202 FLORIDA HEMIPTERA 



227. Liburnia Weedi Van Duzee. 



At Sanford I took one male and at Crescent City four fe- 

 males of this species. The macropterous female is 5 mm. in 

 length and has the abdomen concolorous with the segments 

 edged with black. In the brachypterous females the tergum is 

 brown with three whitish longitudinal lines, the lateral bordered 

 below with fuscous beyond which are some pale and fuscous 

 markings. This is a large species recognizable by its dark 

 testaceous-brown color and the heavy fuscous nervures toward 

 the apex of the elytra. 



228. Liburnia humilis Van Duzee. 



At Sanford and St. Petersburg I took a series of brachyp- 

 terous males and females and macropterous females. The lat- 

 ter are larger and darker than the types which were from 

 Jamaica. Two small brachypterous females from Estero are 

 considerably paler but I believe they belong here. 



229. Liburnia puella Van Duzee. 



Crescent City and Sevenoaks, not uncommon. This little 

 species seems to be pretty generally distributed in North 

 America and Mr. Kirkaldy has recently reported it from 

 Australia. 



230. Liburnia basivitta n. sp. 



Small; blackish fuscous with a narrow black front and marked with 

 bright fulvous on the base of the abdomen. Length 2 mm.; to tip of the 

 elytra 3 mm. 



Macropterous form: Vertex narrow, nearly square; fovae distinct; med- 

 ian carina prominent over the apex. Front narrow, a little constricted at 

 base; sides nearly rectilinear; carinas strong. Pronotum short; sharply car- 

 inate. Mesonotal carinas distinct, the lateral slightly divergent posteriorly. 

 Pygofers of the male less excavated below than in puella; stiles slender, 

 curved away from one another; but moderately separated. 



Color fuscous brown to black. Front always black with the carinae 

 slenderly brownish; carinas of the vertex and sometimes of the pronotum 

 paler in black specimens. In pale specimens the pronotum is mottled with 

 pale and the cheeks and pleural pieces are brown. Metapleura pale or ful- 

 vous with a large fuscous spot on either side. Legs pale brown. Antennas 

 black; second joint pale except at base. Abdomen dark brown or black, 

 the first dorsal segment fulvous which color sometimes invades the second 

 segment, and beneath there is a fulvous spot on the middle of the first two 

 segments. Elytra whitish hyaline with the nervures fuscous toward their 

 apex, the marginal heavy.
