it differs so much from our local species, which is generally supposed 

 to be the morio of Fubricius, that I cannot consider them as identical, 

 and have therefore described it under another name. The specimens 

 before 1113 of our local species differs from the above species by being 

 smaller (12 J lines long, 18 lines expanse of wings), the wings have a 

 bronze reflection, the metathorax is strongly rugose, or rather coarsely 

 reticulated, the abdomen in the 9 1S broader and much more com- 

 pressed towards the apex, and the punctures of the body are more 

 distinct; but none of the specimens before me have the anterior legs 

 testaceous, or the front of the head with yellow spots, as stated by Fa- 

 bricius and Olivier. I3rulle, however, makes no mention, in his descrip- 

 tion of morio Fabr.. of the front legs being testaceous, or the head 

 having yellow spots. Although this species and morio are closely allied, 

 yet the former may be easily distinguished by the larger size, the deep 

 violaceous wings, and the sculpture of the metathorax, which is not at 

 all strongly rugose and reticulated, as is the case with morio, but is ra- 

 ther finely striated on the sides and posterior face. 



Thyreodon fulvescens, n sp. 



Fulvous or honey-yellow; face and orbits yellow ; wings yellow : basal half 

 of 2nd abdominal segment above, black. 



Male. — Fulvous or honey -yellow, shining, clothed with a short yel- 

 lowish pubescence, more obvious when viewed laterally ; face, orbits, 

 clypeus. mandibles, except tips which are black, yellow; palpi fulvous; 

 antennae two-thirds the length of the body, fulvous, the basal joint be- 

 neath, yellow. Thorax : mesothorax very finely and indistinctly punc- 

 tured, the dorsal furrows deep and converging on the scutellum; pleura 

 smooth and polished; scutellum convex, polished, tinged with yellow- 

 ish ; metathorax opaque, rather abruptly sloped behind, indistinctly 

 sculptured above, but rather coarsely reticulated on the sides ; tegulse 

 yellowish. Wings yellowish-hyaline, the apical margins fuliginous; 

 nervures ferruginous. Legs color of the body, the tibiae and tarsi 

 somewhat paler. Abdomen elongate, rather broad and compressed to- 

 wards the apex, smooth and polished; basal half of the second segment 

 above, black; anal processes rather thick and obtusely pointed. Length 

 123 lines; expanse of wings 17 lines. 



Collection. — Ent. Soc. Philad. One specimen. 



Thyreodon affinis. n. sp. 



Fulvous or honey-yellow; tip of antennae and base of 2nd abdominal segment 

 blackish; wings fuscous with a violaceous reflection. 



Male. — Fulvous or honey-yellow, shining, clothed with a very short. 

 yellowish pubescence, more obvious when viewed laterally; orbits paler.
