. A manual for the study of insects. Insects. COLEOPTERA. 589 is of a uniform black color (Fig, 718). Epicauta drierea (E. ci-ne're-a) is sometimes clothed throughout with an ash-colored pubescence, and sometimes the wing-covers are black, except a narrow gray margin ; the two varieties were formerly consid- ered distinct species: the first is commonly known as the ash-colored Blister-beetle, the last as the { Margined Blister-beetle. Another common Fig. 718. cies is the Striped Blister-beetle, Epicauta vittata (E. vit-ta^- ta); this species is yellowish or reddish above, with the head and prothorax marked with black, and with two black stripes on each wing-cover. , In the far West very many species of blister-beetles occur—so many, in fact, that we cannot undertake to specify them here. The family RHIPIPHORIDiE (Rhip-i-phor^i-dae) includes a small number of beetles, which are very remarkable in structure and habits. The wing-covers are usually shorter than the abdomen, and narrowed behind (Fig. 719); sometimes they are very small, and in one exotic genus they are wanting in the female, which lacks the wings also, and resembles a larva in form. The antennae are Fig. 719. pectinate or flabellate in the males, and frequently serrate in the females. The adult insects are found on flowers. The larvae that are known are parasites, some in the nests of wasps, and some on cockroaches. The family Stylopid^ (Sty-lop'i-dse) includes a small number of minute insects which differ so much from ordi- nary beetles that they have been classed by some writers as a distinct order, the Strepsiptera (Strep-sip'te-ra). In the males the elytra are reduced to slender, leathery, club-shaped appendages; while the wings are very large, fan-shaped, and furnished with a few diverging veins. The females have neither wings nor elytra, and resemble a larva in form. They are always contained in the pupa case in the body of a wasp or bee, which they infest parasitically. The point. Please n
