Burnham — Geraridae 
17 
Holotype: USNM 38136. Specimen examined. This specimen 
consists of a prothorax, including spines, and the hindwings which 
overlap one another. Unfortunately, details of the venation are 
incomplete. 
New' material 
FMNH PE 32022. Obverse and reverse halves. The prothorax 
and five spines are preserved in this specimen but unfortunately, due 
to overlap, venational details are obscured. 
FMNH PE 32024. Obverse and reverse halves. The head is well 
preserved, and complete with a compound eye, clypeus, one mandi- 
ble, and a spine base. Parts of all three legs are also preserved. The 
enlarged prothoracic femur is probably an artifact of preservation, 
the result of lateral compression during burial. 
DOES 1. Obverse and reverse halves. This is a somewhat dis- 
torted specimen with the prothorax pushed into the mesothorax. 
Fore and hind wings on the right side are slightly splayed apart and 
reveal most of the venation of the hind wing. 
Wolff 301. Obverse and reverse halves. Only a fragmentary spec- 
imen with a poorly preserved prothorax and spine bases. 
DMRW 2 (Dabasinskas 2). Obverse and reverse halves. An 
excellent specimen showing posterior part of the head, complete 
prothorax (although the spines are broken), mesothorax, meta- 
thorax, and wings, which unfortunately overlap. Its long and 
slender appearance and slim prothorax place it in this species.
