Mulsant's description seems to apply to the same beetles later named H. trivittata by Major Casey, and his type came from the same locality. This Californian species (see fig. 35), with the vittse complete, is, however, distinct from the other beetles often called H. sinuata, which have the vittae very strongly bowed in the apical half of the elytra, or incomplete or lacking; these latter are properly placed in H. spuria. Mr. Nunenmacher informs me that H. sinuata is restricted to the salt- marshes, and in my collection in California I failed to find them outside of the marshes. It is this fact, together with the lack of intergrades, that causes me to consider them specifically distinct. This isolation by its decrease of interbreeding would have afforded the opportunity to establish intersterility. Var. crotchi. The suture black for only one-third of the length. One specimen from San Fran- cisco in the collection of Mr. Leng. 3050. Hippodamia tredecimpunctata Linnaeus. Distribution: Europe, United States, and Canada. This species is the least variable of all the widely ranging species of Hippodamia. Yet large series show variation (see figs. 36 to 38). This is parallel in part to that given for Europe by Weise (1899) and Mulsant (1846). The names and letters employed by them will be used. While.
