Panama, by Dietz and Zetek. 
leucotermes convexinotatus 
The other species, Leucotermes convexinotatus , was first found tunnelling 
the woodwork of buildings in Colon by engineers of the Western Electric 
Co. in 1914. 
At Colon, Republic of Panama, this termite was taken from tunnels in 
sweet potatoes on October 25, 1918, the injury to this host superficially 
resembling that of the sweet-potato weevil, Cylas formicarius Fabricius. 
Banana stumps were found riddled by it at Matias Hernandez, Republic 
of Panama, on October 29, 1918. In the Las Sabanas region of Panama 
convexinotatus has been found living as an inquiline or “ social parasite ” (?) 
(22) in the outer parts of all the large nests of Amitermes medius that 
were opened. 
On February 11, 1920, Mr. Zetek found specimens of workers and 
soldiers of Leucotermes convexinotatus at Panama City infesting young 
avocado trees received from Cuba and planted the day after receipt. 
Injury was first noted a month or so after planting. It was thought 
that the termites came with the ball of dirt which was around the 
plants, since nests were found in it. Species of Leucotermes (L. con- 
vexinotatus and L. cardini Snyder) occur in Cuba, but the specimens 
were not necessarily imported, since these termites are injurious species 
in Panama. 
L. convexinotatus was found by Zetek on February 11, 1921, at El 
Retiro, Rio Abaja section, Las Sabanas, near Panama City, mining 
sugar cane. 
On May 4, 1921, Messrs. Zetek and Molino opened a mound nest of 
Amitermes medius at Las Sabanas, the galleries of which, were crowded 
with winged forms of Leucotermes convexinotatus . Soldiers and workers 
of L. convexinotatus were also present and seemed to dominate the upper 
and middle portions of this nest of Amitermes. Apparently either 
species of Leucotermes lives peacefully with Amitermes until human 
beings disturb the nest, upon which the two species engage in combat. 
On May 13, 1921, Messrs. Zetek and Molino found workers and soldiers 
of L. convexinotatus in the roots of a dying young citrus tree at the Summit, 
Canal Zone, plantation. The termites were very abundant in the field 
and dead wood lay about freely. 
SWARMING 
Leucotermes convexinotatus apparently swarms during the same season 
as does L. tenuis. Immature winged adults were collected at Colon, 
Republic of Panama, on April 11, 1914, in the woodwork of the cable 
office. 
On May 4, 1921, winged adults were found in an Amitermes nest at 
Las Sabanas, as described above. These adults were mature and ready 
to swarm. On May 3 and 4, 1921, Mr. Zetek collected winged adults 
of this species swarming at Panama City in the dining room of a dwelling 
house. These were abundant and were flying with adults of Anoplo- 
termes gracilis . 
Winged termites of L. convexinotatus were collected in Mr. Zetek's 
dining room in Panama City, around a 60-watt electric light, at about
