the single specimen, collected in Mexico, show it to be the small 

 est ant-lion fly recorded up to that time. As is well known, 

 however, there is considerable individual variation in size in some 

 species of these insects, and I' have recently studied specimens in 

 the National Museum collection which appear to belong to pyg- 

 mceus, although considerably larger than the type, and as large, 

 or larger, than some other forms recently described.* 



In his " Stray Notes on Myrmeleonidae," Part 3, | Dr. Hagen 

 again alludes to this species, putting it, with a query, in the genus 

 Maracanda of MacLachlan, a genus characterized, as is this spe 

 cies, by absence of tibial spurs. As pointed out in that article, 

 it differs considerably from the other species of Maracanda, and, 

 after examining specimens, I have decided to erect for it a new 

 genus. 



MARACANDULA, new genus. 



Tibae without spurs. Antennae short, almost capitate, slender basally. 

 Palpi short. Basal joint of tarsi as long, or nearly as long, as the three 

 following joints. Wings short, their apices strongly dilated, very ob 

 tusely pointed ; venation simple; radial sector with five or six posterior 

 forks. 



Type. Myrmeleon pygmceus Hagen. 



As the original description is somewhat meagre, it may be well 

 to redescribe the species from the material now available.

Male. Length, 20 mm. ; alar expanse, 38 mm. ; greatest width of an 

 terior wing, 5.6 mm. ; antenna, 2.4 mm. Fuscous and luteous. Pu 

 bescence white and black, rather long and sparse. 



Face flat ; upper part, between and surrounding antennas, piceous, form 

 ing a transverse band. Labrum narrower than clypeus, rather long, free 

 edge rounded and not straight or emarginate in front. Palpi luteous, 

 tinged with piceous, especially dark on apical joints; last joint of max 

 illary palpi narrowed towards tip, of the labial, slender fusiform. Labium, 

 palpigers, mentum and throat, tinged with piceous. Antennae about as 

 long as the distance between their base and articulation of anterior wing, 

 fuscous ; several joints before the club, and a portion of the club itself, 

 pale ; two basal joints piceous, their apices narrowly, and articulation with 

 the head, luteous. Vertex strongly elevated ; the sides, viewed from in
