Vedalia cardinalisand Novius koebelei have com-pletely subjugated the cot-tony-cushion scale. Orcuschalybeus is effective againstthe yellow scale. Rhizobius ventralis is a very useful destroyer of theblack scale. Scymnus vagans is an enemy of the red spider. Rhizobiuslopantha makes some headway against the purple scale, and Cryptolsemusmontrouzieri cleans up the mealy-bugs in greenhouses. The otherspecies are general feeders. If it were not for these industrious enemies of our fruit and vinepests, California would be far from ranking to-day the chief fruit-producing State of the FIG. 100. Novius koebelei. Section HETEROMERA. This section is a rather miscellaneous lot of beetles, including severalsmall obscure families, as well as two large ones. All those beetleswhich have the front and middle feet with five tarsal segments andthe hind feet with four are included in it. The family Tenebr-ionidse are the darkling beetles. They are usu-ally dark brown or black in color, oblong or oval in shape, have thehead more or less inserted in the prothorax, and, on account of theirlong legs, are very awkward in their movements. Both adults andlarvae are scavengers, the latter much resembling wireworms in appear-ance. The common pinch-bug, Eleodes sp., which when disturbedstands on its head and emits an ill-smelling fluid, is a familiar meal-worm beetle (Tenebrio molitor), bred by bird fanciers forfood, and Tenebrio obscwus, found about stored g
