In the Munich Catalogue (1870) 583 genera and 4222 speciesof are enumerated, and Mr. Champion in hisSupplementary list (Mem. Soc. Ent. Belg. iii, 1895) enumerates430 more genera and 5063 more species, so that the presentnumber known must be well over 10,000. So far as the Indianfauna is concerned very little interest has been taken in the. 6 Fig. 68.— Toxicum quaclricome, male, and head and thorax of female, family^ about 40 genera are represented in the Catalogue ofGemminger and von Harold, and between 30 and 40 in theSupplement, but the number of species is proportionally verysmall and does not amount to more than about 300; in fact, inthe Supplement only some 70 or 80 species out of the 5000are recorded as from India and Ceylon. Allusion has already been made to the larvae, which aretough and cylindrical, and resemble the wire-worms of theElatekid^e, the chief differences consisting in the non-connateclypeus, the large and plainly visible labruin, and the less complexterminal segment of the abdomen. The pupae appear to be broadin proportion to the larvae and to be furnished with extensions at 160 INTRODUCTION. the sides o£ the abdominal segments, and with longer or shorterrobust cerci. Several of the larvae and pupae have been beauti-fully figured
