A study of the genitalia of a number of species placed in this 

 subfamily, shows it to be a natural group possessing marked struc- 

 tural characteristics as follows. The terminal clasp segment is 

 extremely elongate, slender and arcuate. The harpes are remarka- 

 bly modified in most of the species studied, being approximate, 

 slender and tipped with several divergent, acute spines. This is 

 true of all the species studied except the exceed- 

 ingly peculiar Jamaican Cycloleppteron 

 grabhamii Theo., which diverges remark- 

 ably from other members of the group in its 

 extremely highly specialized ovate wing scales. 

 The Anopheline harpagones are peculiar in 

 being composed of a broad, usually subtrian- 

 gular basal part bearing several stout spines in 

 sharp contradistinction to the characters pre- 

 sented by these organs in the Culicinae. The 

 Jamaican and South American Cellia al- 

 bipes Theo., is another divergent form in that 

 the third longitudinal vein terminates at the cross 

 veins, whereas in other species studied by us it 

 continues beyond. The larva of this form also 

 presents some striking peculiarities, among which 

 may be m.entioned the absence of the slender 

 apical setae on the antennae, though the two stout 

 conic processes are present as in most Anopheline 

 larvae. The larvae as a whole comprise special- 

 ized forms widely divergent from the ordinary 

 culicid type. The yo\ing of this group are easily 

 recognized by the extremely short air tube and 

 the peculiar platelike comb with its posterior fringe 

 of stout sometimes serrulate spines. 



Anopheles punctipennis Say. Genitalia, male 

 Basal clasp segment stout, evenly rounded, apical 

 segment long, slender, arcuate and bearing a small 

 stout spur. Claspette a rather large basal lobe 

 bearing two stout spines, the inner being larger. 

 At the apical third there is another conspicuous 

 stout spine. Harpes slender, fused and tipped 

 with two clusters of about three uneven spines. Harpagones, 

 basal portion subtriangular, apical portion tuberculate and bear- 

 ing several stout, chitinous spines, the two outer being near 

 together ^and larger than the more widely separated, smaller
