Family MANIDIIDiE 



This family is repre- 

 sented in our fauna by 

 a single, recently discov- 

 ered species, Annrapteryx 

 cremddta, found in Ari- 

 zona. In the genus ylwM- 

 rapteryx the antennae 

 are gradually enlarged 

 toward the tip forming a 

 well-marked club ; the 

 maxillae are well-devel- 

 oped ; the eyes are hairy 

 and overhung by long 

 cilia; and the frenulum 

 is well-developed. 



Our species was de- 

 scribed by Barnes and 

 Lindsey in "Entomo- 

 logical News," vol. 30, 

 p. 245.

 The Dioptids 



The only member of 

 this family that is well 

 known in this country is

 brown insect, with nearly transparent wings (Fig. 836). The veins 

 of the wings are dark, which renders them prominent. In the males 

 there is a yellowish spot just beyond the discal cell. The venation
