THE CANADIAN ENTOMOLOGIST. 31 



The length of M. femnr-rnbrinn but thicker bodied. Head rather 

 large with the occiput elevated ; eyes prominent. Vertex very narrow 

 between the eyes ; the fastigium deeply sulcate ; foveola ]jre,-;ent but 

 minute, their outline circular. Frontal ridge rather broad, sulcate at the 

 ocellus, convex between the antenuce, punctate with black depressions 

 along each margin for its full length. Lateral carinte prominent, but little 

 divergent. Pronotum nearly uniform in width, expanding slightly pos- 

 teriorly ; the median carina distinct only on the posterior lobe, and deeply 

 cut by the three transverse sulci ; posterior lobe punctate with dark 

 impressions. Tegmina extending 5 mm. beyond the tip of abdomen ; 

 wings but little shorter. The terminal ventral segment turned up, narrow, 

 acuminate, entire. The anal cerci are strongly bent upward near their 

 middle, and bear on their lower edge a broad, triangular, wing-like 

 expansion, the apex of which is opposite the bend. 



Colour. — Face, occiput, and disk of pronotum a grayish-lilac with 

 numerous fleckings of sooty black. A broad stripe of black starts from 

 the eye and extends back along the upper side of pronotum to the 

 posterior transverse sulcus. Tegmina grayish-olive, marked regularly 

 over almost their entire surface with subquadrate fuscous spots which are 

 much larger than those possessed by femur-rubriim. Wings transpar- 

 ent, tinged with pale yellow on basal third, the veins of apical fourth 

 fuliginous. Three bands of black cross each femur and are alternated 

 with bands of grayish-blue of the same width. Posterior tibiae with the 

 basal third red, the remainder gray with black spines ; knees black ; 

 venter pale yellow, (alcohol changes the black to a reddish-brown, and the 

 grayish hues to a dull yellow). Dimensions : — Length of body, $ 24 

 mm., $ 27 mm.; of tegmina, ^ 20 mm., ^22 mm.; of antennte, $ 

 II mm., $ 12 mm.; of posterior femora, $ 14 mm., % 15 mm. 



The peculiar mottled appearance, and the broad expansion of the 

 anal cerci of the $ , serve to distinguish this species from all other 

 Melaiiopli of the E. U. S. 

 4. Pezotettix hoosieri, nov. sp. 



Antennae of $ very long, exceeding the length of posterior femora. 

 Vertex between the eyes narrow, scarcely as broad as the basal joint of 

 antennae, (broader in the 9 )> expanding and prominent in front of the 

 eyes where it is broadly but shallowly sulcate ; foveola about twice as long 

 as wide, slightly narrowed in front, more prominent in the 9 • Frontal 

 ridge rather broad, regular, scarcely if at all sulcate below the ocellus ;
