ENTOMOLOGICAL SOCIETY OF WASHINGTON. 



January 12, 1899. — Under the head of exhibi- 

 tion of specimens Mr. Schwarz showed a true 

 queen of an undescribed species of Termes 

 which had been found by Mr. H. G. Hubbard 

 in the Madera Caiion of the Santa Rita Moun- 

 tains, Arizona. This is the first true Termite 

 queen which has been found in North America. 



Mr. Heidemann exhibited a species of the 

 genus Hoplinus found by Mr. Schwarz in south- 

 ern Arizona (Catalina Mountains). This is a 

 curious species thickly covered with spines, on 

 account of which Mr. Ashmead suggested that, 

 as the vegetation of that region is spiny, the 

 presence of this armatured bug indicated a case 

 of protective resemblance. A long discussion 

 ensued on the subject of mimicry and protec- 

 tive resemblance among insects, participated in 

 by Messrs. Gill, Ashmead, Judd and Howard. 



Dr. Dyar presented some notes on the phyl- 

 logeny of the Lasiocampid;e. Apropos of Mr. 

 Tutt's recent article on the subject he had gone 



over the group and established a genealogical 

 tree based principally upon the larval charac- 

 ters and the wing venation. , The discussion of 

 this paper took the form of a continuation of 

 the subject of protective resemblance suggested 

 by Dr. Dyar's remarks about the larvte of this 

 group of Lepidoptera, especially in relation to 

 the sub-lateral structures developed as a means 

 of eliminating the shadow cast by the caterpil- 

 lars, consisting in one group of larvae of a longi- 

 tudinal white line and in others of lateral pro- 

 cesses. Further discussion, by Messrs. Gill, 

 Ashmead and Dyar, considered the larval 

 characters of the Lepidoptera, Dr. Dyar stat- 

 ing that the most generalized larva is tubercu- 

 late, tubercules being lost and hairs being de- 

 veloped in the process of specialization. 



Mr. Schwarz read a paper by Mr. H. G. 

 Hubbard on the luminosity of a larviform Cole- 

 opter supposed to be the female of Mastino- 

 cerus, and supplemented Mr. Hubbard's note 

 by general remarks on the females of Lampyrid 

 beetles. Discussion followed, relating espe- 

 cially to the question as to whether luminosity 

 in the Lampyridas is a specialized condition, Dr. 

 Gill taking the stand that from its more or less 

 isolated occurrence in several groups of this 

 family it is more likely to have been an original 

 condition which has been lost perhaps by a ma- 

 jority of species in the process of specialization, 

 calling attention to the analogy between this 

 phenomenon in the Lampyridje and Elateridse 

 to the phenomenon of electricity in the fishes, 

 occurring as it does here and there in several 

 groups. Mr. Schwarz stated that the relation- 

 ship between the luminous Lampyridse and the 

 Elateridse was closer than perhaps has hitherto 

 been suspected and called attention to the fact 

 that the larviform female of Phengodes was 

 originally described by Le Conte as an Elaterid. 

 Mr. Howard considered that from the fact that 

 the species which lack this physiological quality 

 correspond to the normal coleopterous type and 

 that since the larviform females possess what 

 may be termed highly degradational characteris- 

 tics comparable to those acquired by a life of 

 parasitism, for example, the luminosity should 

 probably be considered a high specialization of 

 comparatively recent origin. 



The final paper of the evening was presented
