261 THE ENTOMOLOGIST. 



Eridania, Cram., is fixed as the type of Xylomyges, Guen., a 

 genus with only four species, all of which are South American. 



The type of Petilavqxi,, Auriv., is minima, Haw., = arcz/osa. Haw., 

 and Acosmetia morrisii, Morris, Naturl. ii. p. 88 (1837); Humphrey 

 and Westwood, Brit. Moths, i. p. 245, pi. 54, fig. 12, is quoted in the 

 synonymy. 



The 89 species under Monocles, Guen. (t. nucicolor, Guen.), are 

 divided up, on antennal characters, into four sections, but as regards 

 the first two and the last, only one species is assigned to each. All 

 the others are included in Sect, iii., and are largely South American 

 species ; venustula, Hiibn., alone is European. 



" Agriopis " viridis, Leech, is the type of Daseochceta, Warren 

 (1907), and '' Diphtera" pa/Z/fZa, Moore, the type of Diphtherocome, 

 Warren (1907). The latter is merged in the former, and the two 

 species mentioned with twelve others, including alpium, Osbeck,= 

 orion, Esp., referred by authors to Diphthera, Hiibn., are here in- 

 cluded in one or other of the five sections of Daseochceta. 



Gemella, Leech, originally described under Perigea, Guen., is the 

 type of DysmiUchia, Speiser (1902) ; Phalacra, Stand. (1892), and 

 MilicJiia, Sneller (1898), are both preoccupied names. 



The 448 excellent figures in the Atlas, drawn by Horace Knight, 

 are capitally reproduced in chromo by West, Newman & Co. 



1. Appendages of the Second Abdominal Segment of Male Dragon- 



flies [Order Odonata). By Oliver S. Thompson (New York 

 State Museum, Bulletin 124, pp. 249-263). Albany. 1908. 

 This is a most useful paper on the unique structural arrange- 

 ments for copulation in the Odonata. Forms of the appendages in 

 the different divisions of the order are fully illustrated, but in some 

 cases fuller references to the figures seem to be called for. 



2. Les Bhaphidides {Lis. Nevr.) dii Musde de Paris. By Longings 

 Navas (Annales de la Society Scient. de Bruxelles, 28 Jan. 1909). 



3. Neuropteros y Ortdpteros mievos de Aragon. By Longings Navas 



(Boletin de la Soc. Arag. de Cien. Nat. May, 1909). 

 Perla kheili, amongst the Neuroptera, and Omocestus rufipes var. 

 rufitarsis, Stauroderus intricatus, and Pamphagus nugatorius amongst 

 the Orthoptera, are here described. 



4. Monografia de la Familia de los Dildridos {his. Neur.). By 



Longings Navas (Mem. de la Real Acad, de Cien. y Artes de 

 Barcelona, June, 1909). 

 An important paper of fifty-five pages, with two plates, devoted to 

 this strange and not too well known group of the Neuroptera 

 (restricted sense). They are a small group of insects near the 

 Hemerobii, chiefly found in the Old World. The male possesses 

 pectinated antennae, and the female has a long ovipositor.
