HEMIPTEEA— HETBROPTBRA— COREIDyE. 429 



111 the present species the length varies from 5.5 to 6.5""", the average 

 being about G""". 



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

 served are Nos. 5002, 6652, 6980, 8467, 9276, 9585, 10033, 10263, 11015, 



11212, 13307. 



6. Rhepocoris minima. 



See the proceeding sjiecies 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 

 u^jon. It does not appear, however, that the liemelytra 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. ORTHRIOCORISA gen. nov. (SpOpw?, }c6pi?). 



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

 and apparently near Acestra Dall, 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 antennae, 

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

 the middle of the sides of the head ; antennae 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 subfusiform 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 and a little shorter than the hind femora and tibise 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 tibiae totally unarmed, the femora longer than the 

 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.
