Salius COTESI, sp. nov. (PI. III. f. 3). 



Similar in the colouration of the body to 5. rothneyi^ as 

 also in having in the wings three clouds, but abundantly 

 distinct in structure. The clypeus at the apex is shining, 

 and transverse in the middle ; the elongated ridges above the 

 antennae, so prominent in Rothneyi^ are absent, as is also the 

 shining fovea, but there is a small carina there ; the eyes dis- 

 tinctly diverge beneath ; the ocelli are in a triangle, and closer 

 to each other ; the hinder being separated from the eyes by 

 twice the distance they are from each other ; the median 

 segment at the apex is more abrupt ; the abdomen is longer, 

 being as long as the head and thorax united, and its apical 

 segments are not so thickly haired ; the form of the second 

 cubital cellule is very different ; the first transverse cubital 

 nervure is elbowed at the middle, and bends towards the 

 second, making the top of the cellule there about one-fourth 

 of what it is at the bottom, and about one-third of the length 

 of the top of the third ; at the bottom, the second cubital 

 cellule is about three-fourths of the length of the third ; the 

 second transverse cubital nervure is sharply elbowed at the 

 top, making the cellule much narrower at the top than at 

 the bottom, where it is rounded broadly at the apex, instead 

 of acutely angled as in RotJineyi^ while the cubital nervure 

 terminates completely there ; the first recurrent nervure 

 is received a very little beyond the middle ; the second at a 

 less distance from the transverse cubital nervure than is the 

 first ; the radial nervure becomes elbowed about the basal 

 third (and also more sharply), while in Rothneyi it turns up 

 at the middle of the cellule. 5. cotesi also is larger, being 

 13 mm. in length. The long spur of the hind tibise does 

 not reach the middle of metatarsus ; the tibial spines are 

 shorter and fewer.
