278 BRITISH ICHNEUMONS. [Thymaris. 



and closely aciculatc throughout, with their apices usually pale. 9 only. 

 Length, 3^^ — 4 mm. 



In all other respects this small species resembles T. piilchricornis, 

 especially in having the apices of the three basal segments more or less 

 distinctly pale, the anus flavidous, the hind tibiae basally constricted and 

 the terebra centrally incrassate ; but the unicolourous flagellum, aciculate 

 third segment and small size will instantly distinguish it. 



I have met with it nowhere but on the windows of Monk's Soham 

 House, in Suffolk, where it has occurred to me upon several occasions in 

 June, August and September. It occurs along with Hem i teles cingulaior 

 and both appear to emerge from within the house, most probably bred 

 from Anobium domesticum, Corynetes caerulciis, or some other of our house- 

 hold insects.

 Thymaris fasciatiis, Bridg. Trans. Ent. Soc. 1886, p. 348, i . 



Head subbuccate and not contracted behind the finely pubescent eyes ; 

 clypeus apically rounded, mandibles centrally red and face normally 

 pubescent. Thorax black, with the mesonotum smooth and shining ; 

 mesopleurae dull, finely punctate and apically rugulose ; metathorax with 

 the lateral areae subobsolete, " the lower half with fine transverse rugae "; 

 areola apically incomplete, petiolar area transversely rugose and centrally 

 very slightly impressed. Abdomen finely pubescent, black with the 

 apical margin of the second, a band slightly beyond the centre of the 

 third and more obscurely of the fourth segments, red ; basal segment 

 slender with the postpetiole parallel- sided, distinctly impressed trans- 

 versely just behind its centre, nearly twice longer than broad and about 

 double the width of the petiole ; third segment rather longer than broad 

 and the remainder transverse. Legs slender ; the anterior pale red with 

 the coxae, base of trochanters and of femora black ; apices of the inter- 

 mediate tibiae and of their tarsi infuscate ; hind legs black with the cal- 

 caria, apex of trochanters, centre of tibiae and extreme base of tarsi 

 fulvescent. Wings basally pale ; tegulae black, stigma ochraceous ; 

 areolet wanting. Length, 7 mm. 



Bridgman brought forward this species among the Ophioninae, as hav- 

 ing no connection with Thyinarus and his description differs from the 

 present genus in the following particulars, which he ennumerates : — The 

 space between the eyes and base of mandibles about as broad as the 

 latter, the teeth of which are of equal length ; areola pentagonal and 

 rather broader than long ; the second segment twice longer than broad 

 and the nervellus not intercepted.
