XORTH AMERICAN BOSTRICHIDAE 33 



short, erect, rather stiff, yellowish hairs on apical declivity, nearly 

 glabrous, and coarsely, densely, uniformly punctate on disk, densely 

 areolate-punctate on apical declivity, intervals smooth. 



Body beneath finely, densely granulose and shallovdy punctate, 

 sparsely clothed with moderately long, recumbent, yellowish hairs; 

 first segment of anterior tarsus not longer than the third or fourth 

 segment. 



Length 2.4-2.7 mm., width 1-1.2 mm. 



Type locality. — Of hifoveolatus, Madeira Islands: present location 

 of type unknown to writer. Of per punctata*, tropical regions (no 

 definite locality given) ; types in the Paris and Brussels Museums. 



Distribution. — This species has been recorded from all parts of the 

 world. It is cosmopolitan in the tropical regions, but is distributed to 

 the colder regions in commerce. Specimens have been examined from 

 many places in the United States, where it has been intercepted in 

 roots of derris. barbasco. cube. Jalapa, and Huira-Huira, and in 

 wooden packing cases. It will probably be found wherever these roots 

 are stored, but so far has not been reported infesting grains or cereal 

 products in the United States. 



Hosts. — Beeson and Bhatia (1937) recorded this species in Arto- 

 carpus hirsuta. Kydia calycina. and Mangifera indico,, and stated that 

 it is a wood borer, and in Africa bores into canes and palm leaves used 

 for making baskets and cases. Lesne (1921:) recorded this species 

 living in woody tissues, such as the stalks of Calamus used for making 

 baskets in New Guinea. It also lives in the ribs of leaves of the 

 Sago trees used in the construction of dwellings in Africa, and is 

 found burrowing in the dry roots of Manioc and yam. It is also 

 found in meals, principally yam, palm, and wheat. Miller (1934) 

 recorded it as being a well-known pest of grain. 



TTollaston (1858) described biforeolatus from eight specimens col- 

 lected at Funchal. in the Madeira Islands, in a barrel of flour, which 

 had remained about a year in the customhouse and had become spoiled. 

 Lesne (1895) described perpunctatus from the tropical regions, but 

 later (1898) placed it as a synonym of biforeolatus.
