Alabama and New York, rare. For a variety from the Hentz collection, with- 

 out thoracic spots, I am indebted to S. S. Haldeman. This species establishes a 

 passage to the next division of the genus. The maxilhB are only half as long as 

 the body, as in the preceding species, and the head is shorter than usual, as in 

 N. p a 1 1 i a t a ; the 2d joint of the antennae is half as long as the 3d.

 antennae with the 2d joist very small; maxillae about half the length of the 

 body. Thorax yellow, one half wider than long, sides parallel, anteriorly

Two specimens^ Sta. Fe. Mr. Fendler. The maxillae in this species are only 

 one fourth as long as the body; the second joint of the antennae is more than 

 half as long as the th:rd; the first is indistinctly testaceous. The spurs of the 

 posterior tibiae are small and acute.

One specimen, Georgia. Body testaceous, with a few yellow hairs. Head 

 densely punctured, trian^jular, mouth elongated, palpi and maxillae blackish, the
