 genus do not appear to vary in the shape of the 

 thorax. With respect to the localities of the above 

 genera, Anthia and Thermophila belong to Africa, 

 while Pachymorpha seems peculiar to Asia. A 

 new East Indian species will be figured in the 

 plates of the present number. The Anthiadse I 

 am inclined to think have no intimate relationship 

 with the Helluonidse ; they are connected on one 

 hand with Manticora, and with Cicindela on the 

 other, by means of Graphiptera and Eurymorpha. 

 A singular species of Cicindela, named Ritchii by 

 Mr. Vigors, so closely resembles some of the Gra- 

 phiptera, that at first sight it might be mistaken 

 for one ; Fabricius indeed seems to have been of 

 opinion that these genera were allied; he names 

 one species Cicindeloides. In their habits also they 

 appear to accord. My friend Monsieur Lefebvre, who 

 collected them in Egypt, writes as follows, "Ces
