HEMIPTEKA HETEKOI'TERA COREIDjE. 429 







In the present species the length varies from 5.5 to 6.5 mm , the average 

 being abov.it 6 mm . 



Florissant. About eighty specimens, of which some of the best pre- 

 served are Nos. 5002, 6G52, 6980, 8467, 9276, 9585, 10033, 10263, 11015, 

 11212, 13307. 



5. RlIEPOCORIS MINIMA. 



See the proceeding species for some remarks on this. This small spe- 

 cies appears to be also relatively rather stouter than the others, but other- 

 wise it can hardly be said to differ in any characters which may be seized 

 upon. It does not appear, however, that the hemelytra are so distinctly 

 marked as appears to be ordinarily the case in the others, and this, when 

 better specimens are found, may serve more readily to -distinguish it from 

 them. 



Length, 4.5-5.5""" ; the breadth can not be readily given as all the 

 specimens are preserved upon their side. 



Florissant. Four specimens, Nos. 3854, 6029, 11755, 11763. 



8. ORTIIRIOCORISA gen. nov. (opepw?, wop/?). 



An elegant genus of Micrelytraria, not far removed from Darmistus Stal 

 and apparently near Acestra Uall, from which it differs totally in the form of 

 the front of the head. It is long and slender in form. Head well rounded, 

 a little elongate, the front scarcely produced in advance of the antenna 1 , 

 rounded, or perhaps a little angulate; eyes moderately small, seated in 

 the middle of the sides of the head ; antenna? very long and slender, the 

 first much longer than the head, nearly or quite as long as the thorax, 

 slender on the basal half, gently incrassate and subfusifonn on the apical 

 half; the second and third joints are exceedingly slender, the third as long 

 as the first and slightly enlarged at the extreme truncate tip, the second 

 a little shorter ; unfortunately the fourth joint is not preserved-; if as long 

 as the third joint the whole, would be still considerably shorter than the 

 body ami a little shorter than the hind femora and tibi,-v together. Thorax 

 considerably longer than the head, tapering toward the apex with no lateral 

 spines. Legs long and very slender, the hind femora scarcely incrassated 

 and both they and the tibia- totally unarmed, the femora longer than the 



J J 



tibiae, the latter about as long as head and thorax together; the length of 



the first tarsal joint about equals that of the other two together. 

 A single species is known.
