instance, in some specimens, has the lateral lobe very nearly as in that" 

 genus. Coquilletti has the areas of the cubital forks so simplified that 

 it contains only about four quadrilateral cells at one end. the rest being 

 hyaline without cross \'eins. (rrocil'iH^ in some specimens, has the 

 median carina cristate on the motazone and as high as that of the pro- 

 zone. Each of these, then, has a character bc^longing (l)ut not peculiar) 

 to Conozoa., as I have detined it, but, since they vary independently, 

 each has two characters of Trhnerotroj)!-^ to the one of Conozoa. If 

 these three species, then, should l)e included in ri'>/^a3v>^/, nearly one-half 

 of the characters I ha\'e been al)lc to find to characterize that genus 

 would become nearly useless. If we furthei- take away the characters 

 of C<>vozo(( whicii tli(\v lack, tiic pattern of tegmina and the elongate 

 scutellum, we should have nothing left peculiar to the group but the 

 "lateral carinae well developed" and the "" frontal costa sulcate above 

 the ocellus." But the first group culminates in a species in which the 

 latei-al carina^ of the prozone are completely broken down, so that 

 nothing would be left peculiar to the group but '' frontal costa sul- 

 cate," and this will hardly do to found a genus on. But it would not 

 only be impractical)le to retain these group?^ (and they are too closely 

 related to include oni^ and not the other), but it would be illogical. 

 Te,('(ina and ]nj(illii(i have l)een varying in ditferent directions, and 

 each is much more nearly related to a typical Ti'iiiu'roti'opi^^ like 

 cm'uleipes^ than it is to the other. These groups, then, must be 

 retained in Trhiierotr-(yp!.'<, or at least removed from Conozod, and, 

 while not as distinct as genera should be, they may be considered to 

 form a subgenus.
