CICADELLINAE : PART I. PROCONIINI 195 



includes a color description of the adult, color and biometrical de- 

 scriptions of the nymphs, distributional data, overwintering data, 

 seasonal host plants, mating period, oviposition habits, feeding habits 

 and parasite relationships. They listed a very large number of both 

 woody and herbaceous food plants for H. coagiilata (Say), both monocots 

 and dicots. 



H. insolita (Walker) was found by Turner and Pollard (1959a) to be 

 capable of transmitting Phony Peach Disease experimentally, but it 

 was doubtfully an efficient natural vector. These authors discussed 

 the same features in relation to this species as are listed above for 

 H. coagulata (Say). It is interesting to note that this species differs drasti- 

 cally from H. coagulata (Say) in food plants, being limited largely to 

 Gramineae, and in its flight habits, seldom flying more than two feet 

 above the ground. These drastic differences parallel the morphological 

 differences found during the present study in the structure of the 

 aedeagus, which is quite different in H. insolita from the other species 

 of Homalodisca. In addition to the food plants of H. insolita listed by 

 Turner and Pollard, this species had been collected in numbers on 

 Panicum dichotomojlorum Michaux in Leesburg, Florida, by Warren 

 Adlerz, and from P. maximum Jacquin in Costa Rica. Pollard has 

 described (1965a) the stages of H. insolita and (1965b) its fecundity. 

 H. noressa, new species has been collected from cotton and oleander 

 in Venezuela, but there is no indication that it is a pest species. H. 

 hambletoni, new species has been collected on Agave in Yucatan. H. 

 ichthyocephala (Signoret) has been collected on cantaloupe. H. apicalis 

 Schmidt has been collected on apple, orange, and quince. 



H. ignota Melichar was described from a distorted female, of which 

 the asymmetrical sternal abdominal VII is here illustrated (fig. 189). 

 In addition to the synonymy indicated in the check list there seems 

 a good possibility that H. nitida (Signoret) should preempt H. apicalis 

 Schmidt. The male genitalia of the Jectotype of the latter agree well 

 with figure 181. 



Homalodisca lucernaria (Linnaeus) was described from "America." The 

 type has not been seen. Subsequent writers have been in some agree- 

 ment in restricting the locality to the Guianas (Metcalf, 1965a: 504) 

 except Houttyn, whose record from China is surely an error. There is 

 only one common, widespread species of Homalodisca in the Guianas, 

 and this I have interpreted as H. lucernaria (Linnaeus), with the result- 

 ing synonymy in the check list below. 



The commonest and most widespread species in Central America 

 is interpreted here as //. ichthyocephala (Signoret). Some other authors 

 have synonymized the Signoret name with H. triquetra (Fabricius), 

 but Schroder (1957a: 256) removed the Central American species
