232 THE CANADIAN ENTOMOLOGIST. 



Sphccodes ( Sphecodes J liesperellus, n. sj). 



One P, June 5th, 1895, two ^^ 's, no date, Olympia (Kincaid). This 

 was formerly recorded as S. dichrous, or (arvensis), but it is distinct, 

 having a narrower thorax, less punctured abdomen, etc. 



p. — About 2>yi mm. long ; head, thorax and legs black ; mandibles 



with only the faintest red shade towards the apex ; inner tooth of 



mandibles strong ; ridge of labrum broad and low ; antennal joints 3, 4 



and 5 subequal ; flagellum faintly brownish beneath ; face broad, front 



strongly punctured, no tubercle on vertex ; mesothorax shining, with a 

 median impressed line, but no sulcus, punctures distinct but widely 

 sejiarated ; enclosure of metathorax distinct, semilunar, very coarsely 

 reticulated ; tegulse pale brown ; wings rather light fuliginous, stigma and 

 nervures piceous ; abdomen broad, shining, chestnut red, delicately punc- 

 tured, the punctures almost obsolete on middle of first segment ; first 

 segment with basal and median blackish clouds, connected so as to have 

 the form of an hourglass, fifth segment suffused with blackish. 



In S. arvensis the first abdominal segment is uniformly punctured 

 all over the disc, and the mesothorax is more closely punctured. $ 

 ciiaracters as given in the table. The seventh dorsal segment is broadly 

 rounded, and the fourth is broadly red at the apex laterally. The face is 

 cjvered with white hair. The (J is more like that of S. clematidis than 

 that of S. arvensis. 



Sphccodes (Sphecodes) ai'vensiformis, n. sp. 



One p, no date, another June 30, 1896, Olympia (Kincaid). 

 p. — About 10 mm. long, with the colours and appearance oi S. 

 arvensis, but differing as follows : punctures of mesothorax more widely 

 separated ; enclosure of metathorax less defined, with the reticulations 

 smaller ; first recurrent nervure joining second submarginal cell at the 

 beginning of its last third ; abdomen less distinctly punctured, middle of 

 first segment practically impunctate. As in arvensis, the abdomen is all 

 red ; the apical plate is dark and very narrow. The wings are strongly 

 darkened. Ridge of labrum low and broad, its anterior margin straight. 

 Mandibles black, with a dark red spot just before apex. 



The S. arvensis used for comparison is an Illinois specimen from Mr. 

 Robertson. 



P's, 7th June, 1899, Corvallis, Oregon (Cordley).
