(97) Meraporus (?) sp.—Fairly swarming in French section of Agricultural Build- 
ing in grain in sheaf, badly infested with Gelechia cerealella. 
(98) Meraporus sp.—Parasite of Bruehus 4-maculatus from Brazil. 
(99) Meraporus sp.—One other species, which has been referred to this genus by 
Mr. Ashmead, was found at large in the agricultural building. 
(100) Ateleopterus tarsalis Ashm.—Parasite of Silvanus surinamensis. Taken with 
its host in the exhibit of Argentine Republic. 
(101) Prosacantha sp.—In Spanish exhibit. 
All of the above are minute four-winged flies, the first six belonging to the family 
Chalcidid, the last two to the Proctotrypide. They are all more or less beneficial 
according to their abundance, serving in a measure to check the excessive multipli- 
eation of their injurious hosts. 
ECONOMIC IMPORTANCE OF SPECIES FOUND IN VEGETABLE PROD- 
UCTS. 
In the Coleoptera, the Clavicorn series, represented by Nos. 1 to 24, 
is composed largely of scavengers and predaceous species. Of the 
injurious forms not already introduced only No. 5 (Silvanus cassie ?), 
12 (the Cryptophagid ?), and 13 (Litargus sp.) are of importance, while 
the exact economic status of 24 (Ostoma pusillum) is doubtful. 
The species of the family Ptinide, which includes Nos. 25 to 31, are, 
with one or two exceptions, more or less injurious. No. 26 (Dinoderus 
sp.) is the only unintroduced species to be feared, although the further 
distribution of 25 (Dinoderus pusillus) would be undesirable. 
Of the family Bruchide or bean weevils (Nos. 33 to 49), the first seven 
are known to be injurious to beans, peas, or lentils, and 40 and 41 are 
probably so. A portion of these that are not known to live in this 
country were found only as dead specimens, and hence may not be able 
to live continuously in dried legumes. Those most to be feared are 37 
(Bruchus 4-maculatus) and 38 (B. chinensis), both already introduced, 
but as yet limited to the more Southern States. No. 48 (Spermophagus 
sp.) is not known to. occur here, and its introduction is not desirable. 
These three occurred in abundance at the Fair, and in their habits in 
living in dried beans resemble the common Bean Weevil. 
Of the Tenebrionid, the first six are meal-worms and injurious. Of 
these four species, viz, Palorus depressus, Gnathocerus cornutus, Echo- 
cerus maxillosus, and Tribolium confusum, have not yet been very exten- 
sively distributed through the United States, and their further dissemi- 
nation is to be avoided. 
The Rhynchophora or true weevils (Nos. 59 to 68) contain nothing new 
_ of importance. 
In other orders only the three grain moths—the Indian-meal Moth, 
the Angoumois Grain-moth, and the Mediterranean Flour-moth—are 
worthy of much consideration. The first two are cosmopolitan and 
the third is nearly so. 
To sum up, there is every probability that all of the species enumer- 
_ ated in the foregoing list as having been found in grain and other
