regular rugae on each side of the rather broad mesial furrow, which is 

 deep, with transverse rugae on the side ; posteriorly covered with a net- 

 work of close set distinct punctures, a smooth surface with fine hirsu- 

 ties on the flanks, where is a long oval yellow spot. Costal half of 

 the fore wings clouded, especially towards the 3d costal, where it is 

 violaceous, costal nervure testaceous, including pterostigtna. Legs 

 throughout reddish, including the trochanters and tip of coxae; middle 

 tibiae tipped with yellow, and middle tarsi yellow; hind tarsi fuscous. 

 Abdomen coarsely punctured, segments mesially convex, sutures deeply 

 impressed, with the usual yellow band, of which the basal one is much 

 broader than the others ; tip broad convex, not ridged, surface deeply 

 punctured.

Louisiana, (Coll. Ent. Soc. Phil.). 



Its thickened denticulate antennae, coarsely punctured body, angu- 

 lated clypeus, violaceous dark spot on the sub-costal cells ; the coarsely 

 punctured propodeum, except the small indistinct enclosure, with its 

 regular striae, and the large ovate lanceolate stripes on each side, will 

 readily distinguish this very interesting species. 



Section D. 

 % . Body stout and thick, Monedula-like ; the eyes are much longer 

 and more excavated than usual, front very narrow, much elongated in 

 front of the antennae; clypeus square, as long as broad. Head unusu- 

 ally short, aud vertex high and narrow resembling that of Larra and 

 Monedula; propodeum very short and tumid, broad, basal joint of 

 abdomen unusually broad, resembling Monedula in this respect. Legs 

 long and slender; the 3d sub-costal cell is much elongated. In all 

 these characters the only species of the section yet known to us shows 

 some remarkable affinities to some of the members of the two suc- 

 ceeding families ; this species more strikingly resembling Monedula 

 than any other genus. 



Gorytes moneduloides, n. sp. 



% . Body black, smooth and polished; head with the front depressed 

 below the level of the eyes; ocelli far apart; front very narrow; orbits 

 and supra-clypeal region yellow; clypeus square, yellow, front edge 

 black; labrum of the usual size, but short, testaceous; mandibles red- 

 dish ; eyes very large, slightly indented ; antennae unusually clavate, 

 greatly thickened towards the tip ; scape yellow beneath, tipped with 

 yellow above ; flagellum reddish beneath at base; prothorax with a 

 long broad yellow stripe ; sides of meso-scutum yellow ; a small dot be-
