180 TRANSACTIONS OF THE [mAY 5, 



I was glad to read in your last that Dr. Hagen modifies his 

 assertion relative to several species occupying the same nest, and 

 that my explanation agrees with Fritz Miiller's. I have the two 

 species at work together in two glass jars with a bridge connec- 

 tion^ and they both have built an independent gallery on the 

 underside, and this is a curiosity. 



July 4th, 1889, This morning, while probing the cocaloba 

 tree on the beach, my knife entered a cavity and exposed a 

 household of termites, — two sexual individuals, with a family of 

 eight small larvae. I hurried them into my termitarium to make 

 an examination, and believe that I have father, mother, and eight 

 children — larvm. What a find! They had evidently just com- 

 menced housekeeping and are Nasutitermes (Eutermes). Their 

 little house was an excavated globular cavity, about three-eighths 

 of an inch diameter, in the thickened, gnarled bark. At first I 

 could not believe the little ones belonged to them, but as soon as I 

 put them on a saucer with a small chip of the bark, they both picked 

 up the little ones on the chip and commenced to wash them; that 

 decided the relationship. I prepared an ash block by making 

 an excavation and placing in the bottom a piece of their tree- 

 nest, being careful not to touch it with my fingers and so destroy 

 the smell of their old home; and they now have the choice of a 

 bark or ash cell with a glass roof, and have taken possession and 

 seem contented. The images are about seven mm. in length, two 

 and one-half mm. diameter. One has a white longitudinal stripe 

 on the sides of the abdomen, the other has a yellow stripe, and 

 the latter seems to be the male. Otherwise they look alike, and 

 on my last view of them they were both washing the babies. Is it 

 possible these eight larvse, one and one-half mm. long, are from 

 the first eggs laid, and then a rest ? I await further observations 

 of them with great interest. 



This morning at 4 o'clock I looked at my blocks of termites 

 and found a nympha with short wing-cases had just cast its 

 skin, and I mounted it. You see they have to be constantly 

 watched to find them in the act of moulting, and I desire to see 

 those with the long wing-cases moult, to note the difference in 

 appearance afterward.
