Three New Hemiptera-Heteroptera from the Miocene 



of Colorado. 



BY G. W. KIRKALDY. 



The following fossils were among some interesting forms 

 sent to me for examination by Prof. Cockerell. I have de- 

 scribed them as well as I found possible, but the more accurate 

 determination of Heteroptera will always, apparently, be diffi- 

 cult, as the characters, upon which modern Hemipterology 

 founds genera and species, are rarely visible in fossils. Two 

 of the following belong to the Cimicidae (or Pentatomidae as 

 some authors persist in misnaming it), and the other to the 

 Reduviidae. 



TELEOCORIS gen nov. 



The general form is very much like that of certain Tessara- 

 tominae (a sub-family very sparsely represented in America), 

 but the head is much larger than anything I know in it ; it 

 seems to come into the tribe Halyini of the Pentatominae, but 

 in the absence of a ventral view, it is not certain. The form of 

 the head, in conjunction with that of the pronotum and scutel- 

 lum, separates the genus from any known to me. 



Elongate oval, the head prominent, longer than its width 

 between the eyes, but it is possible that it is exerted from pres- 

 sure. The central lobe is very slightly longer than the lateral 

 lobes, and converges gradually to the apex where it is acute; 

 the impressed line dividing them extends down as far as the 

 eyes. The lateral lobes are fairly straight, and not much nar- 

 rowed towards the apex. The antennae are inserted just apical 

 of the eyes (which are somewhat remote from the base of the 

 head), the first segment not quite reaching the apex of the 

 head. The pronotitin is slightly more than three times as wide 

 as the base of the head, and a little more than twice as wide as 

 its length, the basal margin slightly roundedly emarginate, the 

 lateral margins rounded, more prominent anteriorly than pos- 

 teriorly, and distinctly laminate. The scutellum extends to 

 half the length of the abdomen ; it is regularly triangular, the 

 hind angles acute, and not at all rounded. The abdomen is
