506 HEMIPTEROEOGICAE GLEANINGS 



Liburnia tuckeri, n. sp. 



Closely allied to detecta but smaller and with a narrower 



front. Length 2/^> mm. 



Macropterous form ; Vertex short, transverse, not exceeding the eyes, 

 basal fova about twice broader than long; apical small, triangular, little 

 longer than broad at base. Front linear, a little narrowed between the eyes, 

 its apex but feebly emarginate. Clypeus short. Pronotum broad, scarcely 

 longer than the vertex. All the carina; prominent. Elytra short with the 

 nervures indistinct toward the base. Genital segment of the male long 

 cylindrical, the aperature but little oblique ; plates ljgulate, regularly 

 arcuated, nearly in conformity with the aperature of the pygofers. Pygofers 

 of the female short, scarcely exceeding the connexivum, a little narrowed 

 apically. 



Color dull whitish testaceous, or a little tinged with yellow on the 

 scutellum and beneath; slender margins of the carina? on the front and 

 clypeus and sometimes the apical fova of the vertex, eyes, tip of the 

 rostrum, claws, a spot on the metapleura, a point on the apical segment of 

 the connexivum, a cloud on the base of the tergum in the female, blackish. 

 In the male the disk of all the pleural pieces is fuscous and the abdomen 

 is black with the edge of the connexivum and a band near the base of the 

 tergum fulvo-testaeeous. The elytra are whitish hyaline in the female with 

 the nervures darker toward the apex and punctate. In the male they are 

 distinctly clouded within and toward the apex, with the nervures punctate 

 and darker in the clouded portions. 



Described from one male taken by me at St. Petersburg, 

 Fla., in April, 1908, and a female taken by Mr. E. S. Tucker 

 at Piano, Texas, and kindly sent me for study by Prof. Herbert 

 Osborn. Through an unfortunate mixing of my material I 

 redescribed Liburnia detecta as circumcincta in my report on 

 Florida Hemiptera. 



Genus Cercopis Fabr. 



After a careful study of this genus I am forced to the con- 

 clusion that Triecpliora sanguinolenta (Linn.) must be taken as 

 its type. The genus was founded by Fabricius in 1775 (Syst. 

 Ent. , page 688) with nine species of which the first, fenestrata, 

 is a Ricania; of the others sanguinolenta is the second, carni- 

 fex the fourth and spumaria the fifth. In his later works 

 Fabricius did not change the genus except by omitting fenei- 

 trata and adding new forms. Latreille, the next writer to treat 

 of the genus, in 1801 (Hist. Nat. des Crust, et des Ins., in, 

 page 260), gives a description of it and names spumaria as an 

 "example". This Kirkaldy considers as naming the genotype 

 and therefore makes Cercopis replace ApJirophora Germ, on
