saddle-shaped, deep-seated, and upturned in the middle, regularly- 

 wide on the sides extending downwards. Mesonotum with the 

 dorsal shield long and narrow, earinate in the middle, with the 

 lateral earinate margins spreading apart posteriorly, wth the 

 seutellum large, triangular, depressed in the middle. Posterior 

 tibiae with a stout spur below the middle, and the principal one at 

 tip thick and long. Wing-covers gradually and almost sym- 

 metrically widening towards the tip, the tip almost bluntly 

 rounded, with the inner arc a little narrower than the outer one ; 

 veins of the middle of apex straight, bounding long and narrow 

 areoles, one on either side of the four middle ones forked, those of 

 the upper extremity curved outwards ; middle longitudinal nerve 

 with two curved forks near its tip. Wings with the veins divided 

 into two short forks at the upper extremity and a longer fork next 

 inward of the former, and with two cross-veins forming a chevron 

 beyond the middle. The abdomen is somewhat prismatic, with the 

 central ridge prominent ; the venter moderately wide and not 

 quite flat. 



COTYLECEPS DECOBATA, Sp. nOV. 



Dull fulvous brown, paler beneath. The cheeks, sides, and 

 summit of the front and middle of the vertex dark piceous. Eyes 

 dark brown. Antennae pale fulvo-testaceous, the basal joint longer 

 than wide. Pronotum and sides and shield of mesonotum fulvous, 

 darker on the sutures and across the base ; the seutellum paler. 

 Eostrum and legs pale testaceous. Wing-covers whitish testaceous, 

 extensively marked with pale smoke-brown ; border of the mem- 

 brane broadly smoke-brown, connected on the lower border with 

 a large interrupted spot which connects on its inner end with 

 broken spots continued across the disk, the apical veins being 

 white break the continuity of the apical border ; field of both 

 corium and membrane sparsely flecked, the three transverse veins 

 of the costal area broadly marked, the inner one connected with a 

 ragged band which nearly crosses the corium ; nodal spot long and 

 darker than the uneven series which forms a sort of loop behind 

 it ; the membrane beyond this point has three united spots 

 anteriorly and a roundish one adjoining the posterior end of the 

 loop next the margin ; \\ings smoky, with the veins darker. 

 Tergum paler at tip and along the lateral submargin. 



Length to tip of abdomen 4 mm.; expanse of wing-covers 

 13 mm. 



This delicate little insect bears some resemblance to some of the 

 more strongly marked Phryganidse of the genus Hydropsyclie. A 

 few specimens were secured at Kingstown and at other points up to 

 an altitude of 500 feet above the sea. 



Amblycbatus, gen. uov. 



Form robust, with depressed abdomen, which is fully one-half 

 wider than the breadth across vertex and eyes. Head broad, almost
