Westwood has observed 3hjopa atra fly-ing about sand-banks in which were the burrows of various bees,mid by other authors the genus is said to be parasitic on bees. The genus Pipuncuhis represents a small group in whichthe head is almost entirely occupied by the eyes, the front andface being exceedingly narrow, while the antennae have a basalbristle. Loew considers the genus Scenojnnus as the type of a dis-tinct family, hinting at its relationship with the genus is known by the short antennae, without style or bris-tle ; and by the short proboscis with its broad fleshy end. Thelarvae are long, very slender, much like those of Thereva, andthe pupa is much like that of Leptis. Mr. Sanborn has Say (Fig. 322 ; a, larva). The larva is found under26. 402 DIPTERA. carpets, and is remarkable for the double segmented appearanceof all the abdominal segments, except the last one, so that thebody, exclusive of the head, seems as if twenty-jointed insteadof having but twelve joints. The head is conical, one-thirdlonger than broad, and of a reddish brown color, \yhile thebody is white. It is .65 of an inch in length. The larva isalso said to live in rotten wood, and is too scarce to be destruc-tive to carpets. The fly is black, with a metallic hue, andwith pale feet. The genus Platypeza also represents the Platyjiezidce ofMeigen, the antennae of which have an apical bristle, with themale genital armor (hypopygium) turned symmetrically underthe abdomen. The middle tibiae are provided with spurs, andthe empodium is wanting. The larva is flat, with rigid curvedbristles along the side. It lives i
