THE CANADIAN ENTOMOLOGIST. 



third joint of maxillary palpi is not swollen, etc. In the absence of black 

 from the abdomen and other characters it resembles H. miniata, King, 

 but the metathorax is blue-black, and all the dark markings of miniata 

 are black, while in grandis they are blue-black. 



Macrophya pulchelliformis, n. sp. — $. Length, 7 mm.; length of 

 anterior wing, 6}i mm. Head narrower than thorax, densely punctured 

 with rather large punctures ; ocelli in almost an equilateral triangle, 

 distance between the lateral ocelli much less than the distance to the 

 nearest eye margin ; third antenn'al joint a little longer than fourth ; eyes 

 distinctly converging, distance between them at the clypeus a little more 

 than the length of the third antennal joint ; clypeus shallowly, squarely 

 emarginate, lobes broad ; mesonotum, scutellum, mesopleura punctured 

 similarly to head ; mesopectus more sparsely punctured ; all tibial spurs 

 simple ; first joint of hind tarsi equal to 2 + 3 + 4 ; claws rather minutely 

 cleft; stigma broad at base, tapering to apex; transverse radial between 

 apex on middle of the cell ; transverse median between middle and base 

 of cell; lanceolate cell contracted ; abdomen minutely punctured. Colour 

 black, subopaque ; clypeus, labrum, spot on mandibles (rest piceous) 

 white ; posterior angles of pronotum, tegulae, small spot on scutellum, 

 stripe on pleura, four anterior legs below apical third of coxae (the four 

 anterior tarsi are somewhat reddish), basal plates, posterior trochanters, 

 femora and tibiae, except at apex, line on outside of posterior coxae, yellow ; 

 apex of abdomen pallid ; wings subhyaline, nervures and stigma brown. 



Habitat. — Lincoln, Nebr., May. Type in the collection of the 

 University of Nebraska. 



This species is nearest pulchella, Klug, but may be known from it by 

 the coxae being largely black and having the posterior femora entirely 

 yellow. 



Macrophya sambuci, n. sp. — 2. Length, 7 mm.; length of anterior 

 wing, 7 mm. Short, robust. Head narrower than thorax, closely, coarsely 

 punctured ; ocelli in a rather low triangle ; distance between the lateral 

 ocelli much less than the distance to the nearest eye margin ; third anten- 

 nal joint longer than fourth ; eyes converging, the distance between them 

 at the clypeus about the same as the length of antennal joints 2 + 3; 

 clypeus with well-separated punctures, rather deeply, squarely emarginate, 

 lobes broad, rounded at apex ; mesonotum and scutellum finely, densely 

 punctured, the sides of the lobes have the punctures larger ; pleura with 

 large, close punctures ; mesopectus with fine, close punctures ; inner spur
