48 PROCEEDINGS OF THE jSTATIONAL MUSEUM. vol.61. 



Described from one female and three male specimens from the 

 collection of Dr. C. T. Brues, at Harvard University. The type, 

 allotype, and one of the paratypes are in Doctor Brues's collection ; 

 the other paratype is in the United States National Museum. I 

 have also seen one specimen of this species in the Cornell University 

 Collection, labeled " Goldstream to Downy Creek, Selkirk Mts., Br. 

 Col., Aug. 7-11, '05 "; and one in the collection of the Boston Society 

 of Natural History, taken by Mr. C. W. Johnson, on Mount Wash- 

 ington, New Hampshire, at 3,000 feet. 



2. MICROPMTIS RUGOSUS, new species. 



Near coloradensis^ but differs from that species in being somewhat 

 more coarsely sculptured; in lacking the pronounced median facial 

 carina that, in coloradensis^ extends from the antennal fossae to the 

 clypeus ; in the bright testaceous posterior coxae and femora ; and in 

 more or less of the dorsum of the abdomen being reddish-testaceous. 

 Male. — Length 3.5 mm. Face very coarsely regulose without a 

 distinct median longitudinal carina; vertex, temples, and cheeks 

 roughened like the face ; mesoscutum coarsely ruguloso-punctate ; the 

 parapsidal furrows present but poorly defined; scutellum strongly 

 rugulose and dull ; mesopleurae ruguloso-punctate anteriorly and be- 

 low the straight, distinctly crenulate, longitudinal furrow, polished 

 above it; propodeum sloping gradually from base to apex, strongly 

 rugoso-reticulate, and provided with a median longitudinal carina; 

 stigma very short and broad, about as long as the metacarpus ; radius 

 very slightly directed outward, distinctly longer than first intercu- 

 bitus ; inner spur of middle tibiae a little shorter than middle meta- 

 tarsus ; posterior coxae less than half as long as the thorax ; inner spur 

 of posterior tibiae half as long as the posterior metatarsus; abdomen 

 a little shorter than the thorax, depressed; first dorsal abdominal 

 plate parallel-sided, about twice as long as broad, and ruguloso- 

 striate ; second abdominal tergite distinctly striate, and provided with 

 a sharply-margined triangular shield medially, that is broadest at 

 the base of the segment; posteriorly the second tergite is strongly 

 emarginate; remainder of the abdomen smooth and shining. Black; 

 antennae testaceous below, brownish above ; tegulae and wing bases 

 bright testaceous; wings hyaline; costa yellow; stigma entirely 

 brown; legs, including all coxae and tarsi, testaceous; abdomen more 

 or less reddish on the dorsum, especially on the second and third 

 tergites ; basal half of the venter of the abdomen testaceous.
