prolonged to the middle or beyond, the humeral, postmedian and sub- 

 apical spots small and generally separate, although the postmedian 

 pair are not infrequently united. This subspecies has not been 

 named apparently and may be called Hippodamia sinuata disjuncta 

 n. subsp., described from thirty-one type and paratype specimens from 

 Salt Lake City and IVJurray, Utah. Casey described it under the 

 name of spuria and his americana (not Crotch) seems hardly more 

 than an individual variation. The type of disjuncta will be placed in 

 the U. S. National Museum. 



5. Hippodamia 15-maculata Mulsant. 



Hippodamia 15-maculata Mulsant, Species des Coleopteres trimeres securi- 

 palpes, p. 20, 1851. 



This species which is often confused with convcrgcns has the 

 genitalia very distinct from any other species. Two males have 

 been examined, one from Badger, Nebraska (W. C. Colt), and the 

 other from Batchawaung Bay, Lake Superior, Ontario (Hubbard and 

 Schwarz). 



6. Hippodamia cockerelli Johnson. 



Hippodamia cockerelli Johnson, Carnegie Inst. Washington, Publ. 122, p. 49, 

 fig- 33, 1910. 



The type of this species in the U. S. National Museum has been 

 studied and it has been the only specimen examined. 



Orcgoucnsis Crotch and dispar, lilliputana and puncticoilis of 

 Casey have not been studied. They all seem to be closely related, 

 and some of them if not all are likely to prove to be forms of one 

 species to which cockerelli may also belong. 



7. Hippodamia lecontei Mulsant. 



Hippodamia lecontei Mulsant, Species des Coleopteres trimeres securipalpes, 

 p. 1010, 1851. 



This species seems to be distributed throughout the Rocky Moun- 

 tain region, but does not appear to be readily divisible into geographic 

 races. Specimens with the basal bar broken up into a scutellar and 

 the humeral spots occur in most localities apparently in about equal 

 numbers with the form having the basal bar complete. Mulsauti 

 Leconte, abducens Casey and bozvditchi Johnson are probably forms 

 of this species. It is frequently mistaken for H. 5-signata (Kirby).
