82 INSECUTOR INSCITI.^ MENSTRUUS 



lophoventralis Theobald. leucomcres Giles. 



albotaeniatus Theobald. australiensis Theobald. 



pseudotaeniatus Giles. 



The description agrees with my Group II of the New World 

 stock, and undoubtedly it is this as far as the European genicu- 

 latus is concerned. But I think there is some misapprehension 

 or confusion here. The type of Finlaya is poicilia, the male 

 unknown to me ; but I think it is not allied to geniculatus. I 

 have before me Finlaya samoana Griinberg, which proves to 

 be structurally distinct from any New World type. There are 

 no harpagones, but the harpes are drawn out in strap-shaped 

 form with widened membranous tips, thus simulating the struc- 

 ture of the harpagones. I'f this is the case in the other species 

 listed, we have in Finlaya an Old World group, from which 

 triseriatus and geniculatus should be removed. 



Diceromyia Theobald.^ This includes only furcifer Ed- 

 wards and adersi Edwards. The male genitalia are without 

 harpagones and therefore this is an Old World group. I do 

 not perceive any essential distinction from Bcculex, but I 

 know neither of the species in nature. 



Ochlerotatus Arribalzaga. Side piece of the genitalia with 

 basal and apical lobes ; harpagones well developed, the filament 

 flattened. This corresponds to Group I'V of the New World 

 stock. The species are said to be dominant in North America, 

 Europe and, curiously enough, in Australia. The statement 

 is perfectly correct and I have before me an Australian species 

 the genitalia of which have not been previously described.-

 Genitalia. — Side piece over three times as long as wide, grooved within; 

 apical lobe conical, oblique, setose, the sets pointing toward the side piece; basal 

 lobe rounded, prominent, with three short spines toward the dorsal aspect, the 

 central one hooked, and fine setae on the ventral side. Clasp filament slender, 

 moderate, curved at tip, with a long terminal inserted spine and two setae on the 

 outer side before tip. Harpago moderate, slender, the terminal inserted filament 

 longer than the stem, widely angularly expanded in the middle. Harpes conical, 

 moderate, each with a pointed recurved tip. Unci large, columnar, basally sit- 

 uated, the slender tips pointed inward. Basal appendages moderate, with rather 

 irregular tip and about four short setae.
