COLEOPTERA. Plate 8. 



The eleventh plate of this series is issued 

 with this number, and represents eleven 

 species of Geodephaga. We have thought 

 it would greatly assist the student to give 

 such anatomical dissections of each genus 

 as will serve to distinguish- one from another. 

 If the plates are cut up and the figures moun- 

 ted in proper scientific order, these dissections 

 should be placed at the beginning of each 

 genus. The following are the species fig- 

 ured on the present plate : — 



Ca/i'obus gldbratus — This insect is most 

 like O. violaceus, but is broader, the granula- 

 tions on the wing cases finer, and it is with- 

 out the violet margins. 



Bemhidivm fluviatile. — Cox gives this spe- 

 cies as " not uncommon," but we have never 

 taken it. It may be distinguished from lit- 

 torale and femoratum by the spots bting 

 larger and more distinct; from concinmm 

 by the spots not being united. All these 

 species have the thorax broader than long 

 and the posterior angles prominent ; in fluvi- 

 atile the thorax is as long as broad and the 

 posterior angles not prominent. 



Sem. artioulatum and rufescens are suffi- 

 ciently distinct to be at once recognised from 

 any other members of the same genus already 

 figured. 



PterosticMs vernalis. 



*Pter. nigHta. 



*Calathus mollis, — Avery soft insect, liable 

 to shrivel when dried (see Y.N. iv. 110). 

 Col flavi^es (see do.) 



Bradycellus verlasci. — Distinguished fiom 

 the next by the posterior angles of thorax 

 being obtuse. 



Srad. Mrpalinus, — Posterior angles of 

 thorax rounded. The insect has also a more 

 dumpy appearance than verlcisci.

Brad, similis. — Distinct enough to be re- 

 cognised. The red suture, or joining of the 

 wing cases, is a good mark. It is common 

 on moorlands. 



We have to thank several correspondents 

 for boxes of insects sent for figuring either 

 as presents or in exchange for others. Mr. 

 T. T. Morgan, of Liverpool, sent a small box 

 containing a "job lot," but, unfortunately, 

 many had got loose in transit and broken 

 both themselves and the others. 



The species marked thus * we have in 

 duplicate, and shall be glad to forward them 

 to any one desiring them as far as our stock 

 goes, especially those who can help us with 

 other species. We are preparing a plate of 

 A^Jiodius, and shall be particularly glad of 

 any species we do not possess. The following 

 are what we have : — 



* Apliodius ater 



„ cons^purcatus 



„ constans 



„ oontaminatus 



* „ depressus 

 „ erraticnis 



* „ fimetarius 

 , , f ceteris 



„ fossor 

 „ lividus 



* „ nitidulus 

 5, rufescens 

 „ riifipes 



,, scylalarius 



* „ sordidus 



,, s^iMerrajieus 

 Mr. Wilding of Liverpool has kindly sent 

 several of the above . 



QUERIES. 



35. 



Last July I had nearly all my broad beans 

 destroyed by a kind of green fly, which curled 

 up the leaves and turned them black. I shall 

 be much obliged if you can tell me the name
