sides is dark brown tinp'tl with n-cl, and the lateral niarf;;iii.s 

 liave a bntwnisli-hlac-k line. Tlio talci's arc soniowliat conu-al, 

 vertical, and of a pale dull-ycll<>wisli hue. The maxilla' are 

 inclined towards tlu' lip, ronndeil at the extremity, which is 

 more abruptly curved on the inni-r than on the outer side, and 

 are rather darker-coloured than the talces. The lip and the 

 sternum are oval, glossy, and of a dark-browiv colour tinged 

 with red, the former being much the palest at the apex. iMic 

 legs are ratiier short, and of a ])ale-yellowish hue, with reddish- 

 brown annuli ; tin- first ])air is the longest, then the second, 

 the third i)air is the shortest, antl the metatarsal joint of each 

 posterior leg is ])rovided with a calamistrum composed of a 

 single row of tine curved bristles ; the palpi resemble the legs 

 in colour. The abdomen is oviform, convex above, projects 

 greatly over the base of the cephalothorax, and is clothed with 

 whitish adjircsscd hairs ; its colour is yellow ; a black band, 

 very naiTow at its anterior and broad at its posterior part, 

 passes from the anterior extremity to the middle of the u])per 

 side, and is followed by transverse, curved, confluent, blark 

 bars, which extend to the coccyx ; the sides have a brownish- 

 black hue, the under is paler than the upper side, and has a 

 broad, imjjerfectly defined, longitudinal, reddish-brown band 

 in the middle. The spinners are eight in nimiber, and the 

 two inferior ones are united throughout their entire length, 

 the ])roximal extremities being without any definite mark of 

 distinction. 



This species is closely allied to Ergatis anniihpes, but dif- 



rs from it in colour and 

 upper part of the abdomen.

This species has an extensive geographical distribution, 

 being found in Europe, Asia, and America. It is probably a 

 native of hot climates, as in Europe it usually inhabits con- 

 servatories, and may have been imported, as Koch conjectures, 

 with exotic plants. A specimen of an adult female, comprised 

 in the collection received from Miss Hunter, was discovered 

 in winter between the sashes of one of the double windows of 

 the house in which she resided.
