NB. Anguitula is not unlike a large Sepsis, in general ap- 

 pearance, but has several peculiarities , not mentioned in M,^ 

 Walker's description. 



Venation. The first vein runs so near the costa , that it is 

 discernible with some difficulty, especially beyond the origin of 

 the third vein, where first vein and costa are in close contact; 

 the second vein also runs closely along the first, as far as the 

 origin of the third vein ; beyond it , there is a very narrow 

 interval between the first and second veins, which represents 

 the marginal cell. Second basal and anal cells long , but nar- 

 row ; the anal cell is square at the end, and not drawn out in 

 a point. 



The head is rounded , the occiput not being distinctly sepa- 

 rated from the front and vertex, but strongly projecting and 

 forming a smooth slope, which meets the long thoracic collum. 

 The lower half of the face projects obliquely , at an angle of 

 45°, forming a smooth slope ; but this projection is solid under- 

 neath and does not correspond to a proportionate enlargement 

 of the oral opening. Proboscis stout, palpi slender. The antennal 

 foveae are far apart, on both sides of this projection, near the 

 orbits. The third antennal joint is three times longer than broad; 

 the arista hairy on both sides. Cheeks very narrow. No bristles 

 at all on the head ; the usual erect bristles on the vertex are 

 replaced by a few hairs , visible only under a strong lens ; a 

 row of small bristlets on the cervix, above the junction with 

 the collum. 



Thorax smooth, withouth bristles ; scutellum with two spines ; 

 metanotum large, convex, coalescent with the lateral callosities, 

 which are separated by indistinct sutures only.
