in which nioiiilis occurred commonly, but only when going over some 

 material obtained near East St. Louis was I able to identify Meinert's 

 species, which proves to be Pro ten flics punctipcnnis. A lengthy descrip- 

 tion of the pupa is unnecessary, as the figures present the characters 

 for their differentiation more clearly than a word description could do. 

 Meinert evidently misidentified his specimens — a not uncommon fail- 

 ing with workers in this group. 



Mr. Hart captured at Little Bear Lake, near Grand Junction, 

 Mich., ]\\\y 15, 1914, both sexes of a very dark variety of punctipcn- 

 nis. The ground color of the body is pale brown, the darker por- 

 tions blackish, and the wing-markings dark gray. Tlie male taken at 

 V'ergennes, 111., August 12, 1914, by Mr. Grizzell agrees in color with 

 those taken in other Illinois localities earlier in the year. As I can 

 find no structural differences between the specimens I consider them 

 merely as color varieties of the same species. 



3. Protenthes cueiciformis Linne 



Tipula culiciformis Linn^, Syst. Nat. ed. 12, 1767, p. 978. 



Larva. — Length, 4-5 mm. Pale yellowish buff, with a dark 

 l)rown dorso-central line, which is interrupted anteriorly and poste- 

 riorly, a rather paler latero-dorsal line, and a cross band of same color 

 on each suture, giving the larva a distinctly checkered appearance. 

 Head buff, apices of mandibles and labial plate dark brown. Head 

 about 1.5 times longer than broad, under side as shown in Figure 7, 

 Plate XX\''I. Antennae much shorter than usual in this genus, barely 

 longer than mandible (PI. XXIV, Fig. 3) ; maxillary palpi as in Fig- 

 ure 4; labium often exposed (PI. XXV, Fig. 8), its lateral basal 

 process fringed; hypopharynx brown and usually very distinct, its 

 anterior margin with about eight rounded teeth on each side ; mandible 

 with the apical half forming a sharp slender tooth, the projection at 

 middle of inner surface of mandible pale, toothlike, projecting almost 

 parallel with the apical tooth. Anterior pseudopods with numerous 

 soft yellow hairs at apices, those at center slightly stouter and thorn- 

 like, but not in the form of claws ; abdominal segments with numer- 

 ous very fine hairs on sides, which are only visible under a high-power 

 lens; posterior pseudopods of moderate length, armed at apices with 

 long claws, which are uniformly pale brownish; anal tufts consisting 

 of about ten sensory hairs each, their bases inserted in papillae which 

 are about three times as long as thick. 



Pupa. — Length, 3.5-4 mm. Yellow to pale brown, the abdomen 

 marked somewhat similarly to that of the larva. Thoracic respiratory
