NO. :iU41. THE INSECT FAMILY DELPHACIDAE— CRAWFORD. 585 



Male pygofers large, aperture very small, narrow, with a pair of 

 long, slender processes ventrally; margin of apertm'e sinuate, with 

 a prominent fossa ventrally on each side; anal tube large, open below, 

 produced ventrally into two acute teeth; genital styles very slender, 

 scarcely visible below ventral processes of pygofers. 



Redescribed from five males and females from Greensburg, Penn- 

 sylvania ( Wirtner) , and one female from Alabama (Baker) . Reported 

 from Washington, District of Columbia, and New Jersey (Ball). 



PHYLLODINUS KOEBELEI Osbom. 

 Phyllodinus koebelei Osborn '03:46, 100. 

 Very similar in all respects to P. JlaheUatus and reported also from 

 Washington, District of Colmnbia. Probably this is identical with 

 flaheUatus, and I would not hesitate to make it synonymous except 

 for the fact that Osborn mentions the presence of a very indistinct 

 carina between the median frontal carina and the laterals. It was 

 described only a short time aiter flaheUatus, and perhaps Osborn had 

 not been aware of the latter description. For the present it is included 

 in the synopsis, as a distinct species. 

 Locality. — Columbus, Oliio (Osborn). 



PHYLLODINUS FUSCUS Osborn. 



Phyllodinus fuscus Osborn '05:46, 100. 



Very similar to the foregoing species, and Osborn states that it 

 may be a variation form of it. Probably both of these should be 

 synonyms oi flaheUatus. 



Locality. — Columbus, Ohio (Osborn). 



PHYLLODINUS NITENS Van Duzee 

 Phyllodinus nilens Van Duzee '07:198. 

 Locality. — Jamaica (Van Duzee). 



LIBURNIELLA, new genus. 



Similar in the general aspect of the individuals to Megamelus; head 

 rather strongly carinate; median carina of frons percurrent to base 

 of vertex unforked except a sHght furcation on vertex, the branches 

 of which diverge sHghtly and very soon reunite, thus enclosing a small 

 areolet on vertex; transverse carinse of vertex wanting, as in Tropi- 

 docepTiala. Antennae rather long. Lateral pronotal carinse usually 

 forked, one branch curving out behind eyes. Elytra maculate. 

 Legs as in Megamelus. 



Type of genus. — Lihurniella ornata Stal. 



This genus is related somewhat to Tropidocephala but is distinct 

 both from that and from Megamelus, also.
