VI. New Homoptera Received from the New Mexico Agricultural 

 Experiment Station. — I. 



BY CARL F. BAKER, FORT COLLINS, COLO. 



In several very interesting lots of Honuip- 

 teroiis insects leceived from Prof. T. D. A. 

 Cockerell, of tlie New Mexico Agricnltural 

 College, wei'e included a number of new 

 species in tlie families Fulgoridae, Bytlio- 

 scopidae and fassii.iae. In a series of papers 

 of which this is the first, these species will 

 be characterized, and attention called to 

 their aflfinilies and the localities in which 

 they were taken. 



Thamnotettix lucida, n. sp. — Pale, clear, 

 slightly yellowlNh, green, entirely without 

 markings or dark coloralions. El\ira hya- 

 line. Length male 5.5 mm. 



Fig. I. Thamuoletlix lucida n. sp. A, face; B. dorsum 

 of head and pronotum ; C, spines on inside of hind tibia; 

 D, apex of male abdomen beneath. 



Male. — Face a tenth wider than long; 

 length of clyneus once and two-thirds the 

 width at base, slightly constricted just before 

 b:ise, the basal suture strongly curved; lorae 

 as long as clypens and two-thirds as broad; 

 genae with margin deeply emarginate below 

 eyes, from this to tip of clypens nearly rectili- 

 near, very narrow below the loiae ; front little 



more than one-fourth longer than broad, 

 little less than twice the length of the cly- 

 pens, sides slightly incurved at antenniie, 

 gradually narrowing below. Disc of vertex 

 evenly, slightly convex, with a small de- 

 pressed area on either side near the base and 

 meeting the face at a veiy obtu-e angle; 

 len>;th at middle once ami a half that at the 

 eyes, width between eyes once and five-sev- 

 enlhs the length. Width of pronotum about 

 once and four fifths the length, the length 

 nearly twice that of the vertex, curvature 

 about five-ninths of the length. Scutellum 

 and venation of elytra normal. Spines on 

 in-ide of upper two-thirds of hind tibiae 

 reguhirly arranged and very unusually num- 

 erous. While in mo-t others iheie are but 

 eight m- ten spines in this region, in this 

 species there are about 16. 



Color light green, slightly tinged with 

 yellowish which is more noticeable on tiie 

 abdomen. Last abdominal segment with 

 plate, valves, and pygofers light bluish 

 gieen, the pygofers furnished at lips with 

 numerous strong blunt bristles which are 

 white and conspicuously brown-tipped. 

 Legs pale, some of the spijies brown-tipped. 

 Elytra hyaline, apical areoles somewhat 

 translucent. 



Described from a single male taken at San 

 Augustine (Ckll. 2142). This insect some- 

 what resembles 7: atn'dorsnm in forin but 

 is a very much sm;iller and moie delicate 

 species. It is nearly allied to T. i>ioi?iiita 

 and 7". aureola, but differs must noticeably 

 from those species in being entirely without 

 daik markings. T.Jiiivicaf'ilala is a smaller 

 yellowish and rufous species, with a shorter 

 vertex and smoky elytra. In the arrange- 

 ment of spines on the hind tibiae, T. lucida 

 differs widely from any ThaiTiriOtetti.x I have 

 seen.
