LISPOCEPHALA. 



The species of this anomalous genus were formerly group- 

 ed with Cocnosia to which they bear a striking resemblance 

 in the arrangement of the sterno-pleural setae, setae of the 

 posterior tibiae, wing venation, and in the spotted abdomen. 

 The genus is now placed among the Limnophorinac. ■ The 

 front is broad in both sexes as in Lispa, and the fulcrum ot 

 the hypopygium of the male is directed forward. The spe- 

 cies thus far known to occur in the United States ma)' be 

 separated as follows. 



a. Crossvein not clouded. 



b. Middle tibia with a bristle on the anterior side; costal spine pres- 

 ent; wing with a brownish tinge. Ohio, New Hampshire, 



verna Fabr. 

 bb. Aliddle tibia with no seta on the anterior side; costal spine not 

 distinct. 



c. Wing of the male milky white. Many localities in the United 

 St'&t&s. . . .erythrocera R. D. (= lactcipennis Zett. IV, 1722). 

 cc. Wing of the male grayish hyaline. Massachusetts, 



var. of erythroccra ? 



aa. Crossveins clouded; middle tibia with no seta on the anterior side. 



Orono, Maine alma Meigen, var. palUpalpis Zett. (b). 



There is another lacfeipennis Zett. (I\". 1586), a species 

 not yet recorded from the United States, which should not be 

 confused with L. erythroccra (= lactcipennis Zett., IV. 1722). 

 The former species is now placed in De.viopsis, a Coenosine 

 genus. Specimens of L. alma were taken at Orono, Maine, in 

 October. I have referred these specimens to var. palUpalpis 

 Zett. (b) because the abdomen is but faintly translucent at 

 the base and at the apical margins of the first and second 

 segments. 



Limnophora torreyae J oh. 



In the original description of this species a misprint occurs. 

 The post sutural d.c. setae are four and not three in number. 

 In some specimens the orbits are not quite contiguous, being 

 separated by a slender frontal line. 

 Mydaea pectinata Joh. 



In the original description of this species, fourth line from 

 the top. page 393, substitute for the words "tibia with a row" 

 the words "tibia with an irregular double row."
