Newm., Mag. Nat. Hist., 1870, p. 250], unknown to Haldeman 

 and Suffrian, has never been identified, so far as I know. It is 

 very distinct, by its coloration, from all other species of Pachy- 

 brachys. It is black, subopaque ; in the male, a frontal mark 

 oh the head and a stripe along the interior margins of the eyes, 

 the sides of the thorax and a great part of the anterior margin, 

 a large oblong spot on the anterior side of the front femora, 

 and a small spot near the base of all femora are whitish ; in the 

 female, the head and thorax are almost entirely black, and the 

 white spot on the anterior femora is wanting. Elytra red, with 

 a large common sutural spot, not reaching the apex, black. 

 Head densely punctured on the black parts, the white parts 

 almost smooth ; thorax on the sides densely, on the disc and 

 near the base less densely punctured, the white margins with a 

 few punctures or smooth ; elytra near the scutellum with irreg- 

 ular coarse punctures, in the other parts the punctures are 

 arranged in rows, often interrupted' and curved on the disc and 

 sides, more regular in the apical part. It varies in the exten- 

 sion of the white color on head and thorax, also in the size of 

 the elytral spot. In size it equals Pachybrachys luridus. It 

 occurs not rarely on oak scrubs, in the Indian River country, in 

 March and April. E. A. Schwarz. 



Insect Calendars. — For many years I have been in the habit of 

 keeping a catalogue of the times when insects may be found in activity, 

 that is, in the larval ami imaginal stages. My plan has been the following. 

 Each month is divided into quarters, indicated by Roman numerals, the 

 quarters of the months of 31 days ending on the 8th, 16th, 23d and 31st, 

 and those of the months of 30 lays ending on the 8th, loth, 23d and 30th. 

 These I call " weeks." In each " week " I record the species found in the 

 place of my residence ami adjacent localities during that week. An insect 

 which appeared in every week of the year would thus be recorded ibrty- 

 eight times (or not at all). The simplicity ami convenience of this method 

 fully rewards me for the labor of repeating the name so often. I attach to 

 each record a note of the authority upon which it rests, 'and sometimes, lor 

 convenience, a note of the first and last times of appearance of the insect 

 during the season. For this latter purpose, I call the last week of, lime the 

 24th week of the year, ami the last week of December the 48th week. 



Two examples will complete my statement. 



The only dates for A. pometaria thus far known to me are Oct. IV, Nov. 

 I, II, Ii!i, IV, Dec. I, II, III, IV, Jan. I, 11, Mar. IV, Apr. II, III, IV.
