SOME NEW SPECIES OF NEARCTIC TINGIDAE.* 



By Hkrhert Osborn and Carl j. Dkakk. 



In working up the material for the " Tingitoidea of Ohio"t 

 we found a few new forms from other states that were not 

 included as they were not likely to be found in Ohio. Since the 

 publication of this paper, we have received a few^ specimens 

 from other states for identification, including a few new forms. 

 We believe that a description of these forms will prove useful to 

 other workers in this group and in view of this fact we are 

 publishing a description of these new species. 



Acalypta ovata spec. nov. (Fig. 1.) 



With new material received and with specimens already in 

 hand of Acalypta lillianis we have concluded that the supposed 

 dimorphic forms as given by Bueno are not one species, but two 

 distinct forms. The striking differences in the head and anten- 

 nal characters make the association of the two forms unwar- 

 ranted unless it can be definitely proven by mating or reared 

 specimens. We have cf and 9 specimens of the brachypterous 

 form and only 9 specimens of the macropterous form; the 

 short-winged form we describe herein as new. A. ovata can be 

 readily separated from lillianisX (macropterous form) by its 

 longer head and face, the curved basal segment of the antennas, 

 and the much larger and longer processes or tubercles between 

 the eyes and antennae. 



Head long, narrow, armed with two diverging spines; vertex quite 

 long. Rostrum reaching the middle of the first abdominal segment. 

 Antennae moderately long, beset with a few short hairs; first segment 

 considerably swollen, curved; second segment slightly swollen, shorter 

 than the first ; third segment longest, slender, three times the length of 

 the fourth ; fourth segment fusiform, about equal to the first and second

JWestwood in "Introduction to the Modern Classification of Insects," Vol. II, 

 "Generic Synopsis," page 121, gives the generic description of the genus Acalypta 

 as follows: "Prothorax with the sides slightly dilated, 3-carinated; antennae long, 

 clavate, hemelvtra meeting in a straight suture; wings wanting." In the Ohio 

 Biological Survey Bulletin, No. 8, Vol. II, No. 4, p. 220, we slightly amplified 

 Westwood's original generic description so as to include A. lillianis (the long- 

 winged form) and we do not now feel warranted in placing it in another genus. In 

 this species the sutural area is broad and rounded and the inner margins do not 

 meet in a straight suture; true wings are also present.
