406 FAMILY XL — LYCEID^E. 



angles feebly nodulose, disk more sparsely and coarsely punctate than 

 front one. Scutellum with elevated basal portion triangular, very finely 

 and densely punctate and with a vague median impression; apical por- 

 tion coarsely punctate and with a distinct yellow longitudinal carina. 

 Elytra entire, their side margins feebly sinuate, clavus with two regular 

 rows, corium with several irregular rows, of distinct punctures. Under 

 surface with pleura coarsely punctate, abdomen minutely densely punc- 

 tate, very finely pubescent. Length, 2.5 — 3 mm. 



R. P. Park, Fla., Dec. 5 — March 29 ; numerous specimens 

 taken by beating dead leaves of royal palm in the dense ham- 

 mock on Paradise Key ; others by sifting dead leaves from 

 moist ground along roadways. Described from St. Vincent 

 Island, the types taken "while flying at sunset in a forest in 

 April, at an altitude of 1,000 feet." Not before recorded from 

 the United States. 



IX. Ptochiomera Say, 1832, 18; I, 335. 



Small oblong, rarely shining, species having the head wider 

 than long, inserted in thorax to eyes ; antennae with joint one 

 surpassing apex of head, three and four usually thicker than 

 the others; beak reaching middle coxae; pronotum as in key, 

 the front lobe, especially in brachypterous forms, often twice 

 or more the length of hind one ; scutellum longer than wide, 

 its base depressed, disk with a more or less evident premedian 

 transverse subangulate elevation united behind to a median 

 lengthwise carina; elytra as wide as abdomen, in macropterous 

 forms reaching its tip ; front femora armed beneath with sev- 

 eral teeth, the front tibiae of males sometimes with a preapical 

 tooth ; basal joint of hind tarsi subequal to the others united. 

 Ten species are known from North America, six of which occur 

 in the eastern states. 



KEY TO EASTERN SPECIES OF PTOCHIOMERA. 



a. Front lobe of pronotum less than twice the length of hind one; fore 

 tibiae of males unarmed; antenna? devoid of stiff erect hairs. (Sub- 

 genus Ptochiomera Say). 

 b. Third and fourth joints of antennae suddenly much thickened. 

 c. Front lobe of pronotum subcylindrical, much narrower and darker 

 than hind one; carina of scutellum pale, very prominent. 



351. NODOSA. 

 cc. Front lobe of pronotum subquadrate, concolorous with and scarce- 

 ly narrower than hind one; carina of scutellum feeble. 



352. CLAVIGERA. 



66. Third and fourth antennals gradually somewhat stouter, not sud- 

 denly so; carina of scutellum usually concolorous, obtuse.
