Group c. Ochlcrotatus Arribalzaga. 



Section 1. Ochlcrotatus Arribalzaga. 



Section 2. Bcculex Felt. 



Section 3. A'cdimorphtis Theobald. 

 Subgenus 4. A'edes Meigen. 

 Subgenus 5. Skusca Theobald. 



Taking the groups seriatim without regard to the rank 

 assigned : 



Armigeres Theobald. Edwards tabulates 13 species and 

 ligures the genitalia of 4. The harpes and unci are well de- 

 veloped, normal ; no harpagones ; a basal lobe is present, but I 

 cannot tell whether it is a development of the side piece or the 

 basal membrane. I think it is derived independently of the 

 side piece as in the Old World type in general. The clasp 

 filament has generally a whole row of teeth. This is clearly 

 an Old World group. 



Stegomyia Theobald. Five species are here referred to 

 besides the well known argenteus Poiret, namely : 



variegata Doleschal (= scutellaris Walker). 

 albopicta Skuse (= scutellaris Theobald, not Walker). 

 vittata Bigot {= sugeiis Theobald, not Wiedemann). 

 fraseri Edwards. 

 thomsoni Edwards. 



Three of these are before me. Side piece without a basal 

 lobe ; harpes not especially modified ; unci small ; the basal 

 membrane is simple or moderately modified ; clasp filament 

 generally simple, rarely expanded. This is clearly an Old 

 World group. 



Finlaya Theobald. Besides the European geniculatus Olivier, 

 which represents the American triseriatus Say, Edwards lists 

 the following: 



eatoni Edwards. greeni Theobald. 



pulchriventer Giles. notoscriptus Sku.se. 



togoi Theobald. kochi Donovan. 



longipalpis Grtinberg. oreophilus Edwards. 



flavipennis Giles. japonicus Theobald. 



melanopterus Theobald. macfarlanei Edwards. 



trilineatus Theobald. poicilia Theobald. 



niveus Ludlow. guhernatoris Giles.
