An or- der of meta bolo us hexapod insects. They are two- insects, or flies, with two membranous wings with radiating nervures, not folded at rest, a posterior pair be- ing only represented by halteres or poisers; no mandibles as such, but a suctorial proboscis instead, formed of modi- fied mandibles, maxillæ, and the central labium, here called glo arium; usually two maxillary but no labial palpi; antennæ generally short; two large compound eyes, often of you sands of facets, and three ocelli or simple eyes; and the prothorax and metathorax reduced, the mesotho- rax being correspondingly developed. Metamorphosis is complete; the larvæ are apodal, or with only rudimentary feet; the pupæ are usually coarctate (see cut under coarc- tate ), sometimes obtected. The common house-fly, blue- bottle, etc., are characteristic examples. The power which many of these insects have of walking on smooth surfaces with back downward is due to the construction of the feet, which act as suckers. They have, besides the ordinary two claws, several little cushions called pulvilli, beset with fine hairs expanded at their tips into a kind of disk; the adhe- sion is aided in some cases es by a viscid secretion of these hairs. The order is a very large one: there are said to be 9,000 European species alone, supposed to be not a twenti- eth part of the whole number. About 4,000 are described as Dipterini (dip-te-ri'ni), n . pl . [NL., Dipterus + -ini .] A group of fishes: same as Dipterida . L. Aga iz , 1843. dipterist (dip'te-rist), n.

They are characterized by two wings upon the summit of the fruit (formed by an enlargement of two calyx-lobes), and by their resinous balsamic products. The order includes the gurjun-balsam trees (species of Dipte- rocarpus ), the Sumatra camphor-tree ( Dryobalanops aro- matica ), the white dammar-tree ( Vateria Indica ), and the sal or saul-tree ( Shorea robusta ), which next to teak is the most valuable timber-tree of India.
