THREE UIVDESCRIBED ERIOPTERINE CRANEFLIES FROM CALIFORNIA (TIPULID.d.
DIPTERA)BY CHARLES P. ALEXANDER
A mhertt, Mas sachusctts

Dasymolophilus subnudusAlexander, sp. n.
Male. Length about 2.5 mm.; wing, 3.2 mn:'.
General coloration of virtually the entire body, including the abdomen and hypopygium, dark brown. Mesonotum dark brown, thescutellum a trifle paler.
Wings longer and narrower than in ursinut, the anal region greatly
reduced; wings tinged with brown, the veins and macrotrichia
darker. Macrotrichia in the cells beyond the cord very sparse, there
being none in the distal half, or more, of cells Rr, R4,M2or Mn, andscarcely any in cells Ro or Mr; basad of the cord there is a sparseline of trichia along the centers of the cells, as in ursinus. Venation:
Cell R, more extensively sessile than in ursinur, the inner end lying
considerablymore proximad than either cell R4 or Ro; cell Mu longer
and narrower, widest near midlength; vein 2nd A relatively short,only about two-fifths the length of vein 1st A, cell Zxd A being very
narrow. In ursinus, vein 2ndu{ is longer, approximately one-half thelength of vein 1st A.
Male hypopygium with the dististyle slightly subterminal in position, long, strongly curved to the acute tip, the basal half moreswollen; before the tip on the concave face with about three small,acute teeth, shorter and less conspicuousthan in ursinus,the longnarrow apex along the outer convex margin with a series of barely
indicated appressed spinula. Besides the long sinuous edeagus,
there is a more dorsal elongate blackened structure that is densely
set along its length with subappressed spinule.

Holotype, 6, Berkeley, California, May 7, lgIS (M. C.
Van Duzee). Paratopotype, a fragmentary male. Type in theVan Duzee collection.
I am much indebted to Mr. Van Duzee for the loan of thisspecimen. The genus Dasymolophilus Goetghebuer is certainly
distinct from A[olophilus, in several respects pointing more
directly to the essentially Australasian genus fo.riocera Skuse.
Besides the genotype, rnurinus Meigen, of Europe, two species
occur in Eastern North America (ursinus Osten Sacken andniphadias Alexander). Still another perfectly typical species,
circumcinctus Meunier, is found in the Baltic Amber. It is still]Iil

f am greatly indebted to professor Cockerell
for this andother material that he. has most kindly sentme in the past.
The only other nearctic species of the subgenus
is slossone
Alexander, ranging from south carolina
southward into theneotropical regions. The present species
differs from all of
the numerous described forms in the unusualdegree of hairi_
ness of the dististyles of the hypopygium.
