344 GNATS OR MOSQUITOES — CHAPTER XIII 



longer than in Panojdites and Culex, being fully one-third a^ 

 long as the proboscis, are shorter than Mucidus, where they are 

 about half its length. In the 3 the palps are exceptionally long 

 and strongly tufted. Arribalzaga describes the $ palp as 

 5-jointed, but personally, I can make out but two joints in 

 addition to the short basal piece, though it is possible that the 

 minute bead-like terminal joint which he figures, may have been 

 broken off, as the specimen I examined was badly rubbed. The 

 posterior transverse vein is placed just internal to the middle, 

 instead of being outside it, as in Mucidus. 



A fair short definition would be : Mosquitoes with shaggy 

 legs, but with smoothly scaled nape and mesonotum ; the males 

 with the palpi longer than, and the females with theirs, about 

 one-third the length of the proboscis ; with marked humeral 

 callosities, and the posterior venule internal to the middle 

 venule. 



All the three known species are from the warmer parts of the 

 American continent. 



Mr. Theobald's modified definition runs as follows : — 

 " Head covered with small broad curved scales and upright forked 

 ones ; meso-thorax with curved scales in the middle with short broad 

 scales laterally ; abdomen with small flat spatulate scales ; antenna; 

 rather short m both sexes, in the S the two last joints elongated as in 

 Culex ; palpi short in the ? , long in the <? , twice as long as the 

 proboscis in the $ , five-jointed, the first two jomts very small, the third 

 nearly as long as the proboscis, slightly enlarged apically ; the fourth 

 and fifth joints thick, the two nearly equalling the third in length ; in the 

 $ the palpi arc also five-jointed, but short, never more than one-half 

 the length of the proboscis ; the first and fifth joints are very small, the 

 third longer than the second, the fourth longer than the third, according 

 to' Desvoidy and Arribalzaga, but I camiot detect the small basal and 

 apical joints myself in either species. The proboscis is short and rather 

 thick. The prothoracic lobes are said to have lateral appendages which 

 protect the stigmata of that segment. Wings with the scales rather long 

 and thin ; first sub-marginal cell sliort, only a little longer than the 

 second posterior cell ; the posterior cross-vein close to the mid cross- 

 vem, but always a little nearer the base of the wing than the mid. Legs 

 with the apices of the femora, tibiiB, and to some extent the first 

 tarsals with long scales ; ungues of the ? all equal, tiiick, with a large 

 distinct tooth to each, in the ^ fore and mid claws unequal, the larger 

 one twice as long as the smaller and with two teeth, the smaller with 

 one tooth ; hind claws equal and single toothed." 



He tabulates the three members of the genus as below : —

scales (7-8 mm.) 1 Ciliata (Fabricius);
