Lyda ratzeburgi (Dalilb. Ratzeburg Forstins. iii, 80) is a new species 

 of Northern Germany and Sweden. 



Forster (Eutom. Zeit. 202, 287) has described as new a number of 

 species collected about Aix la Chapelle, of which, ] . Monophaduus inquilinus, 

 reared from many-chambered spongy galls on oak twigs, does not differ in 

 the description from Tenthr. (All.) melanocep/iala. 2. Dineura dorsalis is 

 a slight variety of T. (All.) opaca, F., (verna, Kl.) 4. Perineum ducalis, the 

 male of T. (All.) nitida, Kl. 5, 6. Allantus dedpiens and omissus, varieties 

 of T. niarginella, F., which is very inconstant, not only in the markings of 

 the body, but also in the colour of the wings. Only the third species, Cephas 

 flavimntris, which I do not know, appears to be new. 



Gimmerthal (Eutom. Zeit. 30) has published descriptions of some new 

 Tenthrediuidse which were collected, in the neighbourhood of Riga, upon 

 young pine trees. The three species of Nematus,Jlavus, schmidtii, klugii, are, 

 in Hartig's opinion, new, though not described particularly enough to be 

 identified with certainty. 4. Dineura liartig'd is a variety of T. (All.) 

 degeeri, KL, and 5. Eriocampa livoniensis, as it would appear, T. (All.) 

 (ethiops, F. 



Curtis (Trans. Linn. Soc. xix, 249, pi. 31) has described the singular 

 chrysalid web of a Brazilian insect allied to Hylotoma, for which he makes 

 a new genus, Dielocenis, corresponding to the fifth sub-section of Hylotoma 

 in King's arrangement, (Jahrbuch. 248). With Schizocerus it agrees in 

 the third joint of the feelers in the male being cloven, but the parts 

 of the mouth differ, the upper lip being nearly circular, and the inner 

 blade of the jaws not narrower than the outer one. D. ellisii, Curt., $ ' 

 Blackish blue, the base joints of the feelers, the face, the collar, and the legs, 

 red, the hind feet black, the wings limpid. The female agrees with the same 

 sex of Hyl. formosa, KL, in most respects, except that, as the author remarks, 

 the second feeler-joint is brown above, the belly not red at the base, and 

 the hind shanks not entirely black, but yellow at the root and inside, the 

 hind feet in both species are brown, with the base whitish. The larva is 

 IG-footed, hoary green, with cross rows of black warts, the head rufous, 

 with a black spot round each of the eyes. When preparing for their trans- 

 formation, the larvae unite in spinning upon a branch a nest of an elongated 

 oval shape, 4-5 inches in length, or it may be larger or smaller. Within 

 this each of the larvae has its separate solid cell so arranged that the longer 

 axis is at right angles with that of the twig, and the cells are set almost 

 as close to one another as in a honeycomb. The individual cells are laid over 

 each other in three or four layers, so that the undermost lies immediately 

 against the twig, and that every one of them is detached at both ends. The 

 whole is then surrounded with a common case, which consists of a coarse 

 open silk inside, and outside of a close web, washed over, as it were, with
