along with a small piece of the right fore wing tip. The type is 
contained in the amber collection of the Institut fur Palaontologie 
und Museum der Humboldt Universitat, Berlin. The specimen 
is in mineral oil in a vial along with its original labels reading 
“Fam. Megaloptera” and “Hemerobius resinatus” in black ink and 
“B-8” in blue ink to which I have added my determination label. 
Paratypes comprise one male and one female in the collection of the 
Museum of Comparative Zoology. 
This species is named in honor of Professor F. M. Carpenter of 
Harvard University, whose concern and efforts, extending over 
many years, are primarily responsible for the development of the 
collection of fossil insects of the Museum of Comparative Zoology. 
Propsychopsis hageni n. sp. 
(%• 11) 
Description. 29 flagellomeres distal to pedicel. Fore wing with 
28 costals proximal to end of vena triplica; 13 branches to Rs (not 
including MA) ; terminal (outer) gradate series interrupted; pat- 
tern indistinct, but consisting at least of faint irrorations. Hind wing 
indistinct. Fore wing length — 12 mm. Male (fig. 11): 9th tergite 
with a pronounced lobe postero-ventrally ; ectoprocts very narrowed 
posteriorly and curving ventro-medially ; mediuncus with a broad 
trapezoidal base from which the remaining portion extends as an 
elongate ligulate structure with a blunt, triangular tip. 
Holotype, male: from the amber collection of the Institut fur 
Palaontologie und Museum der Humboldt Universitat^ Berlin. The 
type specimen is contained in a flat block of dark orange amber and 
is preserved in mineral oil along with labels reading “Fam. Mega- 
loptera” and “Hemerobius resinosus” in black ink and “B-7” in blue 
ink along with my determination label. I have seen no additional 
specimens of this species. 
This species i;s named in honor of Hermann Hagen whose thread 
of life is so richly interwoven with the Neuroptera, the Baltic 
amber, and the Museum of Comparative Zoology. 
Discussion. P. hageni differs strikingly from P. lapicidae in the 
form of the ectoprocts which in lateral view are quite narrow with 
a distinct medioventral curvature in P. hageni in contrast to their 
broader, rounded triangular outline in P. lapicidae. The mediunci 
of the two species are also quite distinct, the tip having a ligulate 
shape, in dorsal view, in P. hageni rather than the produced, tri- 
angular shape seen in P. lapicidae. Comparable differences between
