I do not find the diflerences 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 rugicolUs to the synonymy. N. J.—The Mud-wasp you send, reared from a series of cells agglomerated round a twig, is Odynerus tiirenimaculatus Sauss., a species allied to O. flavipes Fabr., which we represent in Fig. 5g. The parasite bred therefrom is Crvptus junceus Cress, {vide Fig. 60). This parasite infests also other Mud-wasps, e. g. those belonging to the genus Agenia. Your wasp uses small Lepidopterous larvae, such as those belonging to the leaf-rollers {Tortricida:) wherewith to store its nest, first paralyzing them as is usual wjth 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 LFig. 60.]. Crvptus junceits, 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 larva:, or in the interstices of walls, while one species {eonforinis Sauss.) which we find commonly around Wash- ington makes use of the burrows of a mason-bee {Afe/issodes taurea Say). Monographs again.—Will you please inform me through the coUimns of the AMERICAN Ento- MOLCJGIST, whether there are Monographs of the Elaleridic, Curculionidic, and Coccidir by which species can be determined ? Also, to whorii shall I address myself to ob- tain the government publications on the subject of entomology? I am so unfortunate as to have no friends in congress to assist me in obtaining them
