Mr. Schwarz reported that on his recent visit to Texas he 
learned that the sweet-potato beetle (Cylas formicarius 
Fabricius) had been found in great numbers along the coast of 
Texas. This beetle came originally from Madagascar and has 
become introduced into tropical and subtropical portions of the 
western hemisphere. For some time past it has been known 
from Florida and Louisiana, but its discovery in Texas indi- 
cates that it is now to be found throughout the Gulf region 
from Florida to Texas and Mexico. Mr. Schwarz stated that 
he had found it particularly abundant in Cuba, but not so 
injurious there as elsewhere, since the common variety of sweet 
potato in that country has run wild and is a troublesome weed, 
the luxuriant vines overgrowing everything. The beetle is 
known to Cubans by the name "Tetuan," tradition having it 
that it first invaded Cuba in the same month and the same year 
when the famous battle of Tetuan was fought by the Spanish 
army against the Sultan of Morocco, February 4, 1860. 
Mr. Currie said that he had found another species of the genus 
very destructive to sweet potatoes in Liberia, West Africa, and 
Mr. Schwarz added that the Liberian species is probably Cylas 
turcipennis Boheman, originally described from Java. He said 
that there are about ten species known in the genus, all of them 
coming originally from tropical Africa or the Malay Archipelago. 
Dr. Hopkins stated that while investigating insect damage 
to hickory trees at Clark's Station, Missouri, on July 10, 1904, 
he found seven or eight small larvae attached to a Cerambycid 
larva (Neoclytus luscus] in the sapwood of a hickory tree killed 
by Scolytus ^-spinosus. The larvae were decidedly parasitic, 
and were supposed at the time to be braconid, but when (on 
July 20) they had completed the destruction of Jtheir host, and 
formed peculiar flattened cocoons, he recognized the cocoons as 
those of a beetle which he had often observed in the larval 
mines and pupal cases of Cerambycid larvae, and while at the 
West Virginia Station he had bred an adult. As near as he 
could remember, the bred beetle is a Colydiid, probably identi- 
cal with Bothrideres contractus. He says that there is no ques- 
tion regarding this larva being a true external parasite, as much 
so, indeed, as a braconid. A microscopic examination of the
