4 DISTRIBUTION AND DISPERSION OF LEPTINOTARSA. 



DATA OF THE DISTRIBUTION.' 



FLAVOPUSTULATA GROUP. 



Leptinotarsa stali Jacoby. 



Known only from the headwaters of the Rio Atoyac and the Rio Coetzala, in the 

 region of the southern escarpment ; recorded from Puebla,* Matamoros de Izucar* (Sall), 

 and Atlixco,* all in the State of Puebla. 



Leptinotarsa evanescens Stal. 



A rare species recorded by Stal from Guatemala and Costa Rica. It has not been 

 recorded since it was first described. Exact localities are not given. 



Leptinotarsa dohrni Jacoby. 



A rare species described from a single specimen collected by Salle at Yoltepec. Sall 

 does not state whether the locality given by him is Yoltepec in the State of Hidalgo or 

 Yoltepec in the State of Oaxaca. In the latter State there are two places of the same 

 name, one in the northern part, 8 miles west of Huajuapan, and another in the south- 

 western part near Istayulta. 



Leptinotarsa belti Jacoby. 



Closely allied to L. flavopustulata and perhaps only a variety of it ; is confined to the 

 Guatemala Plateau and its extension southward into Nicaragua. It is recorded from 

 Chacoj and Panima in Guatemala (Champion), and from the province of Chontalesin 

 Nicaragua (Belt). 



Leptinotarsa flavopustulata Stal. 



Known only from Guatemala, where it is recorded from San Juan in Vera Cruz, and 

 Chacoj (Champion). 



HALDEMANI GROUP. 

 Leptinotarsa dahlbomi Stal. 



A wide-ranging species which has been recorded from the Rio Grande region of Texas 

 southward to Nicaragua. It is known from the following localities : Texas ;* Mexico 

 Yolos, Atlixco,* and Puebla,* in the Stateof Puebla (Salld) ; Yucatan (Pilate); and 

 Nicaragua Chontales and Grenada (Salle), Cuernavaca,* State of Morelos. 



Leptinotarsa hogei Jacoby. 



A curious species known only from one locality. It is clearly a Leptinotarsa , but 

 bears'a striking resemblance to Zygogramma ornata, with which it occurs. (Mexico 

 Cerro de Plumas.*) 



Leptinotarsa haldemani Rogers. 



A highly variable species confined to the southern end of the Mexican basin and the 

 upper portion of the escarpment on the south and west. It is recorded from Ventanas 

 (Forrer), Puebla,* Cuernavaca* (Salle), and Almolonga* 2 (Hoge). I have found it in all 

 stages at Cuernavaca in Morelos, and at Puebla,* Atlixco,* and Matamoros de Izucar * 

 in the State of Puebla. 



Leptinotarsa libatrix Suffr. 



Closely allied to the preceding and almost undistinguishable from it. The two do not 

 occupy the same regions and probably represent geographical races of the same species. 

 It is recorded from the following localities: Mexico Cordoba,* Amatlan,* Jalapa,* and 

 Almolonga,* 2 in the State of Vera Cruz (Salle\ Hoge) ; Xantipa, Mescala,* Savana Grande, 



1 Localities where I have collected or known these species to occur are marked with 

 an asterisk (*). 



3 Probably this locality is in the canton of Jalapa in Vera Cruz.
