NATIONAL MUSEUM BULLETIN 209 penultimate segment about as long as wide; mesopleuron mat, with fine close punctures, its pubescence of moderate length, whitish; long erect setae on mesopleuron unusually numerous. Black. Head and thorax with a strong greenish blue iridescence; legs and abdomen with a weak or faint dark bluish iridescence; stripe on lateral ± of face, extending to lower part of frons, whitish; tegula, palpi, and sometimes front femur and tibia sometimes brownish; wings faintly infuscate. Female: Forewing to mm. long; clothing hair of frons short, rather dark, arising from subadjacent punctures on a mat background; apical margin of clypeus broadly angled to a rounded median point; second flagellar segment about as long as wide; groove of pronotum without distinct cross wrmkles; venation as noted in the key; pygidial area polished, without evident punctures. Black, with a bright greenish blue iridescence, strong on the head and thorax, weaker on the legs and abdomen. Wings hyaline to weakly infuscate, according to the subspecies. This is one of three Nearctic species of Auplopus with black legs and body and a strong iridescence, the other two being caerulescens and nigrellus. The three are easily separated in the male, but with difficulty in the female (see the comparisons in the keys). There are two subspecies of architectus—metallicus of the Pacific States and British Columbia and architectus mostly east of the Rocky Mountains. 9a. Auplopus architectus metallicus (Banks) Pseudagenia metallica Banks, 1910, Journ. New York Ent. Soc, vol. 18, p. 125, $. Type: ?, Claremont, Calif. (Cambridge). This subspecies differs in averaging a little smaller, with darker iridescence, fewer long erect hairs, and the wings somewhat more.
