I do not find the differences in the hind angles and the scutellar stria constant, i. e. they are not al- ways concurrent. I am also willing to go a step further and add rugicoUis to the synonymy. N'. y.—The Mud-wasp you send, reared from a series of cells agglomerated round a twig, is Odynerus birenimaculatus Sauss., a species allied to O. flavipes Fabr., which we represent in Fig. 59. The parasite bred therefrom is Cryptus jtinceus Cress, {vide Fig. 60). This parasite infests also other Mud-wasps, e. g. those belonging to the genus Agenia. Your wasp uses small Lepidopterous larvce, such as those belonging to the leaf-rollers {TortiicidiE) wherewith to store its nest, first paralyzing them as is usual with the insects of its family. In the case of the specimen from which our illustration was made the wasp built in the hole of an old cotton-spool, making two cells and closing up. Crvptus junceus, twice nat. size (after Riley). each end of the hole in the spool with clay. Other species of the genus Odynerus build either in wood that has been bored by other larvje, or in the interstices of walls, while one species (conformis Sauss.) which we find commonly around Wash- ington makes use of the burrows of a mason-bee (Afe/issodfs taiirca Say). Monographs again.—Will you please inform me through the columns of the American Ento- mologist, whether there are Monographs of the Elateridce, Curciilionidii, and CoccidcE by which species can be determined ? , to whom shall I address mj'self to ob- tain the government publications on the subject of entomolog}'? I am so unfortunate as to have no friends in congress to assist ine in obtaining them.—C. D.
