THE LEPTOCORISINAE OF THE WORLD 125 



Hind tibiae, 4-9-6-6 mm., interocellar distance, 0-4-0-5 mm., distance between an ocellus and 

 an eye, 0-7-0-9 mm. 



Body robust. Head pale, with a black spot behind ocelli and one on clypeus at labral base ; 

 distinctly broader than long ; ocelli large, interocellar distance slightly more than half the 

 distance between an ocellus and an eye. Antennae brownish black, with bases of second, third 

 and at least a quarter basal portions of apical segments pale. Rostrum long, reaching hind 

 coxae with third segment shortest. Lateral black line extending from sides of antenniferous 

 tubercle on to anterior one-fourth of propleuron. Pronotal disc posteriorly tinged green, 

 sometimes pale unicoloured, with backward triangular processes on either side, brownish black 

 spots on posterior angles present (Text-fig. 7). Legs with femora pale, tinged with green, 

 apices of femora, entire tibiae and tarsi brownish black. Hemielytra brownish black with pale 

 veins. Abdomen with dorsum yellowish brown, venter pale, unicoloured. Posterior margin of 

 seventh abdominal tergum truncated (Text-fig. 391), medially slightly concave ; pygophore 

 round, with narrow emarginated posterior margin. 



o" genitalia : Claspers strongly curved in middle, apically acutely pointed, with a smaller 

 spine near apices and a larger in middle (Text-fig. 392) ; aedeagus with both (dorsal and ventral) 

 pairs of thecal appendages as in Text-fig. 393 ; lateral appendages asymmetrical (Text-fig. 

 393) ! vesica with a pair of fused supporting appendages. 



$. Very similar to q* in general appearance and measurements ; posterior margin of seventh 

 abdominal sternum emarginate, with a median fold (Text-fig. 394). 



$ genitalia : First gonocoxae large, round at apices with regular external margin (Text- 

 fig. 398) ; three pairs of interval vular sacs (Text-fig. 395) ; spermatheca tubular (Text-fig. 399). 



Type material. Holotype $ of Paryphus tibialis Stal, Brazil : (F. Schlb), Riks- 

 mus. Stockholm ; Mexico : Oaxaca, 1 <$ (Salle), with a label " Leptocorisa geniculata 

 Guerin (M. M. Type) ", Riksmus. Stockholm. 



Other material. Cuba : 2$, 2$ ; Brazil : 3^, 7$ ; Peru : 3^,1$ ; Panama : 

 1 cJ, 1 $ ; Paraguay : i $. 



The range of this species extends in the north into Mexico and in the south into 

 Paraguay. The adults have been collected in March, September, October and 

 November. 



In spite of enquiries at various Italian museums, it has not been possible to trace 

 the type of Leptocorisa geniculata Guerin or Coristenia flavicosta Costa. It is possible 

 that the specimens from the Riksmuseum, Stockholm with labels " Typ " and 

 " Leptocorisa geniculata Guerin " could have been the type. However, although 

 Guerin's original description was based entirely on colour characters, this and the 

 figure make it obvious that the present concept of the species (which is also Stal's) is 

 correct. This view is strengthened by the identification of a few specimens from the 

 type locality (Cuba) as this species. In 1868 Stal synonymized Coristenia Costa, 1863 

 with Lyrnessus Stal, i860. Costa in his original description states " Luteo testacea, 

 punctata, antennis nigris articulis 2 et 3 summa basi, 4 annulo latiore prope basi 

 un albidis. Capitis vitta utrinque laterali, maculaque pone ocellos nigris ; 

 pronote disc postico virescente, punctis, humeralibus nigris, elytrorum corio fusco 

 virescenti venis discoidalibus fulvis, vena juxta marginata conspicua flava ; tibiis 

 tarsique fuscis, illis annulo minuto basi pallido, long. mill. 13 ; lat. mill. 2 \. Patria 

 ? ". This description agrees in all details with that of L. geniculata and as neither 

 the type specimen nor the type locality is known, it is proposed to accept Stal's 

 synonymy.
