PANAMA DERMAPTERA 
A portion of the material here considered, with a few other 
specimens belonging to the National Museum, has recently been 
recorded by Burr (Can. Ent. xlvi, pp. 273 to 276, (1914)). 
We are at a loss to account for the determinations as given by 
that author, unless the names were hastily jotted down and 
the material returned without careful study. We have con- 
sidered the series with the greatest care and have studied all of 
the literature bearing on the species here recorded, as well as their 
allies. The results are convincing that Burr has made the fol- 
lowing misidentifications : 
Material here recorded According to Burr 
Euborellia antoni. Eulabis saramaccensis 
Vostox hrunnei'pennis Vostox insignis (part) 
Prosparatta humilis Vostox insignis (part) 
Prosparatta incerta Purex parvicollis 
Microvostox hilineatus (part) . . . . Spongovostox ghilianii ? 
Labia micans. Labia eqnatoria 
Labia arcuata Prolabia annul ata (part) 
Labia dorsalis Prolahia annulata (part) 
Barygerax esau Prolabia formica (part) 
Eugerax poecilum Prolabia formica (part) 
We have not seen the specimens recorded as Vostox similis, 
Sparatta nigrina and Ancistrog aster variegata. The determina- 
tions are questionable.
