TENILLUS (r«Voj, 'AAr)?), gen. n<.v. 



The length of the beak of this insect suggests at first that it belongs 

 to the C'ureulionidae, but the completely concealed nietasternal epiniera, 

 with the stoutness of the rostrum, indicate pretty clearly that it belongs to 

 the Otiorhyncliidaj. As the thorax shows no signs of po.stocular IoIk's or 

 fimbria-, and the antennal scrobes are lateral and curve down so as to ter- 

 minate beneatli the eye, it clearly belongs in the Brachyderini, but it can 

 not possiblv be refeiTcd to any of our living genera. The head is inoder- 

 atelv long, but the rostrum, a little arcuate, is nearly twice as long as the 

 head and apparently with a pair of sui)erior longitudinal sulci; the eyes 

 are broadly oval and longitudinal. The thorax is tapering without ocular 

 lobes or fimbriae. TJie first and second abdominal segments are subequal 

 and slightly longer than tlie e(|u;d tliinl an<l fourtli, all with di.stiuct and 

 simple sutures, as far as can be seen. Tibi;e a little arcuate, the third 

 tarsal joint apparentlv not wider than the second. It would seem to be not 

 far removed from Trigonoscuta and Calyptillus. 



A single species is known, from Florissant.
