 GNATHUSA, gen. nov. 



Related to Ocvusa Kr., but with entirely different labrum, 

 mandibles, and ligula: possibly related also to Tricolpochila 

 r.rnb. Winged. 



Labrum strongly transverse, apparently trilohed and on the middle 

 lobe with 3 equidistant teeth. Mandibles extremely long, thin, curved. 

 acutely pointed, sickle-shaped, both with an oblique, sharp, rather 

 long tooth behind the middle, before the tooth crenulated. Inner 

 lobe of the maxillas from apex to middle with comb-like teeth, in 

 basal two-thirds with finer spines: outer lobe at apex membranous, 

 with fine hair-like spines. Maxillary palpi rather long, four-jointed, 

 joint 2 shorter than 3: 3 club-shaped: 4 small, aciculate. Mentum 

 transverse, slightly emarginate. Ligula very short, one-half as long 

 as the first joint of the labial palpi, split in two lobes to the base. 

 Labial palpi moderate: joint 1 the longest and the thickest; 2 very 

 -.hurt, about one-third as long as 1 : 3 about twice as long as 2.

 about half way between the middle coxa: the latter hut little sepa 

 rated. Legs rather short; front tarsi shorter than the tibi;e, joints 

 1-4 gradually slightly decreasing in length, 5 as long as 3 and 4 

 together; middle tarsi shorter than the tibiae, joint 1 longer than 2; 

 2-4 about equal in length : 5 a little longer than 1 and a little 

 longer than 2 and 3 together; hind tarsi shorter than the tibia.-: 

 ioint 1 about as IOIIL: as - and 3 together; 2-4 about equal: 5 about 

 is long as 1.
