ENTOMOLOGICAL NKYVS [xXXl'i. '21 



Outside of a fairly large number of species apparently undescribed, 

 the best species collected in beetles were two extremely rare tiger 

 beetles, Cicindela nci-adica at Ash Meadow, Nev., and Cicindela paro- 

 wana near Parowan, Utah. Many large series were taken and much 

 new material will be added to Mr. Knaus' collection, which will eventu- 

 ally go to the State Agricultural College. The material that goes to 

 McPherson College will virtually lie the beginning of their entomo- 

 logical collection. The Democrat-Opinion, McPherson, Kansas, Sept.

The Thread Worm Gongylonema hominis Introduced into Man 



by Insects? 



Prof. C. W. Stiles, of the Hygienic Laboratory of the U. S. Public 

 Health Service, reports the discovery of a new case of Gongylonema 

 infection in man. 



The first known case was reported by Ward (1916) from Arkansas, 

 where the thread-like nematode was taken from the lower lip. The 

 second, also taken from the lip, was reported by Stiles (1917) from 

 Florida. The present case was found by Stiles in the practice of Dr. 

 H. L. Akridge, of Sale City, Ga. 



The patient, a woman of 50, consulted Dr. Akridge for sore throat 

 that had lasted about three weeks. He found an abrasion of the 

 mucous membrane around the anterior pillar of the tonsil and another 

 near the angle of the jaw. Both were very sensitive. He touched 

 them with 10 per cent silver nitrate solution and gave the patient a 

 mild antiseptic mouth wash and a purge of calomel. Three days later, 

 examination showed another abrasion on the opposite side of the 

 mouth about an inch anterior to the angle of the jaw. He again ap- 

 plied silver nitrate and gave the patient a mouth wash containing a 

 strong solution of thymol. The next day she came back with the 

 worm. She had felt it partly out in her mouth and had been able to 

 pull it out with her fingers. It lived for several hours in water. 



When Prof. Stiles saw the specimen it was badly macerated. How- 

 ever, a fragrant of the cuticle showed two of the "bosses" that char- 

 acterize the head end of Gongylonema; and the pharynx excluded the 

 Loci worm from consideration. The worm was about 35 millimeters 

 long. 



The case emphasizes the fact that a parasitic infection of man, 

 widely distributed (Florida, Georgia, Arkansas) but seldom recognized, 

 exists in the United States. The infection doubtless occurs through 

 swallowing insects, perhaps croton bugs. It causes irritation and ner- 

 vousness but apparently no dangerous condition. 



Similar infections are widespread among cattle, sheep, rats, etc. ; and 

 the form in man may be specifically identical with one of these. 

 Until material is available to establish identity, Prof. Stiles suggests,
