In the system this little fairy "Erycina ridens" may perhaps come 

 near E. Mantus, Cramer, Pap. Ex. i. 74, pi. 47, f. F. G : the antennae 

 in Mantus are much more slender, especially at the end. 



Hereafter a group may be found resembling this, when perhaps a 

 careful examination of its nervures, head and legs, as well as of the 

 structure and habit of the larva, may mark it out as a subgenus of Ery- 

 cinidae — (Agathina), the type being E. (A.) Margaretta, a name given 

 by me from the French appellation of the daisy or gowan [Bellis pei'- 

 ennis, Lin., Marguerite of the French), the petals of which somewhat 

 resemble in shape the longish white marks on the upper wings of this 

 little butterfly. A daisy growing by the road-side near Whiting Bay, 

 Isle of Arran, in August last, particularly attracted my notice, as it 

 seemed to smile on me as I passed. The beautifully simple lines of 



Charles Lamb, " To Margaret W ." afterwards struck me ; and 



partly in allusion to the name, but chiefly to the petals of Burns' 

 " wee, modest, crimson-tipped flower," I have named this pretty little 

 Honduras Erycina. — Adam White ; August 5, 1842. 



Singiilar case of monstrosity in the Antennae of a Beetle. The 

 figure in the margin represents the 

 head of a Prionidous beetle, closely 

 allied to, if not identical with, the 

 Macrotoma Senegalensis (Prionus 

 Senegalensis, Olivier), in which the 

 antennae are monstrously developed, 

 the elongated third joint being fork- 

 ed and emitting from the end of each 

 "prong" a part of a distinct anten- 

 nule. In one case the third joint is 

 cleft nearly to the base, in the other 

 only at the tip. In Asmuss' ' Mon- 

 strositates Coleopterorum ' this instance would, of course, be arranged 

 in his third division, " monstra per excessum," and under his section 

 C, " Partes supernumerariae antennarum," answering in some respects 

 to the monstrosity he copies from Doumerc of Carabus auratus. In 

 Helops caeruleus, M. Seringe, in a paper read before the Linnean So- 

 ciety of Lyon, pointed out the occurrence of an example with three 

 joints proceeding from the fifth joint of one of the antennae ; but as far 

 as I am aware, no instance has been registered before this, of the 

 existence of monstrosity on both sides, the same joint in both cases 

 being the " freak- originator."
