10 INSECTS AFFECTING STORED PRODUCTS. 
The other stages of this species were not described for lack of time 
when specimens were fresh and later these were not in condition for 
specific description. 
THE LARVA. 
The larva illustrated at b of figure 1 is elongate subcylindrical, 
about six times as long as wide. It is gray, each segment being darker 
at the middle, while at the sides of each of these darker spaces there 
are rather well developed piliferous tubercles. An enlarged leg is 
shown at d and an antenna, also enlarged, at e. When full grown 
the larva measures about five-sixteenths of an inch (8.5 mm.) in 
length. 
THE PUPA. 
The pupa (fig. 1, c) is about the same size as the adult, paler than 
the larva, nearly white. It will be noticed that the thorax bears 
conspicuous long hairs and that similar hairs project from tubercles 
on the abdomen. In the pupa as well as the larva the anal apex 
terminates in two divergent points. 
It should be added. that both larva and pupa are delicate and per- 
ceptibly softer than the common grain-feeding tenebrionids found 
in similar locations. 
LITERATURE. 
The literature on this species is decidedly scanty. The original 
description appeared in 1875. * This was followed by two records 
of the finding of the insect in cotton bolls from Bahia, Brazil, one in 
1880, 2 when it is mentioned as "(4) one specimen of a Diploccelus 
not occurring in the United States," and again in 1885 as follows 3 : 
' ' (4) one specimen of a cryptophagid beetle, apparently undescribed 
and not occurring in the United States." Mr. E. A. Schwarz, who 
saw the specimen referred to, assures the writer that it is this species. 
In the collection of the United States National Museum there are 
also specimens bearing this label: "In corn, Guatemala, March 24, 
1884." 
Brief mention was made in 1894 5 of the occurrence of this species 
in exhibits of stored products, the insect being referred to as a 
''Cryptophagid (?)" with the statement that it was found living in 
corn meal and edible tubers from the Mexican and Guatemalan 
exhibits at the World's Fair held in Chicago in 1893. The following 
year 6 this species was included in a list of foreign insects introduced 
into the United States in recent years. In 1896 7 similar notes were 
published in a list of insects known to occur in stored products in 
Mexico and record was made of the capture of the species near San 
Antonio, Tex., in December, 1S95. 
In all, this species has received ten notices, none of them extensive, 
the remainder, which will not receive mention, being descriptive and 
synonymic al articles and notes.
