354 TERTIARY INSECTS OF NORTH AMERICA. 



the width of the thorax and tapers rapidly to a point ; the wings are slender, 

 pupa-form, ovate pads having a subbasal circular macula, a central, longi- 

 tudinal costal striga, and just beyond it a strongly oblique, subtriangular, 

 costal patch, all pallid on a blackish ground ; these do not clearly appear 

 on all specimens. The head is not well preserved on any specimen. The 

 legs are very delicately covered with short and exceedingly fine recumbent 

 hairs, and fringed beneath with an almost equally delicate series of short 

 distant spinules. 



Length of body, 7 mm ; breadth, 1.75 mni ; length of fore femora, 2 mm ; 

 tibiae, 1.6 mm ; tarsi, l.l"" 11 ; middle femora, 4.25-6" ; tibiae, 4 3 mm ; tarsi, 

 2+ nim ; hind femora, 3.5-5.5 mm ; tibiae, 4 mm . 



Florissant. Three specimens, of which one is immature, Nos. 5525, 

 10723, 12782. 



Family REDUVIID^E Stephens. 



This family, to which so considerable a share of our north temperate 

 bugs belongs, is represented in the European Tertiaries by a number of 

 species and genera belonging to no less than five different subfamilies. All 

 the genera are modern types. The Reduviina are the more common, 

 Harpactor having six species at Oeningen and Radoboj, Evagoras one at 

 Oeningen, while species of Reduvius (in a broad sense) are mentioned as 

 occurring at Aix and in amber ; the Piratina are represented by a Pirates 

 at Radoboj ; the Acanthaspidina by a Platymeris in amber ; the Stenopo- 

 dina by two species of Stenopoda at Oeningen, and the Plceariina 'by a 

 Ploiaria said to occur at Aix. 



Curiously enough, the family is very meagerly displayed at present 

 in the American Tertiaries. At my first examination many species were 

 placed here provisionally which a closer study showed to belong elsewhere; 

 and even the " Reduvius" described from the Green River beds belongs, 

 as I have elsewhere shown, rather to the Corizida. There remain only a 

 couple of forms at, Florissant, each known only by a single specimen, to 

 represent this great family. One belongs to the Acanthaspidina, but shows 

 no affinity to the single member of this group known from amber, the other 

 to the Saicina, and both must be referred to extinct genera, in direct and 

 complete opposition to the European Tertiary Reduviidae as we know them 

 to-day.
