New genera are marked (*) ; the figure 

 following the name of the genus indicates 

 the number of the plate. 



The total number of species enumerated 

 is 1,101 contained in 157 genera; more than 

 100 of the species are unnamed owing to the 

 insufficiency of the material. Seventy-three 

 of tlie species found in the Central American 

 fauna occur also in America north of 

 Mexico.

TWO FORMS OF PRODOXUS COLO- 

 RADENSIS RILEY. 



The two forms here described were taken 

 by Mr. R. R. Larkin on flowers of Yucca, in 

 company with the type form, in April, near 

 the N. M. Agricultural College, Mesilla 

 Valley, New Mexico. Their description as 

 varieties will probably prevent them from 

 being regarded as distinct species by those 

 who may receive specimens without knowl- 

 edge of the circumstances under which they 

 occurred. 



(i.) Prodoxus coloradensis var. n. hiiittis. 

 Differs from the type in being white, with 

 only indistinct traces of the black markings 

 on the primaries. Of these markings, the 

 marginal-band and the Y-mark are usually 

 most distinctly traceable. The insect appears 

 at first sight either white, or white slightly 

 clouded with grey, but on comparison with 

 the typical form it is seen that the markings, 

 so far as traceable, exactly correspond in 

 position. 



(2 ) Prodoxus coloradensis var. n. ronfluens. 

 The two innermost dark bands or primaries 



coalesced in such a manner as to form a J^, 



so that the dark markings of the wing consist 

 of the marginal band, and two Ys, one in- 

 versed, the other, as in the type, in the 

 ordinary position.

WEED'S LIFE HISTORIES. 



Books about insects for the ordinary reader 

 are not common in America, and when one 

 appears which is simple, straightforward and 

 correct, and especially if it deals with the 

 creatures in all their stages, we are glad to 

 welcome it. Such is Weed's Life Histories of 

 American Insects, just published b^' Macmil- 

 lan for $1.50. The sketches are mostly short 

 and unrelated, so that the book may be taken 

 up at any point without missing connections, 

 but it is suggestive of a vast deal more to 

 learn and it is generally accurate and well 

 presented. We notice only one bad slip, 

 where a Locustarian is figured as a "leaf- 

 insect" — which it certainly is, leaf-insects 

 occuring in several groups, but the only ref- 

 erence to leaf-insects in the text is on the 

 page facing this cut, where the Pliasmids are 

 said to be "composed of the walking-sticks 

 and the leaf-insects." There are over a hun- 

 dred illustrations. 



PROCEEDINGS OF THE CLUB. 



S October, 1897. The 197th meeting was 

 held at 156 Brattle St., Mr. S. Henshaw in 

 the chair. Mr. J. W. Folsom was chosen 

 secretary pro tern. 



Mr. S. H. Scudder showed specimens of the 

 huge Brachystola magna from Mexico, col- 

 lected a year or two ago by Dr. Edward Pal- 

 mer in Diirango. Dr. Palmer writes that 

 they are sometimes very destructive to corn 

 and beans, and if there is a deficiency of rain 

 when the plants are young these grasshoppers 

 feed on them because the grass is tough. At 

 the village of Magdalena. he adds, " I saw a
