gium very similar to that of T. angiistipennis, but more enlarged and com- 

 pressed. Ninth tcrgite large, gradually narrowed posteriorly, the caudal margin 

 with a very broad and deep V-shaped notch, the apices of the adjacent lobes 

 bluntly rounded, and each tipped with a small, chitinized tubercle. Ninth 

 plieurite complete, large, the posterior angle produced caudad into a broad, 

 flattened, obtuse chitinized lobe; proximal ventral angles of the pleurite each 

 with a very prominent yellowish fleshy lobe that juts caudad, the apex bifid 

 by a broad notch; outer pleural appendage small, cylindrical to subclavate. 

 with numerous long, pale hairs; inner pleural appendage a large, compressed 

 blade whose apex juts into the notch of the tergite. Ninth sternite with the 

 adjacent margins contiguous, from the opening a long, slender, chitinized nxl 

 and a few long, coarse, yellow hairs protrude. Eighth sternite unarmed, some- 

 what projecting behind. Eighth tergite entirely concealed beneath the seventh 

 tergite. • 



Habitat. — California. 



Holotype. — cf , Foothills of Mount Shasta, California, May 17, 1914. 

 Paratopotypes. — Males with the type, May 16, 17; paratypes two cT's, 

 Yosemite Valley, California, May 22, 1908, fE. T. Cresson, Jr.). 



The type is in the collection of Dr. Dietz; paratypes in the collection of 

 the writer and the American Entomolpgical Society. 



This beautiful, yellow-winged Tipiila is related to 7\ angustipennis Lw. 

 of northern North America, but is abundantly distinct. The type material 

 was very kindly sent me by Dr. Dietz with the indication that it probably 

 represented a new species. The writer could not reconcile the fly with any of 

 the descriptions, and sent the material to Prof. Doane for his opinion and com- 

 parison with his extensive series of Western Tipulas. He also believes the 

 species to be close to T. angustipennis, which is certainh' the case, but the two 

 species show numerous constant differences. Prof. Doane writes that he has 

 a female of this species from the Yosemite Valley. 



NOTES ON PELENOMUS SULCICOLLIS FAHRS. (CURCULIONID.^). 



BY ROBERT MATHESON, ITHACA, N.Y. 



During the past three seasons a small patch of some five or six square yards 

 of fringed loosestrife {Steironema ciliatum (L) Raf.) growing on the bank of a 

 small stream which passes near my house has been badly destroyed by some 

 foliage feeding insect. M\' attention" was attracted to it this season as nearly 

 every plant, and it was almost a pure stand of this species, was practicalh' 

 destroyed, the leaves having been completely riddled, and many of the stalks 

 badly eaten. Previous examinations had shown that a small cof;Sopterous 

 larva was doing the work, l)ut I had not noted them in any considerable num- 

 bers. Late in July (1918) I found numerous small silken cocoons scattered 

 over the under side of the leaves of the loosestrife, and on later examination I 

 found many small snout beetles feeding on the plants. 



As the beetle seemed to be a species about which very little was known, 

 I reared a few of the larva? and made a close examination for the place of egg 

 deposition. My efforts were rewarded and, though rather late in the season, 

 I found all stages of the beetle. The beetle was kindly identified by Mr. C. \V.
