172 FLORIDA HEMIPTERA 



90. Ptochiomera antennata n. sp. 



Form of clavigera but with more slender antenme. Castaneous or f us- 

 co-castaneous, very minutely sericeous pubescent on the head, anterior lobe 

 of the pronotum and lower surface ; posterior lobe of the pronotum, scutellum 

 and elytra testaceous or somewhat tinged with castaneous, and coarsely 

 punctured with fuscous ; the punctures on the elytra forming well marked 

 rows along the principal nervures ; five longitudinal vittae on the posterior 

 lobe of the pronotum, the median line of the scutellum, a longitudinal line 

 and two costal spots beyond the middle of the corium, fuscous or blackish ; 

 extreme humeral angles, tip of the scutellum, two marks on the apical 

 margin of the corium and the costa pale or whitish. Membrane slightly 

 infuscated, the nervures paler. Beneath quite uniformly castaneous, a little 

 darkened on the venter, with paler marks about the insertion of the legs and 

 on the stigmata ; the latero-posterior angles or "flaps" of the propleura and 

 metapleura whitish, the former with a fuscous discal mark. Rostrum and 

 legs pale, the femora, especially the anterior, infuscated. Antennae rather 

 short and stout ; basal joint cylindrical, as thick as the third, surpassing the 

 tylus by one half its length ; remaining joints regularly increasing in thick- 

 ness from the slender base of the second ; the apical fusiform, paler beyond 

 its middle, about the length of the second ; third shortest. Length scant 

 3mm. 



Described from one female specimen that I took running 

 on a hot sand bank by the trolley tracks at Tampa, May 2d. 

 Prof. F. H. Snow has sent me for study another female which 

 differs only in being more ferruginous in color. It was taken 

 by him on the Santa Rita Mts. in Arizona at an altitude of 

 5,000 to 8,000 feet. This species is nearest to clavigera Uhler 

 but the length of the antennal joints are different and the apical 

 two are much less thickened. The posterior lobe of the prono- 

 tum is also shorter and the elytral markings are different. 



Family Largidse. 



91. Largus succinctus Linneus. 



Sanford, Sevenoaks and Estero. These specimens vary 

 much in color but all are rather light. The western specimens 

 in my collection are from California and are almost black with 

 the rufous border of the pronotum, elytra and abdomen very 

 conspicuous. 



For some reason I was unable to find a single specimen of 

 Dysdercus in Florida where Mrs. Slosson has taken at least 

 three species.
