A small, linear, black and shining species. Head somewhat short and 

 circularly contracted behind the eyes ; face centrally tuberculate ; mouth 

 infuscate with clypeus often apically rufescent ; frons subconvex and 

 closely punctate ; cheeks not buccate and clypeus discreted ; mandibles 

 at the base dorsally convex with the external margin not reflexed ; labrum 

 of (J stramineous or dull ferrugineous. Antennae half the length of the 

 body or a little longer ; ferrugineous beneath, with the scape black ; 9 

 flagellum filiform with the basal joint half as long again as the second, 

 which is about as long as the third ; of (J apically attenuate with the 

 scape sometimes substramineous beneath. Thorax immaculate ; pleurae 

 not alutaceous but strongly and not very closely punctate ; metathorax 

 with often complete upper areae, the basal area and oblique costulae 

 being especially distinct. Abdomen sublinear, strongly punctate and 

 nitidulous with the anus smooth ; the three basal incisures subcastane- 

 ous ; first segment basally produced, slightly curved, marginate above and 

 depressed on either side before the rounded apical angles, with carinae 

 extending beyond the centre ; the second and third subtransverse and 

 punctate, following nitidulous ; terebra half as long again as the body. 

 Legs normal, pale red with the hind coxae sometimes partly, and their 

 tarsi towards the apex, infuscate with the fifth joint longer than the 

 fourth. Wings subhyaline ; radix, tegulae and stigma stramineous, the 

 last being occasionally piceous. Length, 4 — 6 mm. 



The J sometimes has the abdomen entirely black ; and the var. Urcs 

 has the posterior coxae and trochanters centrally infuscate and the hind 

 tarsi, with the apices of their tibiae, nigrescent. Holmgren's species is 

 noAv considered distinct from that of Gravenhorst. 



Bridgman (Trans. Norf. Soc. v, p. 68) says G. bifoveolata is very closely 

 allied ^ith G. sciilpturafa, from which it mainly differs in the more strongly 

 contracted base of the head and the paler stigma ; the disparity of size 

 will immediately separate them. 



It occurs on the Continent in August ; and is recorded by Hope from 

 Netley in Shropshire, and as common at Earlham near Norwich by Bridg- 

 man, who tells us fix.) that Fletcher has bred it from an unascertained 

 host, probably at Worthing. It has also been bred by Elisha from 

 Ephippiphora foeneana and by Weston ixom. Dicrorampha simplicia7ia (Fitch, 

 Entom, 1880, p. 68 et 1883, p. 67). Maquand records it from the Lands 

 End district, and Bignell from Bickleigh in Devon, late in August ; Hamm 

 has sent me specimens from Ogly Bog, near Oxford, in July and Bovey 

 Tracy, in south Devon, in August ; Butler from Wymondley in Herts ; 

 and Gordon from Wigtonshire, in June. I possess specimens taken by 

 Marshall at Botusfleming, in Cornwall ; Bridgman at Earlham, as noticed 

 above {cf. also Trans. Norf. Soc. v, p. 66) ; Capron at Shere and W. 

 Saunders at Greenings, in Surrey ; Piffard at Felden, in Herts ; Butler at 

 Hastings ; and Tuck at Bungay, Aldeburgh, Bury St. Edmunds and Tos- 

 tock, in Suffolk. This is by far the most abundant species of the genus 

 and occurs freely on the flowers of Spiraea ulinariay Angeliea sjlvestris,
