THE CRANE-Fiirs or New York — Part II 987 
The larvae and the pupae of Ctenophora apicata that were described 
by Johannsen (1910) have been studied by the writer in the collection 
of the Maine Agricultural Experiment Station. They were collected at 
Orono, Maine, on June 23, 1909, by Dr. William C. Woods. In 1913 
the writer examined the stump from which they were taken, and found 
a few cast pupal skins. 
The notes here given are taken partly from Dr. Johannsen’s description 
and partly from the original material. 
Larva.— Length, about 30 mm. 
Color white. Body stout, cylindrical. Antenna cylindrical, with an apical papilla. 
On dorsum of head behind antennae, a slender, flexible spine. Spiracular disk surrounded 
by six lobes, dorsal and lateral pairs slender, finger-like; ventral pair blunt. 
Pupa— Length, 25-27 mm. 
Length of breathing horns, 3 mm. additional. 
Width, d.-s., 5.2 mm. 
Depth, d.-v., 5 mm. 
Pupa somewhat similar to that of Tanyptera, differing as follows: Form stout; abdomen 
a little depressed. Sheaths of maxillary palpi strongly recurved at tips. Pronotal breathing 
horns long and slender. Mesonotum with a prominent tuberculate spine on either side of 
median line. Legs*shert, ending before tip of third abdominal segment; tarsal sheaths ending 
about on a level, or those of hind legs a very little longer. Abdominal segments 5 to 7 with 
six to eight spines. Female cauda with six powerful ventral spines or tubercles and two 
dorsal tubercles on either side. Valves of ovipositor short, tergal valves a little longer than 
sternal valves. 
Nepionotype.— Orono, Maine, July, 1909. 
Neanotype.— Orono, Maine, July, 1909. 
Paratypes—— Numerous pupae in collection of Maine Agricultural Experiment Station.

Dictenidia is a genus of Palaearctic crane-flies including three species, 
of which one is European and the others are Japanese. The genotype, 
Dictendia bimaculata Brullé, is very well known. The immature stages 
are described or mentioned by Bouché (1834), by Zetterstedt (1851), by 
Weyenbergh (1872), by Beling (1873 b), by Czizek (1913), and by cther 
investigators. Beling found the larvae in decaying birch (Betula). He 
describes the larvae as being grayish yellow, with four spiracular lobes. 
The pupal duration is seven days. Osten Sacken (1886:173-175) states 
that he has often found larvae in the wet detritus underneath the bark
