THE CANADIAN ENTOMOLOGIST. 139 



A very pretty and delicate insect. The foliacecus tibiae recall 

 Phyllodifiiis, but the c.irinte of the ))rothorax are straight and the other 

 characters agree with Pissonotiis ; it may deserve to be placed in a new 

 genus, but for the present I prefer to place it in Fissonotus. The species 

 is very easily identified by the white thorax and white margin of the elytra 

 and by the deep shiny black of the rest of the body. Described from a 

 specimen taken by the author at Middletown, N. Y., July ii, 1910. Two 

 other specimens were taken at the same locality July 18 and 21, 19 10. 

 Type in the author's collection. 



Pissonohis binotaitis, n. sp. 



Brachypterous Ç . — Form and general appearance of F. marginatus^ 

 but considerably smaller. 



Eyes oval, deeply indented below to receive the antennae ; colour 

 dark gray, almost black, with a yellow margin ; vertex about as long as 

 wide, very slightly produced before the eyes, anterior margin slightly 

 curved ; carinte all present, very pronounced, posterior foveœ very deep ; 

 colour uniform dark reddish brown. 



Front about one and one-third times as long as broad, widest below 

 the eyes, sides slightly arcuate ; clypeo-frontal suture straight, median and 

 lateral carinas quite prominent, median carina forked just below the apex 

 of the head ; colour uniform reddish brown, except a very narrow band 

 along the clypeo-frontal suture, which is light yellow. 



Clypeus of the form of a truncated triangle ; median carina fairly 

 prominent ; colour black, the black band extending across the anterior 

 coxse. 



Basal segment of the antennae a little less than one-half the length of 

 the second ; the second segment lacks the protuberences so often found ; 

 basal segment reddish brown, second segment light yellow. 



Prothorax a little deeper than the head, caudal margin almost straight, 

 very slightly emarginate on the sides and a suggestion of an emargination 

 in the centre ; median carina very prominent, lateral carira^ strong on 

 proximal two-thirds of the prothorax, fading out before reaching the 

 posterior margin ; colour uniform reddish brown. 



Anterior legs yellow, lineaied with brown ; second and third pairs of 

 legs with yellow coxae, femora and proximal half of tibiae brown, the tibise 

 becoming gradually lighter in colour toward the distal end, the distal end 

 of the tibiae and first two tarsal segments light yellow, almost white ; last 

 tarsal segment dark brown ; tarsal spur rather small, light yellow, almost 

 white.
