Mr. Haliday has observed to me, in a letter, that this genus 

 affords two strongly-marked divisions, — 



L With the interior brachial cell of the lower wings emitting 

 a single nervure from its inner angle. 



1. M. Tipularius Grav. 2. 964. 332.— Curt. Guide, 508. 332. 



In larch plantations, Galway, Mr. Haliday. 



2. M. splendidulus Grav.- — Very rare at Belfast, but common in Galway. 



3. M. olerum Hal. — Length If line. Black, lower part of face, orbit of 



eyes, posterior margin of 2nd segment of the abdomen, a spot at 

 the base of the 3rd, and the legs, ochreous : tips of posterior tibiae 

 and tarsi fuscous. 

 Found on turnips by Mr. Haliday. 



4. M. fulgurans Hal. — Length 3|: lines. Ochreous, tips of antennae and 



eyes dark : abdomen ferruginous-ochre : stigma pallid. 

 Taken in shady ravines in Ireland. 



5. M. basalis Curt. — Length 3 lines. Ochreous; eyes, crown of head, 



3 spots on the thorax, postscutellum, base of abdomen (excepting 

 the posterior margin of the 2nd segment), and a spot on each side 

 the 3rd segment, black : base and tips of posterior tibiae black. 

 New Forest, on stumps of trees in shady groves, beginning of June. 



6. M. Sylvarum Hal. — Length 3 lines. Black, orbit of eyes and mouth 



pale yellow, mesothorax and scutellum ferruginous, the former 

 with 3 black spots, and a brownish spot sometimes on the back 

 of the abdomen. Legs ochreous, tips of tarsi fuscous. 

 Abundant on trees in hedge-rows, particularly ash and oak, Mr. 

 Haliday. 



II. Interior brachial cell of the lower wings emitting 2 ner- 

 vures from its inner angle. 



7. M. sericans Hal— Curt. Brit. Ent. pi. 464. <? . 



Black, with a dull blueish bloom, and clothed with pale pu- 

 bescence ; face and mouth yellow, underside of antennae ochreous- 

 brown, an ochreous dot at the angles of the basal joint of the body, 

 and a scutiform spot on the margin of the 2nd, and the base of 

 the 3rd of the same colour ; the posterior margin of the latter 

 and the tip of the abdomen ochreous : wings stained yellow, the 

 nervures and stigma pale brown : legs ochreous, thighs reddish, 

 tips of the posterior and of their tibiae blackish; posterior tarsi 

 brown, the others brown only at their tips. 

 Taken by Mr. Haliday, I believe, near Belfast. 



8. M. Splenium Curt. — Length 2j lines. Male pale ochreous; head 



black, face yellowish-white, antennae fuscous, except at the base; 

 alitrunk black, scutellum bright ochre ; abdomen with the base 

 of the 1st joint and sides of 2nd black, sides of the remainder, 

 and a considerable portion of the apex and the styles, brown : 

 centre of stigma pale ochre ; nervures, tips of posterior tibiae, 

 pulvilli and claws brown. 

 This pretty species I took in the New Forest. 



Mr. Haliday has at least twenty- six very distinct species of 

 this genus. 



The Plant is Cuscuta Epithyrmm (Less Dodder).
