264 THE ENTOMOLOGIST. 
Hridania, Cram., is fixed as the type of Xylomyges, Guen., a 
genus with only four species, all of which are South American. 
The type of Petzlampa, Auriv., is minima, Haw.,= arcuosa, Haw., 
and Acosmetia morrisit, Morris, Naturl. ii. p. 88 (1837); Humphrey 
and Westwood, Brit. Moths, i. p. 245, pl. 54, fig. 12, is quoted in the 
synonymy. 
The 89 species under Monodes, 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, Htibn., alone is European. 
‘““ Agriopis”’ viridis, Leech, is the type of Daseocheta, Warren 
(1907), and “ Diphtera” pallida, Moore, the type of Diphtherocome, 
Warren (1907). The latter is merged in the former, and the two 
species mentioned with twelve others, including alpiwm, Osbeck, = 
orion, Kisp., referred by authors to Diphthera, Hiibn., are here in- 
cluded in one or other of the five sections of Daseocheta. 
Gemella, Leech, originally described under Perigea, Guen., is the 
type of Dysmilichia, Speiser (1902); Phalacra, Staud. (1892), and 
Milichia, 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 Outver 8. THompson (New York 
State Museum, Bulletin 124, pp. 249-263). Albany. 1908. 
TuIs 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 Rhaphidides (Ins. Névr.) du Musée de Paris. By Lonainos 
Navas (Annales de la Société Scient. de Bruxelles, 28 Jan. 1909). 
3. Neurdpteros y Ortépteros nuevos de Aragén. By Loneinos Navas 
(Boletin de la Soc. Arag. de Cién. Nat. May, 1909). 
Perla kheili, amongst the Neuroptera, and Omocestus rufipes vay. 
rufitarsis, Stauroderus intricatus, and Pamphagus nugatorius amongst 
the Orthoptera, are here described. 
4, Monografia de la Familia de los Dildridos (Ins. Neur.). By 
Lonainos Navas (Mem. de ‘x 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 antennz, and the female has a long ovipositor.
