HIPPODAMIA. 55 



3051 b. Hippodamia lengi, new species. 



Distribution: Southern California. 



In the Ulke collection in the Carnegie Museum at Pittsburg, Pennsyl- 

 vania, there are 8 beetles which aside from color-pattern resemble H. 

 apicalis. They are from California and bear a label "var. of H. paren- 

 thesis Horn dix." There is one other of the same kind in the U. S. 

 National Museum from San Diego, California, and one from Southern Cal- 

 ifornia in the Horn collection of the Philadelphia Academy of Natural 

 Sciences. These 10 specimens are decidedly different in their color-pattern 

 from all specimens of H. parenthesis or apicalis that I have seen and should, 

 I believe, be recognized as a species, although it is to be considered as a 

 derivative of H. apicalis. I have designated one of the Pittsburg series 

 as the type. 



The pronotum is more extensively pigmented than in H. parenthesis 

 or apicalis. In one specimen the mesocaudal light spot is wholly absent. 

 In the other cases it is small and triangular, with the point caudal. The 

 spots 4, 5, and 6 are confluent, sometimes leaving an inclosed light spot, 

 sometimes with the pigment continuous. The entire suture is pigmented 

 and confluent with the spots just mentioned. The pigment extends laterad 

 in the basal region to spots 1 and 3. The pigment generally involves the 

 base of the elytron, but in one case is free from it. 



Var. A. The spot 3 free. 



Var. B. The spots 1 and 3 free. 



While the amount of confluence at the base of elytron is thus seen to be 

 variable, the distinctive feature of the species, the pigmented suture, is 

 constant. The species is named in honor of Mr. C. W. Leng, student of 

 this genus. 



3052. Hippodamia falcigera Crotch. 



Distribution: Hudson Bay, Great Slave Lake. 



The specimens in the Horn and Leconte collections, in addition to their 

 lack of discal spots and to the more elongate elytra, have a lateral margin 

 which is straight or even slightly concave for a short distance. The vittse 

 are much less sinuate in the apical region than those of H. sinuata (see 

 fig. 7) . A large series will throw light upon its relationships. For the 

 present we must conclude that it has probably developed along an inde- 

 pendent line rather than from H. sinuata.
