PLATE CIX. 



This is a grand and very beautiful species of the Libellula tribe, 

 and one moreover of considerable rarity. Mr. Drury presents us 

 with a figure of this insect in the last plate of his concluding volume, 

 informing us at the same time that he had received it from the Bay 

 of Honduras, and that it is an undoubted non-descript. This ob- 

 servation is certainly well-founded ; it had not appeared in any pre- 

 ceding publication, not even in that of Fabricius, who had devoted 

 so much attention to the insects of that Cabinet in particular. 

 Mr. Drury, in the index to the volume in which it is noticed, calls it 

 Libellula Caerulata, but without assigning any specific character to 

 the species. From the MSS. of this entomologist, in our own pos- 

 session, we obtain some further information on the subject than 

 appears in the work ; the insect was numbered 79 in his cabinet^ and 

 has the following observation annexed to it — " Libellula Caerulata — 

 Muskito Shore. Mr. Shakespear, 1779." 



The figure in the annexed plate is copied from the specimen 

 which Mr. Drury mentions. It is considered to the present time, 

 notwithstanding the researches of many travellers in that part of the 

 globe where this specimen was discovered^ as a very scarce insect.
