106 Rev. H. S. Gorham's materials for a 



Sec. I. — Claws simple, a luminous spot, or two segments 

 luminous. 



Photuris Jiectica, Fab. Syst. El. ii. 102. 



The species I refer to this is testaceous above, with 

 black head and abdomen, one luminous spot ; the legs, 

 antennae, and three spots on the thorax are also black. This 

 is the only species I have seen at all agreeing with the 

 Fabrician description.' 



Brazil ; coll. Gorham. 



Photuris moesta, Germ. Ins. spec. nov. G5. 



Black, a little shining, lateral margin of elytra termi- 

 nating before the apex, white ; head, crown, and mouth 

 black, yellow below antennce, pleuree of the prothorax and 

 reflexed margin of elytra yellow. One yellow spot on 

 fifth, or middle of fifth, and whole of sixth segment yellow. 

 Pygidium and ventral apex entire, acuminate, in some 

 specimens with one spot, the ventral apex is notched. ? ?

Photuris trlstissima, n. sp. 

 limbata, Dej.? 



Very nearly allied to moesta, and perhaps not distinct ; 

 chiefly distinguished by having the margin pale to the 

 apex, and the suture and lateral margin of the thorax pale. 

 It is duller, and rather fuscous than black. The fifth seg- 

 ment in the S ? is often wholly white as well as the sixth.

 distinct examples of which are biguttata, Dej. 



Photuris fumosa, n. sp. 

 aurita, Dej. 



Oblongo-ovata, nigro-fumosa, opaca, thorace lunari 

 angulis posticis acutis, productis, thorace plagis duabus 

 capite infra oculos, et antennarum articulis tribus subtus 

 pallide flavis.
