332 STATES OF INSECTS. 



of some beetles, as Macropus longimanus, Scar abatis longi- 

 manus L., in which they are so long as to make the males, 

 of these individuals rather inconvenient in a cabinet. 

 Amongst British beetles Clytra longimana and Curcuho 

 longimanus Marsh, are also remarkable in this respect. 

 In some other males the middle pair are the longest; as in 

 Anthophora retusa Latr., a kind of wild-bee a . There are 

 two known instances of remarkably long posterior legs in 

 the Capricorn tribe, which I suspect belong to the present 

 head. One is Saperdahirtipes 01iv. b , in which the hind-legs 

 are longer than the whole body, and adorned with a sin- 

 gular tuft of hairs ; and the other a Clytus, I think, which 

 Mr. MacLeay purchased from the late Mr. Marsham's 

 collection, in which the hind-legs are not only very long, 

 but have tarsi convolute, like some antenna?. From ana- 

 logy I should affirm that these were the characters of 

 male insects. 



To come to the parts of legs. Sometimes the coxa of 

 the last mentioned sex are distinguished from those of 

 the female by being armed by a mucro or spine. Thus 

 the male of Megachile Willughbiella, and others of that 

 tribe, have such a spine on the inner sides of the anterior 

 coxa c . The Trochanter also of some differs sexually ; 

 and you will find that the posterior one of the male in 

 Anthidium manicatum is of a different shape from what 

 it is in the female d . In Spkodrus leucopththalmus, one of 

 the beetles called black dors, in one sex the same tro-
