heavier marking of the vertex and occiput together form a sort of M, the 

 outer lines being heavier), posterior margin of pronotum, tegulce, triangular 

 spot on anterior lobe of mesonotum, posterior and lateral half of lateral 

 lobes of mesonotum and base of scutellum, these form a broad U, to lines 

 on under side of prothorax, broad band on mesepimera, line above 

 posterior coxpe, light yellow ; abdomen, except a black spot on apex of 

 venter around sheath, and sheath, legs from apex of femora^ mandibles, 

 antennae from first to about twelfth joint, rufous. Wings somewhat fuscous, 

 a band from base of stigma across wing to the apex of second discoidal cell 

 and posterior margin fuscous ; nervures brown, stigma at apex and base 

 of costa lighter. 



Habitat. — Florissant, Colo., July 12, 1907. (S. A. Rohwer.) 



This species may easily be separated from the other members of this 

 genus (C Canadensis^ Nort.; C. Quebecensis, Prov., and C. ochreipes. 

 Konow gives ochreipes as a syn. of Canadensis, but I believe it to be 

 distinct) by the triangular and U-shaped spots on upper side of meso- 

 thorax. I have gone through all the descriptions of the N. Am. species 

 of the genus Lyda in the Cressonian sense, and it is none of those, 

 although in coloration it is nearer some species assigned by Konow to 

 other genera than that in which this species is placed. It belongs to the 

 sub-genus Cephaleia^ as given by Konow in the "Genera Insectorum." 



Eniphytiis Giiieitei, n. sp. {^ E. Gillettei, MacG., M.S.).— $. 

 Length about 8 mm. Form similar to E. mellipes. Head smooth, with a 

 few small punctures \ ocellar basin with sloping walls, almost united with 

 the middle fovea, the walls of which are not as sloping ; antennal ridge 

 prominent, extending into clypeus ; clypeus deeply, angularly emarginate, 

 as long as the second joint of antennae ; a furrow from base of each 

 antenna to occiput; a furrow between lateral ocelli ; middle fovea large; 

 four apical joints of antennae constricted at base, third joint a trifle the 

 longest, four and five subequal ; thorax, in general^ punctured like head ; 

 angles of pronotum, scutellum and postscutellum with denser and larger 

 punctures ; lower part of pronotum and a spot on mesepimera at side 

 irregularly roughened ; first joint of tarsi as long or a little longer than 

 2 + 3; inner claw toolh long, making the claws look bifid; transverse 

 radial curved, received in middle of cell ; second recurrent nervure in 

 basal third of second cubital ; lanceolate cell of hind wings shortly 

 petiolate at apex ; abdomen with fine, rather dense punctures ; sheath 

 broad, obtusely pointed at apex above, rounded beneath. Colour black ;
