Hab. United States, New England States 4 , Maryland \ Pennsylvania 1 3 7 , Cali- 

 fornia 4 , Washington*, Kansas 4 , Arizona \— Mexico 8 , Venta de Zopilote 2800 feet, 

 Chilpancingo 4600 feet, both in Guerrero (H. H Smith). 



Seven specimens. In size, and colour of the abdomen, these Guerrero examples 

 vary not a little. Some of them agree well, however, with others from Kern Co., 

 California, and Connecticut, in my collection. 



4. Zodion auricaudatum, sp . n^? ( (Tab. II. figg. u, $ ; Ua, profiie.) 



Front, on tho upper two-fifths, opaque black ; on the lower parfc, opaque yeUow or reddish-yellow. Antennaj 

 reddish-brown or brownish-red, on the underside yellow j third joint a little more than half the length 

 of the second. Faee lighter yellow than the front; cheeks dark brown. Thorax opaque black; dorsum 

 with two slender whitish lines, separating three deep black, velvety, opaque stripes— the middle one 

 slender, the lateral ones oval. Abdomen opaque black, the anterior segments with a whitish pruinosity ; 

 third segment with the posterior margin, and two oblique spots, contiguous with the posterior band 

 posteriorly, and forming an interrupted band, opaque golden-yeUow ; fourth and fifth segments each 

 golden-yeUow, with or without an interrupted black band ; sixth segment wholly opaque yellow. Lega 

 black ; base of all the tibiae, and all the tarsi, save the distal joints, yeUowish. Wings almost uniformly 

 smoky. 



Length 7-8 mUlim. 



Hab. Mexico, Chilpancingo and Tepetlapa, both in Guerrero (H H Smith). 



Three specimens. The one from Tepetlapa differs from the others in having the 

 yellow of the abdomen of a lighter colour, the third segment with a spot only on each 

 side, and the fourth and following segments wholly yellow, save two small black spots 

 on the fourth segment. The abdomen evidently varies in the extent of the yellow 

 opaque markings. 



5. Zodion splendens.

Hab. United States, Kansas 2 , Montana 2 , Arizona 2 . — Mexico l . 



Although I have not seen a specimen of this species from Central America, I believe 

 that the above synonymy will be found to be correct. 



6. Zodion zebrinum.
