(Pag. 33G.) 2. M. subopaca [= Micaria gub-opaca Westr. 1861]. 



Of this species I have seen but one specimen, that which served 

 as type for Westring's description. It is a fullgrown male, shrunken 

 and pasted on a piece of cardboard, so that only the upper side is 

 accessible to examination. One however immediately perceives that 

 it is a peculiar species, completely distinct from M. pulicaria. The 

 cephalothorax is scarcely 1 millim. long, the whole body 2 millim.; 

 the anterior row of eyes is only slightly curved , the two anterior cen- 

 tral eyes , which are almost in contact with the anterior lateral eyes , 

 are not larger than, but at the utmost equal in size to these latter. 

 With M. nitens L. Koch ') M. sub-opaca cannot be identical, for in 

 the former the anterior row of eyes is said to be strongly curved 

 forward, the anterior lateral larger than the anterior central eyes, 

 and the tibiae of the 1 st pair armed on the under-side with 2 rows 

 of very short spines, of which I see no traces in M. sub-opaca. On 

 the thighs of this spider I cannot with certainty discover more than 

 one very fine spine. The palpi are somewhat shorter than in M. 

 pulicaria cf; the length of the tibial joint is not greater than its 

 breadth, the spine at its extremity is slightly curved upward, and 

 longer than in M. pulicaria; the tarsal joint (lamina bulbi) is oval, 

 and its length not more than double its breadh (in M. pulicaria it 

 is longer and slenderer) ; on the outer side of the clava may be seen 

 a fine spine directed obliquely forward and outward, issuing from 

 the bulbus. Compare Westring's description 2 ).

2) The following description of a large and, as it seems, hitherto unde- 

 scribed Micaria, M. ctnea N. may be inserted here: 



Micaria anea N. Nigricans , squamulis minutis virescentibus nitidis tecta, 

 abdomine fascia media transversa angusta albicanti, pedibus ad maximam partem 

 luteo-nigricautibus. — J o,d. Long. c:a 5 millim. 



Cephalothorax inverse ovatus, c:a 2 millim. longus (= patella + tibia ped. 

 4:ti paris), fere IV2 millim. latus, lat. frontis dimidium latitudinis maxima? ce- 

 phalothoracis non superanti, nigro-fuscus, postice paullo clarior, squamulis minutis 

 pallide virescentibus, purpureo-micantibus vestitum. Oculorum series postica de- 

 super visa parum procurva, fere recta, oculis mediis longius inter se quam a late- 

 ralibus remotis; series antica fortiter procurva, oculis lateralibus paullo majoribus 

 quam sunt medii. Mandibulae sub-cylindratae, tibiis anticis vix crassiores, pilosae, 

 non squamosa?, cum maxillis et labio nigro-fusca?. Sternum nigricans, pilosum, 

 non squamosum. Palpi nigro-testacei , parte femorali nigricanti. Pedes ad maxi- 

 mam partem nigricanti-lutei , femoribus an', erioribus prasertim et metatarsis ob- 

 scurioribus, nigricantibus , patellis tarsisque clarioribus, coxis posterioribus testa-
