NOTES ON THE COLEOPTERA WITH DESCRIPTION OF 



NEW SPECIES. 



BY C. A. FROST. 

 Framingham, Mass. 



(Continued from page 232.) 



Chrysobothris verdigripennis Frost. My type material was taken at 

 Wales, Maine, on July 23, 1908, and fortunately included both sexes and the 

 extremes of colour variation. Considerable study was given the series the 

 following winter, and the characters were carefully worked out so that it was 

 apparent that an undescribed species was at hand. After this, spec'mens were 

 submitted to Mr. Blanchard who made further investigations, and to whom the 

 entire series was sent for a description of the species. He delayed this for some 

 months, and when he suggested turning it over to another specialist, I requested 

 the return of the specimens and finished my investigations. 



Since the description (Jour. N. Y. Ent. Soc, Vol. XVIII) I have seen but 

 one living specimen, which was resting on the trunk of a lone hemlock in a 

 small clearing at Monmouth, Me., July 18, 1915. I approached too cautiously, 

 and as it took wing the net missed it by an inch. He who would capture this 

 agile and watchful insect must be quick and sure, for it tarries not. I recall 

 that the original series were resting on beech trunks in the hot July sunshine, 

 and after losing several I tried making a quick leap, thrusting the net below 

 them and smashing down on them with my hat or a bunch of ferns as they rose; 

 This method resulted in sweeping some of the specimens into the net. 



I have also seen one specimen from Connecticut, two from Le Pas, Manitoba, 

 (J. B. Wallis), one from \ermont, and a typical male from Port Maitland, 

 Nova Scotia, August 2, 1910. A male I retained from the two Manitoba speci- 

 mens (July 3, 1917) is only 11 mm. in length and a of dark bronze colour, but 

 otherwise typical. Mr. A. S. Nicolay writes me that he has one from Lake 

 Superior, and another from the Catskill Mts., New York, August 14, 1889. 



Agrilus lateralis Say. The capture of a pair of this species by Mr. C. W. 

 Johnson at St. Augustine, Fla., April 21, 1919, seems to add a new section of 

 the country to the already wide distribution of this rather uncommon insect. 

 The female of this pair is unusually large, 9.4 mm. It has been recorded from 

 Maine (Wales, June 23, 192) to New Mexico. 



Agrilus champlaini Frost. Since the description (Can. Ent., 1912) the 

 male holotype has been deposited in the collection of the State Agricultural 

 Experiment Station at New Haven, Conn. The female allotype and a typical 

 male are still in my collection. The remains of an Agrilus that strongly re- 

 sembles this species were dug, together with a dead Saperda obliqua, from a 

 gall on Alnus incana at Framingham, Mass. The gall appeared to have been 

 mainly the work of the Saperda. Champlaini was described from specimens 

 reared from galls on the twigs of Ostrya virginica. 



Agrilus criddlei, n. sp. Form of a«:x;iW5, less elongate, olivaceous bronze, 

 with bluish reflections^ slightly shining; antennae reaching beyond the middle 

 of the thorax, serrate from the fourth joint, greenish bronze; front slightly 

 concave, greenish, occiput very slightly impressed, median line reaching middle 

 of front, surface with coarse, rough punctures irregularly confluent. 



November, 1920
