J^SYCHE. 



okl stump, was sifted over on May 29, 

 and from it I obtained Adraiies lecon- 

 tei, Ceophyllus vionilis and Limulodes 

 paradoxtis. 



VI. Tapitioma sessile Say. This 

 species is very common near Iowa City, 

 i3ut seems hut very little favored by 

 guests. I have a record of Connophro7i 

 longipeitne taken with it, April 17, 

 but the occurrence is probablj- acci- 

 dental. 



VII. Poncra painsvlvai/ica ]3uck. 

 Frequently met with, but I have nn\\ a 

 single record. Coiitiophroii clavicorin\ 

 found with, this ant, April 17. 



VIII. Aphaeiiogaster aqiiia HucU. 

 Nests in the ground, the galleries open- 

 ing in the protection of a stone or piece 

 of wood, the latter often much pierced 

 by the tunnels. During April and May, 

 Linuilodes paradoxus occurs abun- 

 dantly with this species, and the little 

 beetles may" lie seen running around 

 among their hosts without any moles- 

 tation whatever. 



IX. Pogononi\'i'?ncx opaciceps May r. 

 Specimens of this ant were sent me 

 from the neighborhood of Denver, 

 Colorado, by Mr. Ernest J. Oslar, who 

 writes that it is the host of Crcmasto- 

 chilits sa/ic/'ns and C. knochii, speci- 

 mens of which I have also received 

 from him. He finds the beetles with 

 their hosts at various times, my ex- 

 amples of sa?icius being dated E. 

 Denver, April 10, Berkeley, June 3, 

 and Salida, ful)' 11. The knoc/iii iwc 

 marked Berkeley, April 8, and Chim- 

 ney Gulch, June [S. He savs of san- 

 c/'iis: " I generally find it in anthills 



but never more than one in each, at all 

 times of the year. Last winter, just 

 before Christmas, a friend and myself 

 drove to a place called Parkers, twenty- 

 five miles south of Denver, on a three 

 days' jack rabbit hunt, while a foot of 

 snow lay on the ground. I kicked up 

 four saiicitis from the ant hills during 

 the three days of our hunting. Of 

 course the\' were dormant, and I carried 

 them in an empty cartrirlge shell. By 

 the time I got back to Denver they 

 were all lively from the warmth of my 

 pocket." I notice that it is ditlicult to 

 get perfect specimens of this beetle, the 

 legs often being much nnnilated, sup- 

 posedlv b\- the ants which are large 

 and fierce creatures. 



X. Plicidole vhilandica Forel, 

 (name from Rev. P. Jerome Schmitt). 

 From a nest of this species I got a single 

 specimen uS. At inns monilicoriiis. The 

 colon\ was hnused under a large stone, 

 by the roatlside. in the vicinity of Nash- 

 ville, Tennessee. The date was aliout 

 the middle of August. 



XI. Cremastogaster olinelata Say. 

 Although this is one of our commonest 

 Iowa ants and occurs in great colonies, 

 I seldom find any beetles with it except 

 such as are clearly casual companions. 

 I have, however, a record of Pycno- 

 plnis rasiis vyhich may be worth saving. 



All of the foregoing notes are to be 

 considered as referring to observations 

 made near Iowa city, unless otherwise 

 stated. I wish to express my thanks 

 to Mr. Theo. Pergande and to Rev. P. 

 Jerome Schmitt foi kind aid rendered 

 in the way of identifications.
