tate, the punctures arranged in more or less distinct rows on disk, 

 but sometimes becoming obsolete on apical declivity towards apices. 



Body beneath finely, densely punctate, sparsely clothed with very 

 short, recumbent, yellowish hairs; last visible abdominal sternite 

 densely clothed with long, yellow hairs at apex. 



Female. — Differs from the male in not having large, arcuate 

 tubercles on the apical declivity of the elytra. 



Length 6-13 mm., width 2.2-3.5 mm. 



Type locality. — Of aequalis, Timor Laut Islands ; present location of 

 type unknown to writer. Of uncipennis, many localities — Indo- 

 China, Southern Hindostan, Madagascar, and the Andaman and 

 Marianne Islands ; types in the Paris and Brussells Museums. 



Distribution. — This species is widely distributed throughout India, 

 Ceylon, Indo-China, Federated Malay States, Java, Philippines, New 

 Guinea, Madagascar, and many of the Malaysian Islands. It has been 

 intercepted a great many times at New York, N. Y. ; San Francisco, 

 Calif.; Dallas, Tex.; Allentown and Philadelphia, Pa.; and New 

 Orleans, La., in wooden packing cases and Philippine mahogany, from 

 India, Java and the Philippines. So far as known, it has not become 

 established in the United States. 



Hosts. — Beeson and Bhatia (1937) record the following host plants : 

 Adina cordifolia, ATbizzia stipulata, Anisoptera glabra, Bambvsa 

 arundinacea, Bombax anceps, B. insigne, B. malabaricum, Boswellia 

 serrata, Canarium euphyllum, Cassia fistula, Cedrela toona, Dalbergia 

 sissoo, Dendro calamus strictus, Dipterocarpus pilosus, D. turbinatus, 

 Endospermum Chinese, Garuga pinnata, Koompassia malaccensis, 

 Kydia calycina, Lannea grandis, Leucaena glauca, Mangifera indica, 

 Morns indica, Parashorea stellata, Parishia insignis, Poinciana elata, 

 Pterocarpus indicus, Quercus sp., Shorea leprosula, S. robusta, Ster- 

 culia alata, S. campanulata, Tectona grandis, Terrrdndlia belerica, T. 

 bialata, T. myriocarpa, T. tomentosa, and Anogeissus acuminata. 



In India this is the commonest of the larger bostrichid beetles found 

 boring in packing cases, boxes, plywood, chests, sapwood in furniture, 

 and in sal (Shorea robusta) rafters of the thatched bungalows, and is 

 a regular pest in sawmills and factories of wood-using industries. The 

 beetles will bore through 1 to 2 inches of wood and make holes in the 

 lead lining of boxes. When logs are heavily attacked the wood is re- 

 duced to powder to a depth of 2 to 3 inches. 



The emargination on the anterior margin of the pronotum is quite 

 variable in shape, arcuate, angulate, trapezoidal, and sometimes not 

 very distinct. The posterior angles of the pronotum are rectangular, 

 sometimes prolonged into a rounded lobe. The tubercles on the apical 

 declivity of the elytra in the male are variable in shape and length, 

 sometimes the outer one is represented by a rounded knob and some- 

 times by a short costiform tubercle, and the inner tubercle is variable 

 in length and sometimes more robust and more strongly hooked. 

 Sometimes the female has two more or less distinct costiform tubercles 

 on the apical declivity of each elytron. The punctures on the apical 

 declivity of the elytra are variable in density, sometimes as dense in 

 the males as in the females. 



Lesne (1895) described uncipennis from both sexes from many dif- 

 ferent localities, in various European collections, without designating
