PSTCHE. 



[November 1S01. 



Cicindela purpurea is very common 

 in dry pastures. C. hirticollis is rare.* 

 C. sexguttata, & 2 varieties, one with 

 an additional spot on the disc, the other 

 without the terminal one, are found in 

 sandy paths. The habitat of punctu- 

 lata is the same. Elaphrus riparius 

 is rare Carabus catenulartus is" scarce. 

 Agra pensylvanlca I have found be- 

 neath stones on sunny banks. Omo- 

 phron limbatum Latr. inhabits near 

 fresh water streams ; Dytiscus margin- 

 alis in stagnant water. Several other 

 species of Dytiscus, are found, but I 

 have not made out the species. We 

 have a Buprestis which appears to be 

 the virginiensis, but my specimen has 

 not the metallic lustre of yours. Elater 

 oculatus is common ; I have not ascer- 

 tained the habitat of its larva. We 

 have your E. dorsalis, & E. corticinus. 

 Lycus dimidiatus & L. reticulatus are 

 generally taken on the wing in the day 

 time, about bushes, & hedges. Mala- 

 chius 4-maculatus? the male is distin- 

 guished by having the 2d joint of the 

 antennae (not the 3d joint, as in Fabri- 

 cius) dilated, quadrate, & with a deep 

 indentation. But what is most remark- 

 able is that, even by aid of a powerful 

 magnifier, I could detect only 4 joints 

 to the anterior tarsi. Like others of 

 the genus this species is furnished with 

 with 4 retractile, tridigitated tentacula? 

 or processes, one on each of the thorax 

 & abdomen. Having fixed my speci- 

 men to a card I cannot compare the 

 colours beneath with those of your

 seen. 



vittatus ; but those of the superior sur- 

 face correspond exactly, except the an- 

 tenna, the first and 2d joints of wh'h 

 are rufous, the remainder blackish. 

 Length of the male just A inch. The 

 female has the usual number of joints to 

 the anterior tarsi. There some varieties 

 particularly of this sex : In these the 

 thorax is destitute of the black spots ; the 

 dilated humeral portion of the margin is 

 extended into a fascia which unites with 

 the suture. This species of Malachius 

 I have found in meadows, on the flowers 

 of Chrysanthemum leucanthemum, in 

 June & July. We have several species 

 of Ips which are allied to the fasciata. 

 Attagenus pelllo is very common in 

 houses, & a species, or perhaps variety, 

 without the white dot on the elytron. 

 I have met with a Lucanus which 

 corresponds with your parallelus, only 

 that there is no small tooth "on the 

 middle of the inferior inner edge" of 

 the mandibles. Passalus interrup- 

 tus is common. Diaperis macztlata 

 Oliv. is found here upon fungi. 

 Three species of Lytta are also found 

 here, viz: L. cinerea on the potato-vine 

 &c, L. marginata on the Clematis 



virginiana, & L. atrata on the Solid- 

 ly 



ago. Bruchus pisi prevails every year. 

 We have your Lamia aspersa, also L. 

 nebulosa F. and Callidiuj)i bicolor, F. 

 I will now recur to the insects which 

 I sent you in box 1. If No. 2 be Calo- 

 soma calidum of Fabricius (which I 

 presume you intended when you wrote 

 calida) that author was mistaken in 

 describing it as apterous ; all the speci- 

 mens which I have seen certainly have
