and Osten Sacken, and from Volusia (Samuels), Green Cove Springs 

 (Boardman), Appalachicola (Thaxter) and Ft. Capron in April, 

 Messrs. Hubbard and Schwarz, No. 588, and from Cuba (Uhler), in 

 all 5 <?, 5 ?. Some of these specimens I have compared with the 

 types of the Cuban P. opaca Brunn., in Brunner's collection, from 

 which this species is certainly distinct (as Mr. Brunner agrees with 

 me in believing) in its slenderer legs, longer tegmina, and in the 

 absence of certain spines on the hinder abdominal segments. I no- 

 ticed this species in the Berlin Museum, but failed to note from what 

 locality they came. 



Platyzosteria sabaliaxms nov. sp. Head mahogany-brown, 

 growing yellow toward labrum, blotched everywhere with fuscous, 

 and with a pale spot below either antenna; eyes black ; palpi, espec- 

 ially apical joints, more or less infuscated; antennae of the color of 

 the head, growing paler toward the tip, pubescent, though at base 

 but very sparsely, longer than the body. Pronotum longer than half 

 the breadth, well rounded, the sides very delicately marginate, sur- 

 face smooth, black, with the centre of posterior half rufo-castaneous, 

 the sides with a broad yellow band, just avoiding the margin, nar- 

 rowing in front by a broadly rounded excision of its inner border ; the 

 band extends with fully equal breadth upon the mesonotum, and to a 

 greater or less extent on to the metanotum, and is very conspicuous ; 

 on the meso- and metanotum, which are rufo-castaneous, it is broadly 

 margined interiorly with black. Tegmina wholly wanting. Legs 

 moderately stout, profusely and coarsely spined, the cox33 fuscous, 

 blotched with pale yellow, the rest of the legs dark castaneous, some 

 of the tarsal joints partially infuscated. Abdomen dull rufo-casta- 

 neous, very broadly bordered laterally, and more narrowly apically 

 with black, with an almost imperceptible median carina, the lateral 

 edges produced apically to a delicate point, the last three joints with 

 very distant, very brief rufous hairs springing from raised points. 

 Supraanal plate rather deeply and angularly excised, the lateral pro- 

 jections bluntly pointed; cerci depressed and tapering, pointed, twice 

 as long as the supraanal plate. 



Length of body, 20 mm. ; of antennae, 23 mm. ; of pronotum, 6.3 

 mm.; breadth of same, 10.5 mm.; length of hind femora, 6.1 mm. ; of 

 hind tibiae, 7.5 mm. ; of hind tarsi, 5 mm. 



2 cf, Sanford, in tops of the Cabbage Palmetto (Sabal Palmetto) 

 April 6. It is closely allied to P. mysteca Sauss.
