12 THE FAUNA OF SCOTLAND. 



6. T. LACHLANiANA, Cam., sp. n. 



T. nigra, ore, orbitis oculorum, linea pronoti, maculisquc 2 supra coxas 

 j)Osticas, albis; ahdomine medio rufo, pedihus rufis, femoribus anticis basi, 

 posticis fere totis nigris; alis hyalinis, casta et stigmate paMide fuscis. 



Long 5-6 lin.; alar exp. 11-12 lin. 



Black, mandibles, labium, clypeus, inner orbits of the eyes, a triangular 

 spot between the antennae; tegulae, the edge of the pronotum, and two 

 spots over the posterior coxae, white; the middle abdominal segments 

 broadly banded with red, the apices of the four anterior femora, and the 

 tibiae and tarsi pale red; the thorax opaque, the head and abdomen 

 shining; the wings hyaline, the costa and stigma pale fuscous. 



Length, 5-6 lines, alar exp. 11-12 lines. 



Very similar to T. moniliata, Kl. (with which it is no doubt confounded), 

 but it may be readily known from that species by having the inner orbits 

 of the eyes, and a spot between the antennae, white, the posterior femora 

 quite black. The markings on the head and thorax are white — not yellow, 

 and the posterior tarsi and the apex of the tibae are not marked with 

 black. It has also two marks over posterior coxae, while King's species 

 has only one. 



In one of my Scotch specimens the red abdominal band is very obscure, 

 and two others have only one side of the pronotum white. Generally the 

 3d, 4th, and 5th abdominal segments are red. 



This species was captured by myself in June at Eannoch, Perthshire, 

 and I have also seen in the collection of Mr R. M'Lachlan, F.R.S. (after 

 whom I have named it), a German specimen taken by Prof. Zeller.
