140 Termopsis Angiisticollis. [zoe 



with the species which was determined for me some time ago by 

 Dr. Hagen as Termopsis angusticollis . The specimens which I 

 had received previously had come from California only, although 

 I had received them from San Bernardino, lyos Angeles, and 

 Placer Counties." 



The following are the measurements of the specimens, includ- 

 ing another lot received about a week later: 



Soldier: From tips of mandibles to extremity of abdomen is 

 20 mm.; mandibles are 5 mm. long; body, from base of jaws, 16 

 mm.; body, excluding head, 11^ mm.; head is a little more 

 than 5 mm. wide. 



Worker: 13 mm. long; head, 3)2 to 373 mm. wide. 



Immature sexual ijidividiial: 13 mm. long; head, 3 mm. wide. 



The workers and sexual individuals are pale straw color; the 

 soldiers are same color, except that the head is more fulvous, 

 becoming darker anteriorly, and the jaws are black. Smaller 

 individuals than the above were also found. There were no 

 fully winged individuals at this season. 



This species is probably Termopsis angiisticollis, which, with 

 Termopsis oca'defifis, are the largest species of the family men- 

 tioned in Dr. Hagen' s synopsis of the Neuroptera of No. 

 Amer. (p. 3). The soldier described by Hagen under name 

 Termopsis occidentis is not this species, as suggested by Hagen 

 (1. c). The soldier of the present species does not have the pro- 

 thorax anteriorly emarginate, but nearly straight instead, and 

 the meso- and meta-thoracic posterior angles are not specially 

 produced. 



Termopsis occidentis Wlk. (soldier, body 14 mm.) is described 

 from the west coast of Central America. Dr. Hagen saw the 

 type. Termopsis angusticollis Hagen (sexual individual, body 1 1 

 mm.) is described from L/Ouisiana, California, and Puget Sound. 



These termites are said to make longitudinal galleries in the 

 Cottonwood trunks, more or less parallel, running irregularly up 

 and down, a couple of inches or so apart, and being about that 

 much in diameter. A section of a stick containing galleries was 

 brought me, from which I have taken the following measure- 

 ments:
