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



emarginate, and the eightli is small and notched in the 

 male, while in the female the seventh is triangular and 

 notched, the fifth and sixth being simple.

Obs. — The colours and patterns of the Lampyridce are 

 repeated so frequently throughout the genera that I shall 

 in general only notice these resemblances briefly. The 

 present species closely assimilates itself to Lucidota hella 

 {ante, p. 18), as well as to two species of Phuturis, described 

 hereafter from the same country. 



Photinus fumigatus, n. sp. 



Fumeo-niger, sub-opacus, thorace luteo, disco nitido 

 nigro, uti'inque miniato, elytris margine laterally obscure 

 brunneis, abdomine toto nigro. ^ , ? . 



Long. lin. 3 — 3^. 



The present begins a series of small species of the 

 group to which nigricans. Say, and minutus, Lee, belong, 

 and which are extremely difficult to separate ; the colour of 

 the thorax and elytra, and of the abdomen, are the best 

 characters at present known to me. This little species has 

 the thorax with the disc rather convex and smooth, not 

 channelled, the sides are rather brightly red, and the 

 margins luteous, including the front. The abdomen is 

 wholly black. 



Zapote ; coll. Godman and Salvin. 



Photinus affinis, n. sp. 



Niger, opaciis, thorace breviori, disco nigro lateribus 

 albis, canaliculato. Abdomine segmentis sexto et septimo 

 (basi fuscis) albis. 



Long. lin. 3 i. ^, ?. 



Rather larger in bulk than fumigatus, of a deeper 

 black colour, the black portion of the disc of the thorax 

 triangular, with its apex near the front margin, and the 

 sides only of the thorax whitish, in some specimens a 

 carmine spot not very brightly developed on each side 

 of the discoidal patch. Abdomen whitish at the apex. 

 Sexual characters as usual, but in the male the sixth 

 segment scarcely emarginate, only sinuate.
