Rare. Taken on west side of lake iu the liiji;her woodetl parts of thf^ 

 hills 1 )y beatin J? small bushes and shrul )s. The particular host is not known , 

 and nothing is known of the life history of the species. 



Technical description. — A small species, uniform brown in color; crest as high as its length 

 at base; posterior process not reaching apices of tegmina; tegmina smoky hyaline, tips brown. 



Head as wide as long, sculptured, yellowish, irregularly punctate with brown, sparingly 

 pubescent; base strongly sinuate; eyes prominent, brown, reaching bases of humeral angles; 

 ocelli prominent, translucent, nearer to each other than to the eyes; ch'peus extending below 

 inferior margin of face, yellowish, punctured with brown, pubescent. 



Pronotum uniform brown, coarsely punctured; dorsal crest swollen at base, flattened 

 at apex, as high as its length at base, distinctly step-shaped, anterior lobe rounded and 

 projecting forward, posterior lobe sharply angular, two-thirds as high as anterior, both 

 lobes in some cases margined with patches of darker brown; posterior process short, heavy, 

 acute, not reaching apices of tegmina; humeral angles triangular, flattened, blunt. 



Tegmina smoky hyaline, bases dark brown and punctate, tips brown, veins heavy and often 

 punctured along margins. Undersurface of thorax ferruginous, segments margined with 

 paler; abdomen brown. Legs ferruginous; tibiae and tarsi hairy. 



Length 8 mm.; width 4.8 mm. 



The genus Telamonu Fitch 



The genus Telamona is a typical New York genus, erected by Fitch 

 (1851) from forms from this State and containing a large number of species. 



The genus is in great need of revision, practically all the species having 

 been described from pronotal characters which have since been found to 

 vary to such an extent as to make the validity of some species very doubt- 

 ful. From a large amount of material it. has been possible to recognize 

 fifteen species, but a large series of specimens collected in the basin remain
