Length to tip of hemelytra, 5 millimeters. Width of proootiim, 2 milli- 

 meters. 



Inhabits Orange Springs, Florida, collected in June by Miss Modeste 

 Hunter; also Texas, G. W. Belfrage. 



This species closely resembles Issiisiinmaculatus, Fab.; but tlie shape 

 of the front and its carinate lines will at once mark its distinctness. 



TyLANA, Stal. 

 1. T. ustulata. iSTew sp. 



Resembles T. conspersa, Walker, but having the uervures much coarser 

 and densely reticulated near the apex; short and robust; color pale or 

 bright ochreous yellow, clouded with fuscous. Head ochreous, smooth, 

 obsoletely rugulose, the cranium deeply scooped out, much wider than long, 

 bounded each by high ridges, which are much elevated before and behind 

 the eyes, and marked with large black spots; the middle indented, yel- 

 low, each side of it are two broad, irregularly arcuated, black spots, the 

 lateral edge interruptedly piceous ; posterior margin concave, yellow; 

 anterior margin concave, piceous, indented in the middle, slenderly car- 

 inate ; front minutely punctate, the middle longitudinally elevated, and 

 with the central line slenderly carinated, each side of it longitudinally, 

 broadly grooved and carinated, the carinse abbreviated, slightly curving 

 inward at the ends ; the surface irregularly mottled with piceous, the 

 upper angles entirely f>iceous, and below the line of the eyes is a broad 

 piceous baud, which continues along the sides and across the propleura 

 upon the tegulse ; eyes pale brownish, the piece behind them yellow, 

 with two piceous spots ; epistoma piceous beneath, the central carina 

 prominent, blunt, each side of it somewhat ribbed with piceous ; rostrum 

 piceous, pubescent, reaching beyond the middle coxee. Pronotum about 

 one-third as long as its width, dark ochreous, dotted with piceous and 

 yellow, the middle scooped out, minutely scabrous, infuscated, with a 

 fuscous band posteriorly, on which are two indented points, and the 

 anterior submargin fuscous ; mesonotum about half as long as its width, 

 pale, rufo-piceous, more or less yellow each side of the central shield, 

 and with the middle line slender and yellow, the shield minutely scab- 

 rous, impressed around the submargins and behind, the margins cari- 

 nated ; lateral angles infuscated, a little interiorly is a short, blunt carina, 

 and the surface next to the shield depressed. Anterior pleural pieces 

 broadly black above, and a little so beneath ; the sternum yellow. Legs 

 piceous, more or less yellow at base; femora banded thrice with ochreous, 

 the tibise with two ochreous spots on the outer edge; tarsi and the spines

 piceous, inteirrupted with ochreous at base and on the disk, and witli 

 an ochreous dot at the tip of each cross- vein on the costa and tip ; ner- 

 vures from the middle to apex forming a close net- work of mostly pentag- 

 onal areoles. Tergum marked transversely with piceous ; venter dotted 

 and spotted with piceous and black, remotely pubescent. 



Length to tip of hemelytra, 7 millimeters. Width of pronotum, 2| 

 millimeters. 



Inhabits Colorado and Arizona. 



The hemelytra are wider at tip than at base; the costal area is wide ; 

 the cross-nervules of the base slender, less conspicuous than the others, 

 and generally testaceous; and the costal margin is angularly produced 

 before the middle, as usual in this group.
