244 NORTH AMERICAN TRYPETINA. 



crossbands, converging towards the posterior margin, an incomplete 

 band beginning at the anterior margin and running as far as the third 

 longitudinal vein, and a border of the costa, beginning at the second 

 crossband and ending at the tip of the second posterior cell ; the whole 

 of this picture being brown. Long. corp. 0.29 ; long. al. 0.29.

I have nothing to add to the description, given in the first part 

 of these Monographs, but I must observe that, deceived by Mac- 

 quart's insufficient description of his T flavonotata, I have taken 

 it to be merely a paler variety of T. electa Say, while a specimen 

 received since then has convinced me that it is a very closely 

 allied but distinct species.

Observation. — Trypeta electa belongs in the genus Spilo- 

 grapha. 



13. T. flavonotata Macq. % . — Lutea, vittis thoracis et scutello 

 unicolore pailidioribus, tibiae posticae setulis brevissimis pallidis subci- 

 liatae ; alse hyalinse, fasciis duabus postice paulo abbreviatis adversus 

 marginem posticum convergentibus, strigula interjecta a costa prope ad 

 venam longitudinalem tertiam ducta et costae ipsius limbo inde a fascia 

 secunda usque ad cellulae posterioris secundae apicem pertinente, fuscis. 



Clay-yellow, longitudinal stripes of the thoracic dorsum and the uni- 

 colorous scutellum paler; hind tibiae somewhat ciliated with very short, 

 pale bristles ; wings hyaline, with two crossbands, which are somewhat 

 convergent posteriorly and interrupted a little before the posterior mar- 

 gin, a little crossband between them, extending from the anterior mar- 

 gin almost to the third longitudinal vein, and a border of the costa, 

 running from the second crossband to the tip of the second posterior 

 cell; the whole picture being brown. Long. corp. 0.18; long. al. 0.21 

 —0.22.

This species is very like Trypeta electa Say, differs, however, 

 from it as follows. It is smaller ; the head is comparatively 

 smaller and has much narrower cheeks. The third antennal 

 joint ends at a much sharper angle. In what way the picture 

 of the thorax differs from that of T. electa cannot be well 

 ascertained in my specimen, in which it has become somewhat 

 indistinct, probably in the process of drying; the whitish stripe, 

 running from the humerus to the root of the wings, is very per-
