284 E. BRENDEL, M. D. 



There are two specimens before me said to be E. scitula from Penn- 

 sylvania and colon from Iowa, which do not agree with the above 

 descriptions. Euthlndes lata n. sp. (PI. IV, fig. 15) the supposed 

 colo7i, is coarsely, faintly and sparsely punctured at the sides of the 

 elytra, otherwise impunctate; the vertex without impressions; the 

 pronotum with median basal punctures, a longitudinally elongate 

 fovea next to the posterior angle and between it and the medial one 

 two confluent punctures; elytra one and one-half times longer than 

 wide. 



The supposed E. scitula {Enthiodes cridaia n. sp.) (PI. IV, fig. 16) 

 is extremely fine and sparsely punctulate and 0.66 mm. long; the 

 head is carinate in the middle, on either side of the carina impressed ; 

 the pronotum has an abbreviated basal line, a transverse, conspicu- 

 ous fovea one-fifth of the length of the disc from the base, on either 

 side in the middle between the medial and the anteriorly prolonged 

 lateral fovea is a deep puncture ; the basal cornei's are explanate. 

 Length 1.2 mm. Pennsylvania (Jerome Schmitt, H. Ulke).
