Paracalocoris colon Say.

(Indiana). 



It is not absolutely certain that the name colon is applied 

 here to the precise form described by Say. For instance, 

 Say describes the second antenna! joint of eolon as "whitish in 

 the middle and for a short space at base, and blackish at tip." 

 As color characters go in Paraealoeoris those of the antennae 

 are perhaps the most constant. Yet in all the specimens, 

 I have examined of what is here accepted as the eolon group, 

 not one agreed with the original description in coloration of 

 the second joint of the antenna. Paraealoeoris miiUisignatiis 

 Renter, however, agrees perfectly in this particular and is the 

 only species having just that coloration. Nevertheless the 

 remainder of the description of eolon does not fit multisignatus , 

 and in particular the conspicuous pale spot invariably present 

 on apical third of scutellum of the latter species is not mentioned. 

 This could hardly be overlooked. In the absence of type 

 specimens, therefore it is best to preserve the names as they are 

 customarily applied. It is possible, futhermore, that a specimen 

 of the typical variety with proper antennal coloration may 

 sometime be found, in which case all doubts will be removed. 



Description of Nymphs. 



Two nymphs evidently of this species, collected at Beltsville, 

 Md., June 9, 1915, on Psedera quinquefolia, W. L. McAfee (M.), 

 may be characterized as follows : 



Length 4-4.5 mm. ; length of thorax .66 mm.; width of thorax: front 

 .703-. 806 mm.; back 1.2mm.; distance from back of thorax to tip of 

 wing pad 1.6 mm. ; length of antennal joints : first 1 mm. ; second, 1.8 mm. ; 

 third .8-1 mm.; fourth .806 mm. 



General color, yellowish green or sordid testaceous, fusco-piceous on 

 tips of wing pads, and sometimes on head. Antenna: first joint light 

 greenish to reddish, with copious black pile; second joint, basal two- 

 fifths, stramineous, remainder reddish, varying to piceous, with copious 

 black pile, more abundant apically; third joint greenish, apical third 

 blackish, also with longer and more copious pile than usual; fourth 

 joint pale. Femora when marked, reddish or fuscous with yellowish 

 spots; tibiae with two dark and two pale annuli; tarsi dark at tip.
