emerges at niglit from holes and cracks in the walls. One day in 

 March, after a slight rainfall, several dozen of these beetles were 

 connted crawling from holes in the ground near the base of an adobe 

 wall in one of the streets of the town. Determined by Dr. Skinner. 



Fyrota postica Lee. — This large black and yellow Meloid occurs very 

 numerously on Larrea mexicana, or Creosote Bush, particularly on the 

 iiowers. Determined by Dr. Skinner. 



2Iyodites nevadicus Lee. — Two specimens of this Stylops-like beetle 

 were taken on flowers in May and June. I am strongly of the opinion 

 that this is the adult of a parasite which I have taken from the abdo- 

 mens of our common yellow social wasp, PoUstes aurifer. Determined 

 by Dr. Skinner. 



Eupagoderes decipiens Lee. — Beaten May 10 from flowers and foliage 

 of Mosquito {F.juUflora). Whether or not they breed in this shrub, it 

 is certain that they feed on it in the perfect state. The jaws of each of 

 three specimens taken were gummed with the greenish chlorophyll upon 

 which they had evidently been feeding. These beetles were infested 

 with red mites. Determined by Dr. Skinner. 



Pandeletejus cinereus Horn. — Beaten in large numbers from Mesquite 

 (P. juliflora), May 12 and later. It was noticed hi coitu May 16. It 

 may breed in the Mesquite pods. Determined by Dr. Eiley. 



FURTHER NOTES ON THE NEW HERBARIUM PEST. 



By C. V. Eiley. 



My friend Mr. E. McLachlan, of Lewisham, England, has kindly 

 called my attention in connection with the article on ^'A ]N'ew Her- 

 barium Pest," Insect Life, vol. iv (pp. 108-113), to the fact that a 

 similar insect, viz, Acidalia herhariaia Fab., has long been known to 

 injure herbarium specimens in Europe, but is perhaps more injurious- 

 in herbalists' shops than in museums, and that the figure of our 

 American insect looks a good deal like it. 



The de8Cvi]^tions of Acidalia lierhariata show it to be allied to Car- 

 phoxera ptelearia, but, nevertheless, when carefully compared, the two 

 are found to be very different structurally. Dr. F. J. M. Hylaerts 

 gives, in the Annales de la Societe Entomologiqtie de Belgique^ 1878 (voL 

 XXI, pp. o-^)^ the fullest descriptions accessible of the larva and pupa 

 of A. herbariata, and notwithstanding the minuteness of the descrip- 

 tions, no mention is made of the structural characters to which I called 

 attention, both in the larva and pupa of Oarphoxera. The colorational 

 marks are also quite different, though in this respect, so far as the 

 larva is concerned, they are admitted to be quite variable. Acidalia. 

 piisillaria Hiibner (Samm. Eur. Schm., Geom. Fig. 99) and J., micro- 

 saria Boisd. are sjmonyms of lierhariata^ Fabr., and neither of these
