SUBFAMILY IV. CONOCEP1IALIX.K. 555 



with a dark reddish-brown stripe the width of labrum, starting with mouth 

 and passing upward to vertex, where it narrows to the width of that or- 

 gan; then, broadening on occiput, passes back to front border of pronotum. 

 where it divides into two narrow streaks which enclose a whitish area and 

 extend slightly onto metazona; subgenital plate of male yellow; basal third 

 of ovipositor dark brown, the remainder pale reddish-brown. Fastigium 

 short, feebly ascending, its apical portion slightly wider than base with 

 sides and apex rounded. Pronotum short, metazona but slightly ascending, 

 male, not at all, female; lateral lobes with lower margin feebly sinuate. 

 its hind angle rounded. Tegmina narrow, tapering; slightly shorter than 

 wings and of a delicate texture. Hind femora slender, shorter than the 

 closed tegmina, unarmed beneath or very rarely with one or two spines on 

 the outer carina. Cercus of male longer than subgenital plate, tapering to a 



dull point; its 

 tooth short, erect, 

 with a broad base 

 and very sharp, 

 slightly bent point 

 (Fig. 183, I).)

Iii northern Indiana this graceful and prettily marked species 

 i.s quite common among the rank grasses and sedges growing about 

 the margins of tamarack swamps and lakes, where it reaches ma- 

 turity about July 20th. It occurs also in small numbers about a 

 large marsh in Marion County but has not been taken in the 

 southern part of the State. 



R. & H. (1915a, 00) have restored the 0. coiiciiiiiinii of Scudder 

 as a valid species and have made my indiancnsc (lS!:>c, MO) and 

 six other forms synonyms of it. They are probably correct as re- 

 gards intlianense, although Scudder gave an opinion that it Avas 

 a new form before it was originally described. In his later writ- 

 ings Scudder regarded his conHnnnin as a synonym of lu-rlmcrum 

 Serv. (1839, 524), a name which R. & H. have placed with a ques- 

 tion mark under their 0. fhlicuiiiuii, adding: ''We have no def- 

 inite proof that herbticcu-in is the same as fidiciniuni and. until 

 we have some positive information of this sort we do not care to 

 replace a well understood name by another of doubtful status." 

 It would have been better if the same course had been followed 

 with 0. agile, glabcrriiiiuni, nifidinn and laticinnJti. 



Scudder's types of conchnnini were from ("ape Cod, Mass., and 

 the species, as determined by R. & H., ranges from southern New
