An enumeration of the Diptera thus far collected in Sicily, M. Bezzi and T. 

 de Stefani-Perez (Xaturalista SicUiano, n. ser., 2 (1S97), No. IS, pp. 25-72). — After 

 an introduction in which, among other things, some historical data are brought out 

 showing the increase in the knowledge of the group, a copious bibliography is given. 

 Then follows a classified list of the species of Diptera found on the island. The 

 forms peculiar to Sicily are indicated.

 butterflies and moths" deals with the first portion of the Geometrae. 



New Hymenoptera frcm New Mexico, T. 1). A. Cockerell (Entomologist, 30 

 (1897), No. 408, pp. 135-138). — The following new species and varieties are described: 

 Cerceris acanlhophihis, Encerceria vittatiferona var. tricolor, Spilomena foxii, 1'hotopsis

 Gossip, n. ser., 3 (1897), No. 35, p. 302). — The author studied specimens taken from a

 (1897), pp. 194-197, abs. in Jour. Boy. Micros. Soc. London, 1S97, No. 3, p. 201).— Some 

 of the structural peculiarities of this dipterous larva' are described. The gut is sim- 

 plified by parasitism. The gastric appendages are suppressed and the proventric- 

 ulus is replaced by a hard muscular cushion on the upper wall of the esophagus. 

 A peculiar organ is formed on each side of a somite by a group of giant cells. Its 

 function is thought to be excretory.

 effective it does not act as quickly and in showery weather is not preferable to Paris 

 green. Experiments with an atomizer for applying the Bug Death and furnished 

 by the same company resulted very unfavorably to it. It requires 28 minutes to do 

 the work that might be done with Leggett's gun in 8 minutes.
