March, I9I2.] Wheeler: The Ants OF Guam. 45 



3. Odontomachus haematoda L. 



Seven workers and a winged female, all of rather small size (8- 

 9 mm.), but in other respects hardly differing enough from the typical 

 form of the species to be described as representatives of a distinct 

 subspecies or variety. 



4. Cremastogaster biroi Mayr. 



A single worker closely resembling Indian specimens of this 

 species in my collection. 



5. Monomorium destructor Jerdon. 



Six workers and four dealated females. This species is widely 

 distributed through the Indomalayan and West Indian regions. 

 ^ 6. Monomorium floricola Jerdon. 



Several workers, females and males. The females are wingless 

 and subergatoid as I have shown to be the case in West Indian speci- 

 mens of this tropicopolitan ant. 



7. Cardiocondyla emeryi Forel. 



/ A worker and male. This species is also widely distributed, occur- 

 ing in the West Indies, India, Madagascar and Palestine. 

 8. . Solonopsis geminata Fabr. subsp. tufa Jerdon. 



Numerous workers and males. This is the paleotropical form of 

 the well-known " fire ant," originally described from tropical America 

 and in this region presenting many different subspecies and varieties. 

 It is unquestionably this species to which Safford refers in his volume 

 on the useful plants of Guam^ when he says : " These little creatures, 

 when out on foraging expeditions, travel in lines and sting every 

 animal that crosses their path. Sometimes young chickens are killed 

 by them. They are common in houses, and it is not unusual on 

 turning in at night to find a line of them crossing the bed." 



9. Pheidole javana Mayr. 



Two soldiers and two workers of the typical form of the species, 

 which seems to have a wide distribution in the Indomalayan region. 



10. Pheidole sp. 



A single small, black worker with densely punctate head and 

 thorax, not accompanied by the soldier which alone would permit of 

 more accurate identification.
