seem to be found south of where the kelp grows. Narragansett Pier, 

 K. I., is my most southern locality. I have seen the kelp a quivering 

 mass of maggots and later an enormous swarm of flies." Length 3 

 to 6 mm., the smaller recorded as 'parvula. Seven specimens of both 

 sexes from European seacoasts are also in the United States National 

 Museum, determined by Collin, Bezzi, and Lundbeck, the two latter 

 having identified it as friglda Fabricius. 



Male. — Head and body black, the antennae, palpi, and proboscis 

 reddish ; a few reddish indistinct marks below wing on pleura ; hind 

 «dges of last three segments and sides of last four yellowish red; 

 abdomen flat, with a single row of bristles on each side and across 

 the hind margin of each segment beyond the first or second (fewer 

 in small specimens) ; front femora thickened and with stout spines, 

 front tibiae spiny, but with some appressed pile on ventral side; 

 front basitarsus with several stout, short erect spines below near base, 

 the apex below with a thin, expanded rim or margin, wider on 

 mesial side. Middle femora and tibiae spiny, the latter villous on 

 fl.exor side and with several stout apical spines ventrally; middle 

 basitarsus with long hair below and behind, and with about four 

 stout spines curved downward on the front side. Hind femora and 

 tibiae somewhat thickened, spiny, the latter with a few more deli- 

 cate hairs on the flexor side ; the yellow brush of cleaning hairs begins 

 below the middle and extends the whole length of the first and second 

 tarsal segments. 



Female. — Abdominal segments less widely bordered with reddish 

 yellow behind, but about the same on the sides. Front femora 

 thickened, but with only a few stout bristles above. 



COELOPA VANDUZEEI Cresson 



Coelopa vanduzeei Cresson, Ent. News, vol. 25, 1914, p. 457. — Peterson, 111. 



Biol. Hon., vol. 3, 1916, No, 2, p. 182 (uumerous morphological figures). 

 Coelopa frigida Cole, First Rept. Laguna Lab., 1912, p. 156 (det. by Aldricb, 



not of Fabricius). — Cole and Lo\'ett, List Dipt, of Oregon, 1921, p. 320. 



Easily recognized by Cresson's description and by the hairs on the 

 first vein; I place the Cole and Lovett Oregon specimens here from 

 the excellent figure, although otherwise it is not known from that 

 State. 



I have before me 119 specimens from the California coast — 

 San Diego (Aldrich), Laguna Beach (Cole), Santa Barbara (Blais- 

 dell, Aldrich) ; Pacific Grove (Aldrich), Santa Cruz (Cole). Adults 

 appear to occur throughout the year, as Doctor Blaisdell sent a large 

 shipment which he collected on January 2, 1929, at Santa Barbara. 

 Professor Hine also sent five specimens of both sexes, which he 

 collected on Kodiak Island, Alaska, in September, 1919.
