ing Echo margarita. Dorothea rather suggests the males of 

 the species of Calopteryx of the cequabilis group, especially 

 dimidiata, which species also were suggested to de Selys by 

 Vestalis apicalis. 



A New Species of Ecitopora. 



By Charles T. Brues. 



This is the third species of Ecitopora to be discovered in the 

 United States living, like the other species of the genus, in the 

 nests of the blind legionary ants, Eciton. The species c'kn be 

 readily distinguished by the accompanying figures. 



Ecitopora nitidiventris sp, nov. 

 Length 2.25 mm. Pale fuscous. Head fuscous, with rather distinct 

 sparse punctures. Thorax testaceous. Elytra testaceous, but appearing 



almost piceous in certain lights. Ab- 

 domen fuscous, lighter at apex and 

 also at base, especially below. Legs 

 pale testaceous. Antennae thickened 

 toward the tips ; fuscous, paler at base ; 

 joints after the first, of about equal 

 length, except the last, which is coni- 

 cal and a little longer than the two 

 preceding joints ; each of the latter 

 one and three fourths times as wide as 

 long. Thorax slightly wider than long, 

 narrowed slightly and broadly rounded 

 behind ; its lateral depressions deep 

 and extending for its entire length ; 

 posteriorly there is a shallower median 

 depression. Thorax and elytra sparsely golden pubescent. Abdomen 

 bare, shining ; each segment with a marginal row of about eight long 

 hairs. Abdomen of equal width, rather suddenly obtusely acuminate 

 at tip. 



Described from two specimens collected in a nest of Eciton 

 coecum Latr., at Austin, Texas, during March, 1902. 



E. nitidiventris is readily distinguished from E. laticollis 

 Brues by the form of the thorax, and from E. tenella Wasm, 

 by the bare, nonpubescent, shining abdomen, which has fewer 

 marginal hairs upon the dorsal segments.
