shorter (scarcely longer than the minute one which precedes it), in 

 the second articulation of its anterior male tarsi being considerably 

 more elongated (and composed, apparently, of tw.o joints closely 

 soldered together), ia its abdominal segments (or at least the fii'st 

 four) being each of them broadly membraneous along their apical 

 margins, and in the head of its males being not only more dilated 

 and with the eyes larger, but in having also their frontal excavation 

 extremely deep and anomalous, being abruptly terminated (and 

 trisinuated) either behind or before, and furnished in its centre with 

 a curious tubercle, which has somewhat the appearance of having 

 been intended to support an ocellus.

The very remarkable colour of this beautiful insect (the head ! 

 and prothorax being of a clear cherry-red, whilst the elytra and legs 

 are dark cyaneous) will, apart from its structural peculiarities, im- 

 mediately distinguish it from everything else here enumerated. Its 

 legs are extremely long and slender, and its surface is almost gla- 

 brous. I have observed it hitherto only around the Puerto Orotava 

 and Realejo, in the north of Teneriffe, where it is not uncommon 

 during the spring months, making its appearance about the end of 

 February. It is particidarly attached to the flowers of the Physalis 

 aristata ; and indeed I have never observed it, as yet, on any other 

 plant or shrub.
