GRASSHOPPERS-GURNEY AND BROOKS 5The male genital mass or assemblage, preferably known as the phallic complex, including the aedeagus and its supporting apodemes, as well as the epiphallus-located anterior to the aedeagus ( fig. 2,6) is situated at the end of the abdomen beneath the supra-anal plate and the pallium (membranous covering usually dorsad of the subgenital plate). Taxonomically, the aedeagus and epiphallus are the most important organs of the phallic complex, and the critical parts of each are illustrated by M. femur-rubrum ( fig. l,h,i
Illustrated keys and descriptions of 26 genera and 137 species or subspecies of Elateridae of southern Alberta, Saskatchewan and Manitoba are presented. The distribution of each species is described in relation to the bio-ecological regions in the three Provinces. No new species are described.
For many years studies of cutworm bionomics and control, especially of pest species, have been carried on in the Prairie Provinces of Canada. During these studies a number of cutworm parasites and hyperparasites of the bombyliid generaPoecilanthraxOsten Sacken,VillaLioy, andHemipentherLoew have been encountered. These species do not appear to be important factors in the natural control of cutworms, for they cause from two to five per cent of the total parasitism. No detailed data are available on the life-history of any of the species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
