (fasciata, Forst.; humeralis, F. ; bigutta/a, 

 Rossi). Elack, with a large bright yellow patch at each shoulder, which 

 varies in size and sometimes covers the greater part of the elytra ; occa- 

 sionally there is a small spot also behind the middle of each elytron ; 

 the pubescence is more scanty than is usually the case in the species 

 belonging to the genus ; antennae long, somewhat thickened towards 

 , apex, not moniliform, black with the base yellow, moiith and palpi 

 yellow ; thorax transverse, very finely sculptured ; elytra very finely and 

 closely strigose transversely ; legs variable, dark or more or less testa- 

 ceous. L. H-3 mm.
